Background
Multiple vulnerabilities have recently been identified in the managed file transfer (MFT) software MOVEit developed by Ipswitch, Inc. and produced by Progress Software. These include CVE-2023-34362 [1], CVE-2023-35036 [2] and CVE-2023-35708 [3]. These vulnerabilities allow adversaries to gain unauthorized access and escalate privileges in the environment.
MOVEit is a popular tool that is used by thousands of organizations around the world. These include organizations in the public, private, and government sectors. The transfer software can be deployed as on-prem, in the MOVEit Cloud, or on any Microsoft Azure server. Due to the nature of handling potentially sensitive information, MOVEit is a lucrative target from a threat actor’s perspective, granting threat actors the ability to add and remove database content, execute arbitrary code, and steal sensitive information.
What do we know about the exploits?
While this story is still actively playing out and we will know the final count only in the coming weeks, here’s what we know about it thus far.
The CL0p ransomware gang has been actively exploiting this vulnerability and has claimed to compromise over dozens of organizations across different industries and regions. These include oil & gas, news & media, healthcare, financial services, state and federal governments, and more. Anomali’s own assessment has shown that there are thousands of externally exposed MOVEit instances that could potentially be exploited.
Additional public research has revealed that this vulnerability may have been actively exploited even since 2021 [4]. More recently, organizations have also released proof of concept (PoC) exploit code for this vulnerability [5], making it likely that other attackers could exploit unpatched systems.
Anomali MOVEit Vulnerability Dashboard
The Anomali Threat Research team has additionally researched and documented additional details on this vulnerability via Threat Bulletin. The team has also identified over 430 relevant indicators and signatures and several sector specific articles to provide more industry-specific details.

(Publié: 27 mai 2023)
Force Shadow est une menace qui cible les organisations sud-coréennes depuis 2013. Il cible principalement les serveurs Windows.Les chercheurs d'AHNLAB ont analysé l'activité du groupe en 2020-2022.Les activités de force fantôme sont relativement faciles à détecter car les acteurs ont tendance à réutiliser les mêmes noms de fichiers pour leurs logiciels malveillants.Dans le même temps, le groupe a évolué: après mars, ses fichiers dépassent souvent 10 Mo en raison de l'emballage binaire.Les acteurs ont également commencé à introduire divers mineurs de crypto-monnaie et une nouvelle porte dérobée surnommée Viticdoor.
Commentaire de l'analyste: Les organisations doivent garder leurs serveurs à jour et correctement configurés avec la sécurité à l'esprit.Une utilisation et une surchauffe du processeur inhabituellement élevées peuvent être un signe du détournement de ressources malveillantes pour l'exploitation de la crypto-monnaie.Les indicateurs basés sur le réseau et l'hôte associés à la force fantôme sont disponibles dans la plate-forme Anomali et il est conseillé aux clients de les bloquer sur leur infrastructure.

CloudWizard APT: La mauvaise histoire magique continue
(Publié: 19 mai 2023)
Un cadre de logiciel malveillant modulaire nouvellement découvert surnommé CloudWizard est actif depuis 2016. Les chercheurs de Kaspersky ont pu le connecter à des activités de menace persistante avancées précédemment enregistrées: Operation Groundbait et le Prikormka Malware (2008-2016), Operation Bugdrop (2017), PowerMagic (2020-2022) et Common Magic (2022).Semblable à ces campagnes précédentes, CloudWizard cible des individus, des organisations diplomatiques et des organisations de recherche dans les régions de Donetsk, de Lugansk, de Crimée, du centre et de l'ouest de l'Ukraine.Les deux modules principaux de CloudWizard effectuent le chiffrement et le décryptage de toutes les communications et relayez les données cryptées au cloud ou au C2 basé sur le Web.Les modules supplémentaires permettent de prendre des captures d'écran, un enregistrement de microphone, un keylogging et plus encore.
Commentaire des analystes: Auparavant, les chercheurs de l'ESET ont conclu que les acteurs derrière l'opération Groundbait opérent très probablement à partir de l'Ukraine, mais que les chercheurs de Kaspersky ne partaient pas s'ils sont d'accord avec cette attribution.Les guerres et les conflits militaires attirent une cyber-activité supplémentaire.Tous les indicateurs CloudWizard connus sont disponibles dans la plate-forme Anomali et il est conseillé aux clients de les bloquerleur infrastructure.

Deconstructing Amadey’s Latest Multi-Stage Attack and Malware Distribution
(published: May 5, 2023)
McAfee researchers have detected a multi-stage attack that starts with a trojanized wextract.exe, Windows executable used to extract files from a cabinet (CAB) file. It was used to deliver the AgentTesla, Amadey botnet, LockBit ransomware, Redline Stealer, and other malicious binaries. To avoid detection, the attackers use obfuscation and disable Windows Defender through the registry thus stopping users from turning it back on through the Defender settings.
Analyst Comment: Threat actors are always adapting to the security environment to remain effective. New techniques can still be spotted with behavioral analysis defenses and social engineering training. Users should report suspicious files with double extensions such as .EXE.MUI. Indicators associated with this campaign are available in the Anomali platform and users are advised to block these on their infrastructure.

Eastern Asian Android Assault – FluHorse
(published: May 4, 2023)
Active since May 2022, a newly-detected Android stealer dubbed FluHorse spreads mimicking popular apps or as a fake dating application. According to Check Point researchers, FluHorse was targeting East Asia (Taiwan and Vietnam) while remaining undetected for months. This stealthiness is achieved by sticking to minimal functions while also relying on a custom virtual machine that comes with the Flutter user interface software development kit. FluHorse is being distributed via emails that prompt the recipient to install the app and once installed, it asks for the user’s credit card or banking data. If a second factor authentication is needed to commit banking fraud, FluHorse tells the user to wait for 10-15 minutes while intercepting codes by installing a listener for all incoming SMS messages.
Analyst Comment: FluHorse\'s ability to remain undetected for months makes it a dangerous threat. Users should avoid installing applications following download links received via email or other messaging. Verify the app authenticity on the official com |

Depuis 2022, le groupe parrainé par le Nord-Korea APT37 (Group123, Ricochet Chollima) a principalement changé ses méthodes de livraison de Maldocs pour cacher des charges utiles à l'intérieur des fichiers LNK surdimensionnés.Vérifier les chercheurs a identifié plusieurs chaînes d'infection utilisées par le groupe de juillet 2022 à avril 2023. Celles-ci ont été utilisées pour livrer l'un des outils personnalisés de l'APT37 (Goldbackdoor et Rokrat), ou le malware de marchandises Amadey.Tous les leurres étudiés semblent cibler des personnes coréennes avec des sujets liés à la Corée du Sud.
Commentaire de l'analyste: Le passage aux chaînes d'infection basées sur LNK permet à APT37 de l'interaction utilisateur moins requise car la chaîne peut être déclenchée par un simple double clic.Le groupe continue l'utilisation de Rokrat bien triés qui reste un outil furtif avec ses couches supplémentaires de cryptage, le cloud C2 et l'exécution en mémoire.Les indicateurs associés à cette campagne sont disponibles dans la plate-forme Anomali et il est conseillé aux clients de les bloquerleur infrastructure.

A new Monero cryptocurrency-mining campaign is the first recorded case of gaining persistence via Kubernetes (K8s) Role-Based Access Control (RBAC), according to Aquasec researchers. The recorded honeypot attack started with exploiting a misconfigured API server. The attackers preceded by gathering information about the cluster, checking if their cluster was already deployed, and deleting some existing deployments. They used RBAC to gain persistence by creating a new ClusterRole and a new ClusterRole binding. The attackers then created a DaemonSet to use a single API request to target all nodes for deployment. The deployed malicious image from the public registry Docker Hub was named to impersonate a legitimate account and a popular legitimate image. It has been pulled 14,399 times and 60 exposed K8s clusters have been found with signs of exploitation by this campaign.
Analyst Comment: Your company should have protocols in place to ensure that all cluster management and cloud storage systems are properly configured and patched. K8s buckets are too often misconfigured and threat actors realize there is potential for malicious activity. A defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) approach is a good mitigation step to help prevent actors from highly-active threat groups.

Investigation of the previously-reported 3CX supply chain compromise (March 2023) allowed Mandiant researchers to detect it was a result of prior software supply chain attack using a trojanized installer for X_TRADER, a software package provided by Trading Technologies. The attack involved the publicly-available tool SigFlip decrypting RC4 stream-cipher and starting publicly-available DaveShell shellcode for reflective loading.

banquier QBOT livré par correspondance commerciale
(Publié: 17 avril 2023)
Début avril 2023, un volume accru de Malspam en utilisant le détournement de fil commercial-imail a été détecté pour fournir le troin bancaire QBOT (QAKBOT, Quackbot, Pinkslipbot).Les leurres observés en anglais, en allemand, en italien et en français visaient divers pays, les trois premiers étant l'Allemagne, l'Argentine et l'Italie, dans cet ordre.Les attaquants usurpaient un nom dans la conversation détournée pour inciter la cible à ouvrir un fichier PDF ci-joint.La cible est ensuite confrontée à un bouton, à un mot de passe et à une instruction pour télécharger, déballer et exécuter un fichier de script Windows malveillant (WSF) dans une archive protégée par mot de passe.L'exécution des utilisateurs est suivie d'une désobfuscation automatisée d'un JScript contenu produisant un script PowerShell codé visant à télécharger une DLL QBOT à partir d'un site Web compromis et à l'exécuter à l'aide de RunDLL32.QBOT vole les informations d'identification, profil les systèmes pour identifier les perspectives de ciblage supplémentaire de grande valeur et vole des e-mails stockés localement pour une prolifération supplémentaire via le détournement de fil calspam.
Commentaire de l'analyste: L'usurpation du nom de l'expéditeur des lettres précédentes du & lsquo; from & rsquo;Le champ peut être identifié dans cette campagne car il utilise une adresse e-mail frauduleuse de l'expéditeur différent de celle du véritable correspondant.Les utilisateurs doivent être prudents avec des archives protégées par mot de passe et des types de fichiers suspects tels que WSF.Les indicateurs de réseau et d'hôtes associés à cette campagne QBOT sont disponibles dans la plate-forme Anomali et il est conseillé aux clients de les bloquer sur leur infrastructure.

campagne de phishingCible l'industrie chinoise de l'énergie nucléaire
(Publié: 24 mars 2023)
Actif Depuis 2013, le groupe amer (T-APT-17) est soupçonné d'être parrainé par le gouvernement indien.Des chercheurs Intezer ont découvert une nouvelle campagne amère ciblant les universitaires, le gouvernement et d'autres organisations de l'industrie de l'énergie nucléaire en Chine.Les techniques sont cohérentes avec les campagnes amères observées précédemment.L'intrusion commence par un e-mail de phishing censé provenir d'un véritable employé de l'ambassade du Kirghizistan.Les pièces jointes malveillantes observées étaient soit des fichiers HTML (CHM) compilés à Microsoft, soit des fichiers Microsoft Excel avec des exploits d'éditeur d'équation.L'objectif des charges utiles est de créer de la persistance via des tâches planifiées et de télécharger d'autres charges utiles de logiciels malveillants (les campagnes amères précédentes ont utilisé le voleur d'identification du navigateur, le voleur de fichiers, le keylogger et les plugins d'outils d'accès à distance).Les attaquants se sont appuyés sur la compression LZX et la concaténation des cordes pour l'évasion de détection.
Commentaire de l'analyste: De nombreuses attaques avancées commencent par des techniques de base telles que des e-mails injustifiés avec une pièce jointe qui oblige l'utilisateur à l'ouvrir.Il est important d'enseigner l'hygiène de base en ligne à vos utilisateurs et la sensibilisation au phishing.Il est sûr de recommander de ne jamais ouvrir de fichiers CHM joints et de garder votre bureau MS Office entièrement mis à jour.Tous les indicateurs connus associés à cette campagne amère sont disponibles dans la plate-forme Anomali et il est conseillé aux clients de les bloquer sur leur infrastructure.

Xenomorph V3: a New Variant with ATS Targeting More Than 400 Institutions
(published: March 10, 2023)
Newer versions of the Xenomorph Android banking trojan are able to target 400 applications: cryptocurrency wallets and mobile banking from around the World with the top targeted countries being Spain, Turkey, Poland, USA, and Australia (in that order). Since February 2022, several small, testing Xenomorph campaigns have been detected. Its current version Xenomorph v3 (Xenomorph.C) is available on the Malware-as-a-Service model. This trojan version was delivered using the Zombinder binding service to bind it to a legitimate currency converter. Xenomorph v3 automatically collects and exfiltrates credentials using the ATS (Automated Transfer Systems) framework. The command-and-control traffic is blended in by abusing Discord Content Delivery Network.
Analyst Comment: Fraud chain automation makes Xenomorph v3 a dangerous malware that might significantly increase its prevalence on the threat landscape. Users should keep their mobile devices updated and avail of mobile antivirus and VPN protection services. Install only applications that you actually need, use the official store and check the app description and reviews. Organizations that publish applications for their customers are invited to use Anomali's Premium Digital Risk Protection service to discover rogue, malicious apps impersonating your brand that security teams typically do not search or monitor.

MQsTTang: Mustang Panda’s Latest Backdoor Treads New Ground with Qt and MQTT
(published: March 2, 2023)
In early 2023, China-sponsored group Mustang Panda began experimenting with a new custom backdoor dubbed MQsTTang. The backdoor received its name based on the attribution and the unique use of the MQTT command and control (C2) communication protocol that is typically used for communication between IoT devices and controllers. To establish this protocol, MQsTTang uses the open source QMQTT library based on the Qt framework. MQsTTang is delivered through spearphishing malicious link pointing at a RAR archive with a single malicious executable. MQsTTang was delivered to targets in Australia, Bulgaria, Taiwan, and likely some other countries in Asia and Europe.
Analyst Comment: Mustang Panda is likely exploring this communication protocol in an attempt to hide its C2 traffic. Defense-in-depth approach should be used to stop sophisticated threats that evolve and utilize various techniques of defense evasion. Sensitive government sector workers should be educated on spearphishing threats and be wary of executable files delivered in archives.

WinorDLL64: A Backdoor From The Vast Lazarus Arsenal?
(published: February 23, 2023)
When the Wslink downloader (WinorLoaderDLL64.dll) was first discovered in 2021, it had no known payload and no known attribution. Now ESET researchers have discovered a Wslink payload dubbed WinorDLL64. This backdoor uses some of Wslink functions and the Wslink-established TCP connection encrypted with 256-bit AES-CBC cipher. WinorDLL64 has some code similarities with the GhostSecret malware used by North Korea-sponsored Lazarus Group.
Analyst Comment: Wslink and WinorDLL64 use a well-developed cryptographic protocol to protect the exchanged data. Innovating advanced persistent groups like Lazarus often come out with new versions of their custom malware. It makes it important for network defenders to leverage the knowledge of a wider security community by adding relevant premium feeds and leveraging the controls automation via Anomali Platform integrations.

Coinbase Cyberattack Targeted Employees with Fake SMS Alert
(published: February 20, 2023)
On February 5th, 2023, several employees at the Coinbase cryptocurrency exchange platform received a fake SMS alert on their mobile phones. The message indicated that they need to urgently log in via the link provided to receive an important message. One employee got phished by the attackers, but they failed to login due to the MFA restrictions. The attackers, likely associated with the previously-documented 0ktapus phishing campaign, proceeded to call the employee and phish him for more information by pretending to be from the corporate IT. Coinbase was able to detect the unusual activity and stop the breach, although the attackers have obtained some contact information belonging to multiple Coinbase employees in addition to the login credentials of the phished user.
Analyst Comment: Network defenders are advised to monitor for access attempts from a third-party VPN provider, such as Mullvad VPN. Monitor for download of remote desktop viewers such as AnyDesk or ISL Online. Set up monitoring for Incoming phone calls / text messages from Bandwidth dot com, Google Voice, Skype, and Vonage/Nexmo. Anomali Premium Domain Monitoring service notifies customers regarding registration of potential phishing domains. And as always with these types of social engineering attacks employee awareness is key - not just of the threat but how to independently verify the legitimacy of any contact and what to do with anything suspicious.

Earth Kitsune Delivers New WhiskerSpy Backdoor via Watering Hole Attack
(published: February 17, 2023)
Since the end of 2022, a new campaign by the state-sponsored Earth Kitsune group targets visitors of pro-North Korea websites. A malicious JavaScript embedded into their video pages prompts a viewer to download a codec installer. Only visitors from particular subnets located in Nagoya, Japan and Shenyang, China, and users of a VPN provider in Brazil are receiving the malicious payload. The legitimate codec installer was patched to increase the PE image size and add an additional section. The attackers employ elliptic cryptography to protect encryption keys and use rare hashing algorithms: 32-bit Fowler-Noll-Vo hash (FNV-1) to compute machine IDs and a 32-bit Murmur3 hash of the 16-byte AES key to compute the |

#StopRansomware: Ransomware Attacks on Critical Infrastructure Fund DPRK Malicious Cyber Activities
(published: February 9, 2023)
The US and South Korea issued a joint advisory on ongoing, North Korea-sponsored ransomware activity against healthcare and other critical infrastructure. The proceedings are used to fund North Korea’s objectives including further cyber attacks against the US and South Korean defense and defense industrial base sectors. For initial access, the attackers use a trojanized messenger (X-Popup) or various exploits including those targeting Apache log4j2 and SonicWall appliances. Despite having two custom ransomware crypters, Maui and H0lyGh0st, the attackers can portray themselves as a different ransomware group (REvil) and/or use publicly-available crypters, such as BitLocker, Deadbolt, ech0raix, GonnaCry, Hidden Tear, Jigsaw, LockBit 2.0, My Little Ransomware, NxRansomware, Ryuk, and YourRansom.
Analyst Comment: Organizations in the healthcare sector should consider following the Cross-Sector Cybersecurity Performance Goals developed by the U.S. Cybersecurity and Infrastructure Security Agency and the U.S. National Institute of Standards and Technology. Follow the principle of least privilege by using standard user accounts on internal systems instead of administrative accounts. Turn off weak or unnecessary network device management interfaces.

2023-02-09 09:45:00 | Transforming Threat Data into Actionable Intelligence (lien direct) | Introduction In today's digital age, the threat of cyber-attacks is greater than ever. Traditional security operations, which have focused on reactive measures such as patching vulnerabilities and responding to breaches, are no longer sufficient to meet the challenges of the modern threat landscape. As a result, security organizations are shifting their focus to proactive measures to stay ahead of emerging threats. This shift towards proactive security operations is the focus of a new five-article series written by analysts at TAG Cyber. The series examines the latest trends and challenges for cybersecurity teams and explores the cutting-edge solutions that are helping security organizations become more proactive in their defense against cyber-attacks. Anomali's solutions are important in helping security operations (secops) teams move from a reactive to a proactive security program. Anomali, a leading threat intelligence provider and incident management software, offers a viable solution. Anomali's platform enables security teams to quickly and easily identify and respond to emerging threats by providing real-time visibility into the latest cyber threats and vulnerabilities, allowing organizations to take proactive measures to protect themselves from potential attacks instead of simply reacting to breaches after they have occurred. The series also delves into the strategies and technologies that can help CISOs and secops teams improve their operations. Anomali's platform is a key element in integrating threat intelligence with other technologies, such as Extended Detection and Response (XDR) and Attack Surface Management (ASM), to enhance the overall security posture of an organization. Additionally, Anomali's solutions assist with digital risk protection (DRP) in identifying and mitigating the risks associated with third-party vendors and partners. In summary, the series provides an in-depth look at the latest strategies and technologies to help CISOs and security teams become more proactive in their defense against cyber attacks. Anomali's solutions play a crucial role in this shift and assist organizations in identifying and mitigating emerging threats, integrating with other technologies, while addressing the skills gap. Article 1: Transforming Threat Data into Actionable Intelligence Christopher R. Wilder, TAG Cyber This article is the first in a series of guest blogs written by TAG Cyber analysts in conjunction with our colleagues at Anomali. Our five-part series of blogs focus on how threat-intelligence management integrates with extended detection and response (XDR) to increase operational efficiencies in an enterprise security operations environment and drive actionable prevention, detection, and response. The commercial Anomali platform demonstrates how integration between threat intelligence and XDR can work in the field. Threat intelligence is divided into three main categories: strategic, operational, and tactical. Strategic threat intelligence focuses on understanding the overall threat landscape and identifying long-term trends. It informs strategic decisions and helps organizations understand the potential risks they face. Operational threat intelligence identifies and responds to specific threats in real-time. It informs an organization’s day-to-day operations and helps protect against immediate threats. Tactical threat intelligence provides detailed information about specific threats, such as the tools, techniques, and procedures used by attackers. It also apprises tactical decisions and helps organizations respond to incidents. Threat intelligence is essential to any security program, providing organizations with the information they need to identify and respond to potential threats proactively.

No Pineapple! –DPRK Targeting of Medical Research and Technology Sector
(published: February 2, 2023)
In August-November 2022, North Korea-sponsored group Lazarus has been engaging in cyberespionage operations targeting defense, engineering, healthcare, manufacturing, and research organizations. The group has shifted their infrastructure from using domains to be solely IP-based. For initial compromise the group exploited known vulnerabilities in unpatched Zimbra mail servers (CVE-2022-27925 and CVE-2022-37042). Lazarus used off the shelf malware (Cobalt Strike, JspFileBrowser, JspSpy webshell, and WSO webshell), abused legitimate Windows and Unix tools (such as Putty SCP), and tools for proxying (3Proxy, Plink, and Stunnel). Two custom malware unique to North Korea-based advanced persistent threat actors were a new Grease version that enables RDP access on the host, and the Dtrack infostealer.
Analyst Comment: Organizations should keep their mail server and other publicly-facing systems always up-to-date with the latest security features. Lazarus Group cyberespionage attacks are often accompanied by stages of multi-gigabyte exfiltration traffic. Suspicious connections and events should be monitored, detected and acted upon. Use the available YARA signatures and known indicators.

Chinese PlugX Malware Hidden in Your USB Devices?
(published: January 26, 2023)
Palo Alto researchers analyzed a PlugX malware variant (KilllSomeOne) that spreads via USB devices such as floppy, thumb, or flash drives. The variant is used by a technically-skilled group, possibly by the Black Basta ransomware. The actors use special shortcuts, folder icons and settings to make folders impersonating disks and a recycle bin directory. They also name certain folders with the 00A0 (no-break space) Unicode character thus hindering Windows Explorer and the command shell from displaying the folder and all the files inside it.
Analyst Comment: Several behavior detections could be used to spot similar PlugX malware variants: DLL side loading, adding registry persistence, and payload execution with rundll32.exe. Incidents responders can check USB devices for the presence of no-break space as a folder name.

Roaming Mantis Implements New DNS Changer in Its Malicious Mobile App in 2022
(published: January 19, 2023)
In December 2022, a financially-motivated group dubbed Roaming Mantis (Shaoye) continued targeting mobile users with malicious landing pages. iOS users were redirected to phishing pages, while Android users were provided with malicious APK files detected as XLoader (Wroba, Moqhao). Japan, Austria, France, and Germany were the most targeted for XLoader downloads (in that order). All but one targeted country had smishing as an initial vector. In South Korea, Roaming Mantis implemented a new DNS changer function. XLoader-infected Android devices were targeting specific Wi-Fi routers used mostly in South Korea. The malware would compromise routers with default credentials and change the DNS settings to serve malicious landing pages from legitimate domains.
Analyst Comment: The XLoader DNS changer function is especially dangerous in the context of free/public Wi-Fi that serve many devices. Install anti-virus software for your mobile device. Users should be cautious when receiving messages with a link or unwarranted prompts to install software.

Hook: a New Ermac Fork with RAT Capabilities
(published: January 19, 2023)
ThreatFabric researchers analyzed a new Android banking trojan named Hook. It is a rebranded development of the Ermac malware that was based on the Android banker Cerberus. Hook added new capabilities in targeting banking and cryptocurrency-related applications. The malware also added capabilities of a remote access trojan and a spyware. Its device take-over capabilities include being able to remotely view and interact with the screen of the infected device, manipulate files on the devices file system, simulate clicks, fill text boxes, and perform gestures. Hook can start the social messaging application WhatsApp, extract all the messages present, and send new ones.
Analyst Comment: Users should take their mobile device security seriously whether they use it for social messaging or actually provide access to their banking accounts and/or cryptocurrency holdings. Similar to its predecessors, Hook will likely be used by many threat actors (malware-as-as-service model).

OPWNAI : Cybercriminals Starting to Use ChatGPT
(published: January 6, 2023)
Check Point researchers have detected multiple underground forum threads outlining experimenting with and abusing ChatGPT (Generative Pre-trained Transformer), the revolutionary artificial intelligence (AI) chatbot tool capable of generating creative responses in a conversational manner. Several actors have built schemes to produce AI outputs (graphic art, books) and sell them as their own. Other actors experiment with instructions to write an AI-generated malicious code while avoiding ChatGPT guardrails that should prevent such abuse. Two actors shared samples allegedly created using ChatGPT: a basic Python-based stealer, a Java downloader that stealthily runs payloads using PowerShell, and a cryptographic tool.
Analyst Comment: ChatGPT and similar tools can be of great help to humans creating art, writing texts, and programming. At the same time, it can be a dangerous tool enabling even low-skill threat actors to create convincing social-engineering lures and even new malware.

Russia-sponsored group Turla re-registered expired domains for old Andromeda malware to select a Ukrainian target from the existing victims. Andromeda sample, known from 2013, infected the Ukrainian organization in December 2021 via user-activated LNK file on an infected USB drive. Turla re-registered the Andromeda C2 domain in January 2022, profiled and selected a single victim, and pushed its payloads in September 2022. First, the Kopiluwak profiling tool was downloaded for system reconnaissance, two days later, the Quietcanary backdoor was deployed to find and exfiltrate files created in 2021-2022.
Analyst Comment: Advanced groups are often utilizing commodity malware to blend their traffic with less sophisticated threats. Turla’s tactic of re-registering old but active C2 domains gives the group a way-in to the pool of existing targets.

2023-01-05 05:50:00 | Focusing on Your Adversary (lien direct) | Every day, we hear news stories or read articles about data breaches and other cyber security threats. As malicious threat actors and the risk of cyber threats increase, protecting networks and valuable information becomes more critical. So what can organizations do to ensure their networks remain secure? Organizations must understand their adversaries’ identities to keep data safe and protect it from cyber-attacks. This article will explore the different types of threats facing enterprise organizations and what they can do to stay ahead of them. Evolving Cyber Attacks Cyber attacks are constantly evolving as attackers continue to find new ways to exploit vulnerabilities. This includes: Increased use of artificial intelligence (AI) and machine learning: Attackers are using AI and machine learning to automate and improve the effectiveness of their attacks. For example, AI can be used to generate convincing phishing emails or to bypass security systems. Rise of ransomware: Ransomware attacks, which involve encrypting a victim’s data and demanding a ransom to decrypt it, have become increasingly common in recent years. Ransomware attacks can significantly impact businesses, disrupting operations and resulting in financial losses. More targeted attacks: Rather than broad-based attacks that aim to compromise as many systems as possible, attackers are increasingly using targeted attacks designed to exploit a particular organization’s vulnerabilities. Increased focus on mobile devices: Mobile devices, such as smartphones and tablets, are becoming increasingly vulnerable to cyber-attacks. As a result, attackers focus more on exploiting these devices’ vulnerabilities. Increased use of cloud services: As more organizations move to the cloud, attackers are finding new ways to exploit vulnerabilities in these systems. For example, attackers may try to gain access to an organization’s cloud-based data or disrupt its cloud-based operations. It’s not only crucial for organizations to stay up-to-date on the latest trends in cyber attacks and to implement appropriate security measures to protect against them. It’s even more important to pinpoint your adversaries to understand their TTPs to protect and predict their next attack. Types of Adversaries There are many different types of cybersecurity adversaries that organizations have to deal with. Some common types of adversaries include: Hackers: Individuals or groups who attempt to gain unauthorized access to systems or networks for various reasons, such as stealing data, disrupting operations, or causing damage. Cybercriminals: Individuals or groups who use the internet to commit crimes, such as identity theft, fraud, or extortion. Cyber Terrorists: A group that’s goal is to disrupt operations, cause harm, and destroy data. Increasingly targeting critical infrastructures such as power plants, water treatment facilities, transportation systems, and healthcare providers. Nation-state actors: Governments or government-sponsored organizations that use cyber attacks as part of their foreign policy or military operations. Insider threats: Individuals with legitimate access to an organization’s systems or networks use that access to cause harm or steal sensitive information. Malicious insiders: These are individuals who are intentionally malicious and seek to cause harm to an organization’s systems or networks. Hacktivists: The term “hacktivists” refers to people who use hacking techniques to disrupt computer systems and networks in pursuit of political goals. Hackers often work alone, though some groups do exist.

PyTorch Discloses Malicious Dependency Chain Compromise Over Holidays
(published: January 1, 2023)
Between December 25th and December 30th, 2022, users who installed PyTorch-nightly were targeted by a malicious library. The malicious torchtriton dependency on PyPI uses the dependency confusion attack by having the same name as the legitimate one on the PyTorch repository (PyPI takes precedence unless excluded). The actor behind the malicious library claims that it was part of ethical research and that he alerted some affected companies via HackerOne programs (Facebook was allegedly alerted). At the same time the library’s features are more aligned with being a malware than a research project. The code is obfuscated, it employs anti-VM techniques and doesn’t stop at fingerprinting. It exfiltrates passwords, certain files, and the history of Terminal commands. Stolen data is sent to the C2 domain via encrypted DNS queries using the wheezy[.]io DNS server.
Analyst Comment: The presence of the malicious torchtriton binary can be detected, and it should be uninstalled. PyTorch team has renamed the 'torchtriton' library to 'pytorch-triton' and reserved the name on PyPI to prevent similar attacks. Opensource repositories and apps are a valuable asset for many organizations but adoption of these must be security risk assessed, appropriately mitigated and then monitored to ensure ongoing integrity.

New RisePro Stealer Distributed by the Prominent PrivateLoader
(published: December 22, 2022)
RisePro is a new commodity infostealer that is being sold and supported by Telegram channels. Log credentials derived from RisePro are for sale on illicit markets since December 13, 2022. RisePro targets password stores and particular file patterns to extract cookies, credit card information, cryptocurrency wallets, installed software credentials, and passwords. RisePro was delivered by PrivateLoader and these two malware families have significant code similarity. It also shares similarity with the Vidar stealer in a way that both use dropped DLL dependencies.
Analyst Comment: Infostealers are a continually rising threat for organizations especially with hybrid workers utilizing their own and other non-corporate devices to access cloud based resources and applications. Information from these sessions, useful to attackers, can be harvested unknown to the worker or end organization. In addition, the rise of threat actor reliance on potent commodity malware is one of the trends that Anomali analysts observe going into 2023 (see Predictions below). Network defenders are advised to block known PrivateLoader and RisePro indicators (available on the Anomali platform).

2022-12-21 05:11:00 | 2023 Anomali Predictions: New Risks to Put Added Pressure on Enterprise Defenders (lien direct) | Cybersecurity has a way of surprising us with the unexpected so I wouldn’t be surprised to see a completely new kind of security threat emerge in 2023. But as the ongoing cat-and-mouse game between attackers and defenders unfolds, certain scenarios are already coming into view. Why Threat Actors Will Love Pink Slips Amid growing economic uncertainty, many companies around the globe are tightening their belts and reducing headcount in advance of a possible economic recession. But as organizations brace for the worst, three related security risks now loom: 1. External attackers aren’t the only threats companies face. Insider threat incidents are up 44% in the past two years, as costs per incident have climbed more than a third to $15.38 million. But there’s new reason for concern since layoffs create insider threat risks – either in the form of disgruntled employees or among existing employees angry about corporate’s decision to let go of colleagues. That means more potential for theft or sabotage from within. 2. Staff reductions have unintended consequences on an organization’s security posture. When gaps in network defenses suddenly appear, the company now has fewer technical experts watching the situation. At the same time, the organization now has less visibility into the security status of its various products and systems. This presents a golden opportunity for professional threat actors searching out the path of least resistance. When they hear about layoff announcements at a particular firm, it doesn’t take very long before attackers start probing for security vulnerabilities. 3. Companies regularly get into trouble by failing to set up well-controlled and thorough off-boarding personnel procedures – particularly when it comes to senior or privileged users. Proper processes with verification of completion on user accounts, data, assets, etc. is critical. Also, don’t ignore the consequences of adding roles and responsibilities to remaining employees who may shoulder added responsibilities following a staff layoff. There are risks in maintaining segregation of duties and inadvertently creating ‘super users.’ This could pose an insider threat risk or present targets of opportunity for attackers looking to exploit ‘novices’ in new roles they have taken on. Commodity Malware and Tools Dominate Threat actor groups operate a profitable business selling increasingly complex malware and tools to would-be attackers, a trend that will continue in 2023, making it even harder for forensic investigators to determine the origin of attacks. All of which further underscores the importance of better threat intelligence to understand why certain actors are likely to target specific organizations and what malware and tools they might deploy. Supply Chain Is the Place to Be Cyber attackers stick with what works. So, after the run of big supply chain breaches in the last few years – SolarWinds 2020, Log4Shell 2021 and its variants into 2022 – expect more of the same in the new year. The too-common occurrence of trusted relationship abuse and supply chain attacks is a particular favorite of state-sponsored groups. Look for them to demonstrate patience and remain hidden as they go to great lengths to accomplish their objectives. None of this means that attackers are fated to have the advantage over defenders in 2023. But given their growing sophistication, it’s more important than ever to have fuller awareness of your assets and supply chain vectors. Pay close attention to shared development environments, where you work with 3rd parties and contractors in developing and maintaining your applications. Maintaining oversight over the security and access to these environments is key. Assure development practices and establish adequate segregation of code bases, data, and documentation. It’s hard to suffici | Malware Threat Prediction | ★★★ | |

APT5: Citrix ADC Threat Hunting Guidance
(published: December 13, 2022)
On December 13, 2022, the US National Security Agency published a report on the ongoing exploitation of Citrix products. Citrix confirmed that this critical remote code execution vulnerability (CVE-2022-27518, CTX474995) affects Citrix Application Delivery Controller™ (Citrix ADC) and Citrix Gateway versions: 12.1 and 13.0 before 13.0-58.32. Active exploitation of the CVE-2022-27518 zero-day was attributed to China-sponsored APT5 (Keyhole Panda, Manganese, UNC2630) and its custom Tricklancer malware.
Analyst Comment: All customers using the affected builds are urged to install the current build or upgrade to the newest version (13.1 or newer) immediately. Anomali Platform has YARA signatures for the Tricklancer malware, network defenders are encouraged to follow additional NSA hunting suggestions (LINK). Check md5 hashes for key executables of the Citrix ADC appliance. Analyze your off-device logs: look for gaps and mismatches in logs, unauthorized modification of user permissions, unauthorized modifications to the crontab, and other known signs of APT5’s activities.

Linux Cryptocurrency Mining Attacks Enhanced via CHAOS RAT
(published: December 12, 2022)
In November 2022, a new cryptojacking campaign was detected by Trend Micro researchers. Unlike previously-recorded campaigns that aim at installing a cryptomining software, this one is utilizing a remote access trojan (RAT): a Linux-targeting version of the open-source Chaos RAT. This Go-based RAT is multi-functional and has the ability to download additional files, run a reverse shell, and take screenshots.
Analyst Comment: Implement timely patching and updating to your systems. Monitor for a sudden increase in resource utilization, track open ports, and check the usage of and changes made to DNS routing.

2022-12-15 05:12:00 | Anomali November Quarterly Product Update (lien direct) | We’re excited to announce our quarterly platform update for November. This update introduces new capabilities that automate defense actions and allow enterprise organizations to understand their relevant threat landscape and visualize what’s happening inside and outside their network. Key highlights for this quarter include: Attack Surface Management Visualizations of Attack Flow Patterns Anomali Intelligence Channels Cloud XDR Data Usage and Notification Feeds Health Status Attack Surface Management: Understanding your threat landscape is essential in knowing which assets you need to protect. With this release, we’re proud to offer a unique Attack Surface Management solution that provides cyber security teams with a comprehensive, accurate view of their environment through the eyes of the attacker. “Recent ESG Research showed that security operations have become more difficult at most organizations over the past few years, partly due to a growing attack surface,” said Jon Oltsik, Senior Principal Analyst and Fellow, Enterprise Strategy Group. Anomali’s Attack Surface Management provides visibility into ALL external facing assets to identify exposures, enabling organizations to understand impact based on asset criticality, vulnerability, and attack severity. This allows analysts to prioritize investigation activities and perform remediation of misconfigured assets and security controls. The real power is using it in combination with other Anomali solutions. For example, with Anomali Match, organizations can prioritize asset remediation based on real, detected threats to exposed assets. With this, they can assess the potential impact of the threat actors targeting organizations, their motivations for attacking, and their tactics and techniques as they carry out an active campaign. Anomali’s proprietary data provides a point in time and a historical view with insights that others can’t. Reach out or download our datasheet to learn more. Visualizations of Attack Flow Patterns: Understanding an attacker and their tools, techniques, and procedures TTPs is paramount to becoming a proactive security organization. “Attack flows help defenders understand, share, and make threat-informed decisions based on the sequence of actions in a cyber-attack,” as per MITRE Enginuity’s Center for Threat Informed Defense. Based upon our work with the MITRE Engenuity Center for Threat-Informed Defense, we’ve added a new Attack Flow Library that helps visualize the sequence of attack techniques in ThreatStream Cloud. An initial group of 15 Attack Flows is available in ThreatStream, curated by the Anomali Threat Research Team. This library enables analysts to understand attack pattern sequences for infiltrating an environment. It also provides SOC teams with a foundation for future automated Attack Pattern detection capabilities that could help prevent, stop, or remediate an attack. Keep an eye out for more innovations around this initiative. And download our ebook, The Need to Focus on the Adversary, to learn why understanding the attacker is important. Intelligence Channels: Security teams are under pressure to do more with less. Unfortunately, most organizations need help effectively implementing threat intelligence, not benefiting from the value their threat intelligence team, processes, and tools provide. We’ve made it easier for Security teams to implement out-of-the-box tailored intelligence with Intelligence Channels. Intelligence Channels are for organizations that need help implementing threat intelligence. Curated by The Anomali | Malware Threat | ★ | |

Babuk Ransomware Variant in Major New Attack
(published: December 7, 2022)
In November 2022, Morphisec researchers identified a new ransomware variant based on the Babuk source code that was leaked in 2021. One modification is lowering detection by abusing the legitimate Microsoft signed process: DLL side-loading into NTSD.exe — a Symbolic Debugger tool for Windows. The mechanism to remove the available Shadow Copies was changed to using Component Object Model objects that execute Windows Management Instrumentation queries. This sample was detected in a large, unnamed manufacturing company where attackers had network access and were gathering information for two weeks. They have compromised the company’s domain controller and used it to distribute ransomware to all devices within the organization through Group Policy Object. The delivered BAT script bypasses User Account Control and executes a malicious MSI file that contains files for DLL side-loading and an open-source-based reflective loader (OCS files).
Analyst Comment: The attackers strive to improve their evasion techniques, their malware on certain steps hides behind Microsoft-signed processes and exists primarily in device memory. It increases the need for the defense-in-depth approach and robust monitoring of your organization domain.

2022-12-08 19:03:00 | Why Understanding Your Attack Surface is Imperative (lien direct) | We live in a world of constant change. Digital transformation has fundamentally changed the way we work, play, learn, shop, travel, communicate, connect, collaborate, create, consume media, earn income, and even sleep. These changes have brought about new risks, challenges, and opportunities for innovation, efficiency, and growth. As the pace of change accelerates, organizations must adapt their business models, processes, and technologies to remain competitive. Digital transformation isn’t just about moving to the cloud, adopting new technologies, or building better apps. It’s also about protecting those investments and ensuring they’re protected from the beginning. This means taking a holistic approach to cybersecurity, including addressing the entire attack chain from end to end. To do so, organizations need to leverage technology to improve operational efficiencies while ensuring security and compliance. But doing so requires them to rethink many aspects of their current operations — including their network architecture, application development lifecycle, data center design, and cybersecurity strategy. Increasing Concerns and Challenges With the rapid expansion of cloud computing, mobile devices, social networking, big data analytics, and virtualized environments such as private clouds, public clouds, and hybrid clouds, enterprises now face significant challenges in managing all the various components involved in their IT infrastructure. They are forced to reevaluate their existing approaches to manage their networks, servers, applications, storage systems, and endpoints. And yet, despite the growing complexity, plenty of things still need to be clarified about the required solutions and how to deploy them efficiently. In addition to the traditional concerns regarding performance, availability, scalability, reliability, and security, organizations must consider the effects of digital transformation on their physical environment. For instance, as companies move toward using software-defined everything (SDX), the attack surface expands exponentially. Even if a company has a robust SDN solution, it may not be enough to protect itself from an advanced persistent threat (APT) or a targeted attack. There are many ways to classify APTs, but they share one common characteristic — they are highly targeted, stealthy, and extremely effective. Cyber Attacks and Attackers Evolving Today’s sophisticated attackers can exploit vulnerabilities in any aspect of the organization’s IT infrastructure, whether it’s a desktop operating system, server, router, firewall, VPN gateway, endpoint device, or cloud provider. A successful attacker could compromise an employee’s computer, gain access to sensitive corporate files, steal intellectual property, destroy critical production assets, disrupt operations, or cause catastrophic damage. As the number of connected devices continues to grow, the sophistication of cyber attacks targeting these devices is increasing. Advanced persistent threats are often referred to as “one-stop shops” because they simultaneously aim at multiple targets. Many APTs operate continuously without ever stopping to download updates or install patches. Defining Your Attack Surface Attack surfaces are comprised of all the technology that exists inside an organization. This includes computers, mobile devices, applications, networks, operating systems, browsers, network infrastructure, cloud computing platforms, email servers, databases, storage, and many others. Attack surfaces represent the potential vulnerabilities that could allow attackers to gain unauthorized access to internal resources and data. For example, a typical company might use a combination of Microsoft Windows XP, OS X 10.7 Lion, iOS 5.0, and WebKit browser versions 4.0 - 6.0. Each of these components represents a point of entry for malicious code, including viruses, spyware, Trojans, worms, expl | Vulnerability Threat | ★★★ | |

Chinese Gambling Spam Targets World Cup Keywords
(published: December 2, 2022)
Since 2018, a large-scale website infection campaign was affecting up to over 100,000 sites at a given moment. Infected websites, mostly oriented at audiences in China, were modified with additional scripts. Compromised websites were made to redirect users to Chinese gambling sites. Title and Meta tags on the compromised websites were changed to display keywords that the attackers had chosen to abuse search engine optimization (SEO). At the same time, additional scripts were switching the page titles back to the original if the visitor fingerprinting did not show a Chinese search engine from a preset list (such as Baidu).
Analyst Comment: Website owners should keep their systems updated, use unique strong passwords and introduce MFA for all privileged or internet facing resources, and employ server-side scanning to detect unauthorized malicious content. Implement secure storage for website backups.

Voice-Scamming Site “iSpoof” Seized, 100s Arrested in Massive Crackdown
(published: November 25, 2022)
iSpoof was a threat group offering spoofing for caller phone numbers (also known as Caller ID, Calling Line Identification). iSpoof core group operated out of the UK with presence in other countries. In the 12 months until August 2022 around 10 million fraudulent calls were made globally via iSpoof. On November 24, 2022, Europol announced a joint operation involving Australia, Canada, France, Germany, Ireland, Lithuania, Netherlands, Ukraine, the UK, and the USA, that led to the arrest of 142 suspects and seizure of iSpoof websites.
Analyst Comment: Threat actors can spoof Caller ID (Calling Line Identification) similar to spoofing the “From:” header in an email. If contacted by an organization you should not confirm any details about yourself, take the caller’s details, disconnect and initiate a call back to the organization yourself using a trusted number. Legitimate organizations understand scams and fraud and do not engage in unsolicited calling.

New Ransomware Attacks in Ukraine Linked to Russian Sandworm Hackers
(published: November 25, 2022)
On November 21, 2022, multiple organizations in Ukraine were targeted with new ransomware written in .NET. It was dubbed RansomBoggs by ESET researchers who attributed it to the Russia-sponsored Sandworm Team (aka Iridium, BlackEnergy). Sandworm distributed RansomBoggs from the domain controller using the same PowerShell script (PowerGap) that was seen in its previous attacks. RansomBoggs encrypts files using AES-256 in CBC mode using a randomly generated key. The key is RSA encrypted prior to storage and the encrypted files are appended with a .chsch extension.
Analyst Comment: Ransomware remains one of the most dangerous types of malware threats and even some government-sponsored groups are using it. Sandworm is a very competent actor group specializing in these forms of attack. Organizations with exposure to the military conflict in Ukraine, or considered by the Russian state to be providing support relating to the conflict, should prepare offline backups to minimize the effects of a potential data-availability-denial attack.

DEV-0569 Finds New Ways to Deliver Royal Ransomware, Various Payloads
(published: November 17, 2022)
From August to October, 2022, Microsoft researchers detected new campaigns by a threat group dubbed DEV-0569. For delivery, the group alternated between delivering malicious links by abusing Google Ads for malvertising and by using contact forms on targeted organizations’ public websites. Fake installer files were hosted on typosquatted domains or legitimate repositories (GitHub, OneDrive). First stage was user-downloaded, signed MSI or VHD file (BatLoader malware), leading to second stage payloads such as BumbleBee, Gozi, Royal Ransomware, or Vidar Stealer.
Analyst Comment: DEV-0569 is a dangerous group for its abuse of legitimate services and legitimate certificates. Organizations should consider educating and limiting their users regarding software installation options. Links from alternative incoming messaging such as from contact forms should be treated as thorough as links from incoming email traffic.

2022-11-17 14:35:00 | Gartner Insights: How to Respond to the Cyberthreat Landscape (lien direct) | The digital transformation era has fundamentally changed how organizations operate, including how they manage information technology processes and systems. This change has been driven primarily by a desire to improve efficiency, reduce costs, and increase agility across multiple business areas. These changes are often accompanied by a shift from traditional physical environments to fully virtualized ones. While the benefits of virtualization are well documented, the adoption of virtualization leads to the creation of highly vulnerable network architecture, especially when combined with public cloud resources. The risk of cyberattacks is increasing across industries, impacting every aspect of modern life. This includes everything from financial institutions to healthcare providers, manufacturing companies to retail stores, government agencies to educational institutions, energy utilities to transportation systems, telecommunications carriers to media outlets, and many others. Gartner Cybersecurity Research In fact, according to Gartner, nearly 90% of large enterprises now face some form of cyberattack each month. And among those attacks, 40% are considered high severity. In addition, there are over 3,200 known malware families, ranging from simple viruses to sophisticated targeted attacks. Gartner found that most organizations understand the importance of addressing cybercrime, but only some know how to do it properly. They believe cybersecurity must address technology and people issues, but they don’t fully realize how much of a challenge this truly is. Gartner’s research found that the current cybersecurity approach is failing, and a shift is needed. The research recommends that organizations take a holistic view of the problem and ensure proper alignment of security to top emerging threats by: • Gaining a clear picture of the current state of play: What are the biggest threats facing companies today? Where do they lie within the context of the overall threat landscape? And can you identify the threats? • Understanding where the most significant risk lies: Which areas pose the greatest threat to businesses today? And why? • Implementing effective strategies for mitigating threats: What are effective ways to address the most significant threats? For example, what types of technologies can help protect against data breaches? And how do you protect against insider threats? Or secure cloud environments? Post-Covid Era Cybersecurity Even though we’re now past the COVID-19 crisis, there were many disruptions in the cybersecurity industry. Many large companies continue to focus on remote work, causing cloud-based operations to increase and expanding 5G networks connected devices at faster speeds and greater bandwidths. Cryptocurrencies exploded in popularity and are now bought, sold, and traded by individuals on a grander scale than ever before. Many organizations need more visibility into the full extent of the risks across their growing attack surface, making it challenging to identify and address vulnerabilities effectively. In addition, the rapid pace of innovation and sophistication in attacks makes it increasingly challenging for organizations to keep up with new threats. Organizations must ensure they have the right solutions, like a threat intelligence management or extended detection and response (XDR) platform, to defend against cyberattacks proactively. Cyber Attacks and Attackers are Evolving The stereotypical hacker working alone is no longer the main threat. Today’s attackers are more methodological and work within larger teams of individuals, often organized into hacking collectives known as advanced persistent threats (APTs).

Massive ois[.]is Black Hat Redirect Malware Campaign
(published: November 9, 2022)
Since September 2022, a new WordPress malware redirects website visitors via ois[.]is. To conceal itself from administrators, the redirect will not occur if the wordpress_logged_in cookie is present, or if the current page is wp-login.php. The malware infects .php files it finds – on average over 100 files infected per website. A .png image file is initiating a redirect using the window.location.href function to redirect to a Google search result URL of a spam domain of actors’ choice. Sucuri researchers estimate 15,000 affected websites that were redirecting visitors to fake Q&A sites.
Analyst Comment: WordPress site administrators should keep their systems updated and secure the wp-admin administrator panel with 2FA or other access restrictions. If your site was infected, perform a core file integrity check, query for any files containing the same injection, and check any recently modified or added files.

2022-11-10 11:49:00 | The Need for More Data in Security Operations (lien direct) | The increasing reliance on big data has created a broader scope for hackers to exploit. But, it’s also made opportunities for cybersecurity professionals to help identify threats. Recent ESG research found that survey respondents want to use more data for security operations, driving the need for scalable, high-performance, cloud-based back-end data repositories. The research found that 80% of organizations use more than 10 data sources as part of security operations to detect malicious activities, believing the most important to be: endpoint security data, threat intelligence feeds, security device logs, cloud security data, and network flow logs. While these are all valuable in their own right, they can also be difficult to collect, store, analyze, and correlate across multiple systems. Big data analytics has made it possible for organizations to combine multiple sources of information into one unified view of an event or incident. Though there have been advanced, many security tools still lack the ability to integrate, especially if they are from multiple vendors. This makes sharing information harder and highlights the need for better integration between telemetry sources and analysis tools. Challenges with Big Data There is no shortage of hype surrounding big data. Many companies are already reaping the benefits of big data and applying it to improve their operations. Big data is often described as “dense,” meaning that it contains a lot of information and is hard to analyze. While this makes it easier to collect, it also challenges organizations to figure out what information is relevant and how to apply it. The same goes for cybersecurity threats. There is a lot of buzz about the potential of big data to help identify attackers, but the reality is that it doesn’t just work like that. Instead, big data also provides a way for attackers to hide within vast amounts of information. They can further exploit this to avoid detection and even change their identity multiple times before unleashing a cyber attack. Using Data for Cybersecurity Even though data is the most appetizing and easily accessible target for attackers, that doesn’t mean you shouldn’t collect and analyze it. Data analysis can provide insights into how attackers target your organization for a cyber attack and what they might do next. According to the ESG Research, SOC teams collect, process, and analyze a variety of security telemetry to help them determine detection weaknesses where custom rules are needed. Security teams customize vendor rule sets to meet their needs and develop custom rules to detect threats targeting their industry or organization. Data Visualization & Analytics Big data analytics allows an organization to visualize attacks, detect anomalies, and discover relationships between different data sets. Machine Learning & Predictive Modeling Machine learning helps identify potential threats and behavior patterns by analyzing the data collected during the attack and comparing it with patterns we know about. We can even build predictive models based on our experience to detect similar attacks in the future. Security Controls Automation Artificial intelligence can help quickly automate threat intelligence to security controls to protect against security breaches. For example, machine learning could help identify activities related to a particular type of event and block access to those actions or events. The Need to Understand the Attacker Threat actors use three main attack vectors: social engineering, malware, and brute force. Social engineering occurs when someone attempts to trick another person into disclosing confidential information or giving up control | Malware Vulnerability Threat | ||

2022-11-08 22:09:00 | Modernize Your Security Operations & Reduce Cost (lien direct) | “Anomali delivers a breakthrough to the alphabet soup of SIEM, SOAR, Intelligence & XDR at a fraction of the cost” Doing Business Today In good or tough macroeconomic environments, security efficacy should be delivered with efficiency and a positive impact on earnings per share. CIOs and CISOs tell us that their overarching deliverable is to amplify the visibility of their security controls and enrich the visibility with actioned context to stop adversaries and attackers. Easier said than done due to the scale and performance of the underlying technology and because the cost to deliver optimal visibility has been simply inhibitive. Security operations are growing more complex and need to be modernized while rationalizing cost. The Anomali Platform delivers breakthrough levels of security visibility use cases while lowering cost and then applying the best democratized actioned intelligence to stop the adversaries —with automation at the heart of everything that we do. Our breakthrough is your consolidation and optimization of the alphabet soup of SIEM, SOAR, Intelligence, XDR, and the next-generation versions of the same. Indebted to my partner and founder Hugh Njemanze (aka Silicon Valley’s father of SIEM and Visibility) for tirelessly evolving and optimizing our vision to help our customers and the broader community of peers and partners beat the bad guys. Background Security operations are challenged with talent scarcity and rising costs to deal with a changing threat landscape (including ransomware), growing (often uncontrolled) attack surface, higher volume and complexity of security alerts, growing adoption of public cloud services, and keeping up with their business challenges in a more digital world. CIOs and CISOs have appropriately invested in comprehensive security controls (Endpoint, Network, Cloud, Email, Identity, Patching, etc.) and yet lack orchestrated visibility across the stack with the necessary forensic lookback (up to seven years in some cases). Most of the security controls do not talk to each other and along with growing cloud logs results in mega growth of telemetry terabytes. To date, the technology that attempts to solve the big data problem traverses the alphabet soup of SIEM, SOAR, Intelligence, XDR, and the next-generation versions of the same. The challenge continues to be scale, performance, and democratized actioned intelligence. And it is just too costly. Hugh Njemanze long ago declared: “Visibility is crucial to the digitized enterprise. Back in the day, we started ArcSight to help address that problem with telemetry. Years later, despite the advent of next-gen SIEMs, SOARs, and various claims to XDR, it is still not commercially feasible to attain full visibility. That is the first step required in security operations and it is simply inhibited by cost. At Anomali, we ingest all telemetries and with proprietary technology, we do it at an affordable cost. This is essential to empowering modern businesses to unlock their true potential and what I had in mind in building the first SIEM.” Solution: Modernize and Scale at a Lower Cost At Anomali, we help our customers modernize their security operations by building a scalable foundation to deliver better and more relevant visibility while orchestrating and automating the rest of the security tech stack. We also help our customers move from a reactive baseline to a more proactive delivery of security. Some of our long-time XDR customers are now using The Anomali Platform to drive broader business insights. It’s an infinite game and we will continue building the latest innovations in cloud, AI and ML, big data, intelligence, and automation. Given the economic and geo-political challenges, we are working tirelessly with our customers to modernize their security operations with an emphasis on reducing their costs. We have | Threat | ||

Cobalt Strike Analysis and Tutorial: Identifying Beacon Team Servers in the Wild
(published: November 3, 2022)
Cobalt Strike remains a popular post-exploitation tool for threat actors trying to evade threat detection. Cobalt Strike’s Beacons use advanced, flexible command-and-control (C2) communication profiles for stealth communication with an attacker-controlled Linux application called Team Server. Beacon implants can covertly utilize the DNS protocol or communicate via HTTP/HTTPs using the the default Malleable C2 profile or Malleable C2 Gmail profile. Palo Alto researchers probed the Internet for these three types of communication to find previously-unknown active Team Server instances. Researchers were preselecting suspicious IP addresses with Shodan, actively probing them with stager requests and initializing a connection with the netcat tool to test, verify and extract communication profile settings (such as the served stager bytes).
Analyst Comment: Network fingerprinting and active scanning technologies allow for proactive identification of threats such as Cobalt Strike’s C2 IP addresses. Network defenders and intelligence feed providers can get better coverage by improving their collaboration and coverage via threat intelligence platforms such as ThreatStream provided by Anomali.

Abusing Microsoft Customer Voice to Send Phishing Links
(published: November 3, 2022)
Avanan researchers detected a phishing campaign that abuses Microsoft Dynamics 365 Customer Voice since at least September 2022. These phishing emails come from legitimate email address surveys@email.formspro.microsoft.com, and clicking the link opens the Microsoft’s Customer Voice domain on a page with URL starting with: customervoice.microsoft.com/Pages/ResponsePage.aspx?id=... At the same time, a user clicking on the embedded “Play Voicemail” link redirects to an attacker-controlled phishing page asking for Microsoft account login credentials.
Analyst Comment: Organizations can use services like Anomali Digital Risk Protection, which defends your brand against brand abuse and continuously monitors domains for cybersquatters and domain hijacking to prevent phishing and malware attacks. Users are advised to always check the current domain by hovering over the URL, especially before entering credentials.

Threat Analysis: Active C2 Discovery Using Protocol Emulation Part3 (ShadowPad)
(published: October 27, 2022)
ShadowPad is a custom, modular malware in use by multiple China-sponsored groups since 2015. VMware researchers analyzed the command-and-control (C2) protocol in recent ShadowPad samples. They uncovered decoding routines and protocol/port combinations such as HTTP/80, HTTP/443, TCP/443, UDP/53, and UDP/443. Active probing revealed 83 likely ShadowPad C2 servers (during September 2021 to September 2022). Additional samples communicating with this infrastructure included Spyder (used by APT41) and ReverseWindow (used by the LuoYu group).
Analyst Comment: Researchers can use reverse engineering and active probing to map malicious C2 infrastructure. At the same time, the ShadowPad malware changes the immediate values used in the packet encoding per variant, so finding new samples is crucial for this monitoring.

Raspberry Robin Worm Part of Larger Ecosystem Facilitating Pre-Ransomware Activity
(published: October 27, 2022)
The Raspberry Robin USB-drive-targeting worm is an increasingly popular infection and delivery method. Raspberry Robin works as a three-file infection: Raspberry Robin LNK file on an USB drive, Raspberry Robin DLL (aka Roshtyak) backdoor, and a heavily-obfuscated .NET DLL that writes LNKs to USB drives. Microsoft researchers analyzed several infection chains likely centered around threat group EvilCorp (aka DEV-0206/DEV-0243). Besides being the initial infection vector, Raspberry Robin was seen delivered by the Fauppod malware, which shares certain code similarities both with Raspberry Robin and with EvilCorp’s Dridex malware. Fauppod/Raspberry Robin infections were followed by additional malware (Bumblebee, Cobalt Strike, IcedID, TrueBot), and eventually led to a ransomware infection (LockBit, Clop).
Analyst Comment: Organizations are advised against enabling Autorun of removable media on Windows by default, as it allows automated activation of an inserted, Raspberry Robin-infected USB drive. Apply best practices related to credential hygiene, network segmentation, and attack surface reduction.

2022-10-26 18:31:00 | Accelerating Security Resilience at a Fraction of the Cost (lien direct) | Manage security in the current macro and help increase business revenue and EPS with a scalable SOC
IMAGINE accelerating security resilience at a fraction of the cost – an operating foundation at scale to change how we play the infinite game of cybersecurity and even shift the security cost to the bad guys.
Muhammed Ali was not the strongest and toughest boxer – he owned the middle of the ring, using his speed to play the infinite and shift the hard work to his adversaries – he was the greatest.
Elevating Security Resilience requires focused visibility to deliver the punches – the underlying foundation must be automated to keep up with scale at a fraction of the cost.
The popular mantra says, “every business is a digital business; you’re digital, or you’re dead.” This could not be truer in today’s world. While digital transformation has been an ongoing trend, Covid-19 accelerated that transformation beyond normal. Companies transformed their digital processes 20-25[1] times faster than before due to the onset of the pandemic. The changes included customer interactions, employee engagement, back-office processes, supply chain, and more. It’s a cliché to state that cyber becomes a core business risk as businesses get more digitally connected. Scan the SEC filings of any publicly listed company, and it’s amply clear that digital transformation unlocks massive growth but also expands the risk profile for most organizations. Cyber resilience is business resilience. The corollary holds equally true – cyber fragility impedes business growth.
 Figure 1: Digital transformation & cyber risk
The traditional approach to cybersecurity has focused on a tech-centric approach to security, evolving a technology acronym soup, continuously trying to find the smarter tool to speed up and scale security operations. This approach, somewhat successful at the lower levels of digital transformation, has become unmanageable and incredibly expensive for businesses. In spending time with board directors, management teams, CIOs, and CISOs, we’ve realized that there is a dire need to pause and reset the foundational thinking with an eye on more effective delivery that can scale at a manageable cost.
When an attacker targets an organization, they start by first conducting reconnaissance and understanding a company’s business model, profile, and strategy. Security needs to focus on the WHY - the business context. Why are they an interesting target, and what can they do to deter the attackers? This fusion of business context with security is critical to transforming security for the modern enterprise and helping executives answer key questions on business risk and resilience.
As Einstein aptly said, “we cannot solve our problems with the same thinking we used to create them.”
Sprucing up Security Operations
A recent ESG survey highlighted that 52% of security professionals consider security today more complex today than two years ago[2]. There are several drivers for this, including changing threat landscape, growing attack surface, higher volume and complexity of security alerts, growing adoption of public cloud services, keeping up with operational needs of SecOps technologies, and collecting and growing more data.
Elevating security necessitates a step back first to understand the goal.

2022-10-20 13:36:00 | Threat Hunting: Eight Tactics to Accelerating Threat Hunting (lien direct) | One of the more significant headaches in cyber security is the overuse of buzzwords and acronyms and the overlapping mutations of what they mean. Cyber threat Hunting has become one of those phrases, but it has gained clarity over the last few years as organizations strived to become more proactive. So what is threat hunting? Depending on who you ask, you may get somewhat different answers to the same question. Cyber threat hunting is a proactive approach to detecting suspicious activity from known or unknown, remediated, or unaddressed cyber threats within an organization’s networks. It involves finding malware such as viruses, Trojans, adware, spyware, ransomware, worms, bots, and botnets. The goal is for security analysts to find these threats before they cause damage to systems and data. It’s similar to how fire departments respond to fires; they go into buildings to ensure no additional problems before calling the firefighters. There is a vast collection of tools, skill sets, approaches, and processes to help identify advanced threats that could happen within the network. What is an effective hunting process for one organization may be a waste of time for another, depending on each company’s understanding of what threats they might face. Man-hours spent hunting are typically most beneficial for large organizations targeted by the cybercriminal community regularly, but that’s not to say that regular hunts for small/medium-sized enterprises can’t benefit from and identify threats by doing the same. Structured Threat Hunting The structured hunt is based on indicators of compromise (IOCs) and tactics, techniques, and procedures (TTP). IOCs provide information about potential adversaries, such as IP addresses, domain names, operating system versions, etc. TTPs describe how attackers operate and what tools they use. Combining IOCs and TTPs makes it possible to build a picture of the adversary. This approach allows us to detect threats earlier and prevent attacks. In addition, we can quickly identify the threat actors because each activity is described in detail. Unstructured Threat Hunting The concept of unstructured hunting is relatively new. It wasn’t until 2013 that we began seeing the emergence of unstructured hunters. Unstructured hunting is a method of finding malicious software (malware), such as viruses, Trojans, worms, etc., without knowing exactly what type of malware you are looking for. Instead, the hunter relies on behavioral analysis to find these threats. In short, unstructured hunting is investigative work where a cyber threat hunter observes behavior and looks for anomalies. For example, if someone sends out spam emails, a system administrator might notice unusual activity on his network and investigate further. If he finds something suspicious, he could take action immediately or wait a few days to see if the same email addresses start sending again. Traditional Threat Hunting The traditional definition of threat hunting can be defined as a focused and intensive human/machine-assisted process aimed to identify the possibility of something malicious happening within the network or likely about to happen; this is based on abnormal network behavior, artifacts, or identification via active threat research. A good example of this would be: A large bank has team members whose part of their job is to consume threat reports related to activity targeting their vertical and other companies that match their Enterprise profile. > A new threat report is published from an intel provider describing a new variant of malware that has been catastrophic at similar organizations. This report would ideally contain information around the process tree, registry key, etc., to help the cyber threat hunters not just hunt for detection of the associated IOCs but dig deeper to identify patterns that match the behavior of the malware across the network, like abnormal PowerShell executio | Spam Malware Tool Vulnerability Threat | ||

Ransom Cartel Ransomware: A Possible Connection With REvil
(published: October 14, 2022)
Palo Alto Networks researchers analyzed Ransom Cartel, a double extortion ransomware-as-a-service group. Ransom Cartel came to existence in mid-December 2021 after the REvil group shut down. The Ransom Cartel group uses the Ransom Cartel ransomware, which shares significant code similarities with REvil, indicating close connections, but lacks REvil obfuscation engine capabilities. Ransom Cartel has almost no obfuscation outside of the configuration: unlike REvil it does not use string encryption and API hashing. Among multiple tools utilized by Ransom Cartel, the DonPAPI credential dumper is unique for this group. It performs Windows Data Protection API (DPAPI) dumping by targeting DPAPI-protected credentials such as credentials saved in web browsers, RDP passwords, and Wi-Fi keys.
Analyst Comment: Network defenders should consider monitoring or blocking high-risk connections such as TOR traffic that is often abused by Ransom Cartel and its affiliates. It is crucial that your company ensure that servers are always running the most current software version. Your company should have policies in place in regards to the proper configurations needed for your servers in order to conduct your business needs safely.

We encourage each of you to engage in this year’s efforts by creating your own cyber awareness campaigns and sharing this messaging with your peers.” -Cybersecurity and Infrastructure Security Agency (CISA) Cybersecurity is Complex See Yourself in Cyber can be interpreted in multiple ways. To me, it’s speaking to those students unsure of what to major in, telling them to see themselves working in the industry. It’s reaching out to other departments within an organization to get them to understand how they impact security. And highlighting how hard a security analyst’s job is. In a recent blog post, I dove deeper into why security is more challenging than ever. And it all comes back to people. People are the heart of any security organization. Security tools are a requirement, but they don’t replace people. According to (ISC) ²’s 2021 Cyber Workforce Report, there is still a cybersecurity workforce gap of more than 2.72 million. Which for some organizations can mean they’re already behind before even starting. Improving Your Security Posture There are many ways an organization can improve its security posture. They can share threat intelligence. They can invest in threat intelligence platforms or XDR solutions that improve their existing investments. For this blog, I’ve narrowed it down to five: 1) Understanding Your Relevant Threat Landscape Understanding the attack surface is key to knowing what assets need protection and how best to protect them. Unfortunately, most organizations struggle because their attack surface keeps changing. Start with an attack surface assessment. Find out how an attacker sees you. Map your assets against their potential vulnerabilities and readiness to prevent or respond to threats. This will help understand how well current tools and investments protect critical assets and what additional measures need to be taken to improve protection. A comprehensive assessment should include the following: • Visibility into all external facing assets to uncover exposed assets • Identify and evaluate the current security programs • Evaluate the effectiveness of information security policies, procedures, and processes • Determine the effect of cybersecurity incidents on KPIs, including availability, integrity, and privacy • Assess the maturity level of current tools and investments | Ransomware Malware Hack Threat Guideline |
