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.

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.

First-Ever Attack Leveraging Kubernetes RBAC to Backdoor Clusters
(published: April 21, 2023)
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.

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.

#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.

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.

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.

Turla: A Galaxy of Opportunity
(published: January 5, 2023)
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).

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.

On November 30, 2022, Google reported 10 different Android platform certificates that were seen actively abused in the wild to sign malware. Rapid7 researchers found that the reported signed samples are adware, so it is possible that these platform certificates may have been widely available. It is not shared how these platform certificates could have been leaked.
Analyst Comment: Malware signed with a platform certificate can enjoy privileged execution with system permissions, including permissions to access user data. Developers should minimize the number of applications requiring a platform certificate signature.

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.

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.

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.

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.

Alert (AA22-294A) #StopRansomware: Daixin Team
(published: October 21, 2022)
Daixin Team is a double-extortion ransomware group that has been targeting US businesses, predominantly in the healthcare sector. Since June 2022, Daixin Team has been encrypting electronic health record services, diagnostics services, imaging services, and intranet services. The group has exfiltrated personal identifiable information and patient health information. Typical intrusion starts with initial access through virtual private network (VPN) servers gained by exploitation or valid credentials derived from prior phishing. They use SSH and RDP for lateral movement and target VMware ESXi systems with ransomware based on leaked Babuk Locker source code.
Analyst Comment: Network defenders should keep organization’s VPN servers up-to-date on security updates. Enable multifactor authentication (MFA) on your VPN server and other critical accounts (administrative, backup-related, and webmail).

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.

VMware Report Exposes Emotet Malware’s Supply Chain
(published: October 10, 2022)
VMware researchers analyzed the Emotet malware-as-a-service evolution and its command-and-control (C2) infrastructure. In June 2022, Emotet added two new modules: one stealing credit card information from Google Chrome browsers, and another one that leverages the SMB protocol to spread laterally. Emotet’s main component is a DLL file that stores a highly obfuscated list of C2 IP:port pairs. More than half of the ports counted were port 8080 used as a proxy port on compromised legitimate servers abused to proxy traffic to the real C2 servers.

LofyGang Hackers Built a Credential-Stealing Enterprise on Discord, NPM
(published: October 7, 2022)
Checkmarx Security researchers described a financially-motivated threat actor group dubbed LofyGang (Lofy). This group aims at stealing credentials and credit card data by distributing approximately 200 malicious packages and fake hacking tools on code-hosting platforms, such as NPM and GitHub. LofyGang uses package name typosquatting and the starjacking technique of displaying fake popularity statistics. The first LofyGang package typically does not have a malicious behavior besides getting the second-stage malicious package. For its command-and-control communication the group often abuses legitimate services such as Discord, GitHub, glitch, Heroku, and Repl.it.

New Royal Ransomware Emerges in Multi-Million Dollar Attacks
(published: September 29, 2022)
AdvIntel and BleepingComputer researchers describe the Royal ransomware group. Several experienced ransomware actors formed this group in January 2022. It started with third-party encryptors such as BlackCat, switched to using its own custom Zeon ransomware, and, since the middle of September 2022, the Royal ransomware. Royal group utilizes targeted callback phishing attacks. Its phishing emails impersonating food delivery and software providers contained phone numbers to cancel the alleged subscription (after the alleged end of a free trial). If an employee calls the number, Royal uses social engineering to convince the victim to install a remote access tool, which is used to gain initial access to the corporate network.
Analyst Comment: Use services such as Anomali's Premium Digital Risk Protection to detect the abuse of your brands in typosquatting and phishing attacks. Organizations should include callback phishing attacks awareness into their anti-phishing training.

ZINC Weaponizing Open-Source Software
(published: September 29, 2022)
Microsoft researchers described recent developments in Lazarus Group (ZINC) campaigns that start from social engineering conversations on LinkedIn. Since June 2022, Lazarus was able to trojanize several open-source tools (KiTTY, muPDF/Subliminal Recording software installer, PuTTY, TightVNC, and Sumatra PDF Reader). When a target extracts the trojanized tool from the ISO file and installs it, Lazarus is able to deliver their custom malware such as EventHorizon and ZetaNile. In many cases, the final payload was not delivered unless the target manually established an SSH connection to an attacker-controlled IP address provided in the attached ReadMe.txt file.
Analyst Comment: All known indicators connected to this recent Lazarus Group campaign are available in the Anomali platform and customers are advised to block these on their infrastructure. Researchers should monitor for the additional User Execution step required for payload delivery. Defense contractors should be aware of advanced social engineering efforts abusing LinkedIn and other means of establishing trusted communication.

A Multimillion Dollar Global Online Credit Card Scam Uncovered
(published: September 23, 2022)
ReasonLabs researchers discovered a large network of fake dating and customer support websites involved in credit card fraud operations. The threat actor builds a basic website, registers it with a payment processor (RocketGate), buys credit card data from other threat actors, and subscribes victims to monthly charging plans. The US was the most targeted, and a lower number of sites were targeting France. To pass the processor checks and lower the number of charge-backs the actor avoided test charges, used a generic billing name, charged only a small, typical for the industry payment, and hired a legitimate support center provider, providing effortless canceling and returning of the payment.
Analyst Comment: Users are advised to regularly check their bank statements and dispute fraudulent charges. Researchers can identify a fraudulent website by overwhelming dominance of direct-traffic visitors from a single country, small network of fake profiles, and physical address typed on a picture to avoid indexing.

Malicious OAuth Applications Used to Compromise Email Servers and Spread Spam
(published: September 22, 2022)
Microsoft researchers described a relatively stealthy abuse of a compromised Exchange server used to send fraud spam emails. After using valid credentials to get access, the actor deployed a malicious OAuth application, gave it admin privileges and used it to change Exchange settings. The first modification created a new inbound connector allowing mails from certain actor IPs to flow through the victim’s Exchange server and look like they originated from the compromised Exchange domain. Second, 12 new transport rules were set to delete certain anti-spam email headers.
Analyst Comment: If you manage an Exchange server, strengthen account credentials and enable multifactor authentication. Investigate if receiving alerts regarding suspicious email sending and removal of antispam header.

Hacker Pwns Uber Via Compromised VPN Account
(published: September 16, 2022)
On September 15, 2022, ride-sharing giant Uber started an incident response after discovering a data breach. According to Group-IB researchers, download file name artifacts point to the attacker getting access to fresh keylogger logs affecting two Uber employees from Indonesia and Brazil that have been infected with Racoon and Vidar stealers. The attacker allegedly used a compromised VPN account credentials and performed multifactor authentication fatigue attack by requesting the MFA push notification many times and then making a social-engineering call to the affected employee. Once inside, the attacker allegedly found valid credentials for privilege escalation: a PowerShell script containing hardcoded credentials for a Thycotic privileged access management admin account. On September 18, 2022, Rockstar Games’ Grand Theft Auto 6 suffered a confirmed data leak, likely caused by the same attacker.
Analyst Comment: Network defenders can consider setting up alerts for signs of an MFA fatigue attack such as a large number of MFA requests in a relatively short period of time. Review your source code for embedded credentials, especially those with administrative privileges.

Microsoft Investigates Iranian Attacks Against the Albanian Government
(published: September 8, 2022)
Microsoft researchers discovered that groups working under Iran’s Ministry of Intelligence and Security (MOIS, tracked as OilRig) attacked the government of Albania. The attackers started with initial intrusion in May 2021, proceeded with mailbox exfiltrations between October 2021 and January 2022, organized controlled leaks, and culminated on July 15, 2022, with disruptive ransomware and wiper attacks. This attack is probably a response to the June 2021 Predatory Sparrow’s anti-Iranian cyber operations promoting the Mujahedin-e Khalq (MEK), an Iranian dissident group largely based in Albania.
Analyst Comment: MOIS attack on Albania uses messaging and targeting similar to the previous MEK-associated attack on Iran. It tells us that Iran has chosen to engage in a form of direct and proportional retaliation as it sees it. Still, the attack and its attribution caused Albania to cut diplomatic ties with Iran and expel the country's embassy staff. Organizations should implement multifactor authentication (MFA) for mailbox access and remote connectivity. Anomali platform users advised to block known OilRig network indicators.

EvilProxy Phishing-As-A-Service With MFA Bypass Emerged In Dark Web
(published: September 5, 2022)
Resecurity researchers analyzed EvilProxy, a phishing kit that uses reverse proxy and cookie injection methods to bypass two-factor authentication (2FA). EvilProxy uses extensive virtual machine checks and browser fingerprinting. If the victim passes the checks, Evilproxy acts as a proxy between the victim and the legitimate site that asks for credentials. EvilProxy is being sold as a service on the dark web. Since early May 2022, Evilproxy enables phishing attacks against customer accounts of major brands such as Apple, Facebook, GoDaddy, GitHub, Google, Dropbox, Instagram, Microsoft, Twitter, Yahoo, Yandex, and others.
Analyst Comment: EvilProxy is a dangerous automation tool that enables more phishing attacks. Additionally, EvilProxy targeting GitHub and npmjs accounts increases risks of follow-up supply-chain attacks. Anomali platform has historic EvilProxy network indicators that can help when investigating incidents affecting 2FA. With 2FA bypass, users need to be aware of phishing risks and pay even more attention to domains that ask for their credentials and 2FA codes.

Cybereason researchers investigated the Ragnar Locker ransomware that was involved in cyberattack on DESFA, a Greek pipeline company. On August 19, 2022, the Ragnar Locker group listed DESFA on its data leak site. The group has been active since 2019 and it is not the first time it targets critical infrastructure companies with the double-extortion scheme. Their Ragnar Locker ransomware shows the typical abilities of modern ransomware including system information and location collection, deleting shadow copies, identifying processes (antiviruses, backup solutions, IT remote management solutions, and virtual-based software), and encrypting the system with the exception list in mind.
Analyst Comment: Ragnar Locker appears to be an aggressive ransomware group that is not shy attacking critical infrastructure as far as they are not in the Commonwealth of Independent States (Russia and associated countries). Always be on high alert while reading emails, in particular those with attachments, URL redirection, false sense of urgency or poor grammar. Use anti-spam and antivirus protection, and avoid opening email from untrusted or unverified senders. Additionally, it is important to have a comprehensive and teste |

2022-09-01 16:50:00 | Security Operations are More Difficult Now More Than Ever. Buy Why? (lien direct) | According to recent research by ESG, 52% of respondents believe security operations are more difficult today than they were two years ago. Responses stated this was due to multiple factors, such as the increasingly dangerous threat landscape, a growing attack surface, the volume and complexity of security alerts, and public cloud proliferation. Today’s threats are more sophisticated than ever, making them more challenging to defend against. Security teams must constantly do more with less, protecting more data, endpoints, and applications. And, as the threat landscape evolves, so will they, but chances are they must do so with fewer resources. The growing list of challenges is never-ending. So what tops the list? An Ever-Growing Attack Surface Organizations are collecting and storing more data than ever, driven by more cloud-based applications and services. This new on-prem/off-prem environment has created more potential entry points for attackers. Additionally, many organizations lose track of their assets, failing to update policies and their security infrastructure, leaving them vulnerable to attacks that exploit known vulnerabilities. Another reason security teams face more challenges today is the increasing number of mobile devices and cloud apps used by employees. These devices and apps can provide a convenient way for employees to access company data, but they can also be a security risk if they are not adequately secured. The Evolving Threat Landscape As the attack surface grows, so does the number of potential threats. Security teams must now contend with a broader range of threats, including sophisticated malware, zero-day exploits, and ransomware. Additionally, attackers are becoming more brazen and are targeting high-profile organizations with well-funded security operations. In addition, the rise of social media has created new opportunities for hackers to launch cyber attacks. Social media platforms can spread malware or gather information about people’s online habits, used to launch targeted attacks and infiltrate enterprise organizations. Increasing Compliance Requirements Organizations must comply with an ever-growing number of regulations, such as the EU’s General Data Protection Regulation (GDPR), that require security teams to put in place additional controls and processes, which can be costly and time-consuming. Additionally, compliance failures can result in heavy fines and strain an already tight budget. Limited Resources According to (ISC)²'s 2021 Cyber Workforce Report, the global cybersecurity workforce needs to grow 65 percent to defend organizations’ critical assets effectively. While the number of professionals required to fill the gap has decreased, the number of qualified cyber professionals will fall even further due to the growing demand for highly skilled individuals. Complex Tech Stack Enterprises frequently deploy new security tools and services to address changing needs and increased threats. As previously mentioned, a typical enterprise SOC may use a combination of twenty or more technologies, making it difficult to customize each solution for its environment. The interoperability issues caused by the possibility of using multiple vendors make it very challenging to get a complete picture of your overall security environment. The Need to Adapt Despite these challenges, security teams must find ways to adapt to protect their organizations effectively against ever-evolving threats.

LastPass Hackers Stole Source Code
(published: August 26, 2022)
In August 2022, an unidentified threat actor gained access to portions of the password management giant LastPass development environment. LastPass informed that it happened through a single compromised developer account and the attacker took portions of source code and some proprietary LastPass technical information. The company claims that this incident did not affect customer data or encrypted password vaults.
Analyst Comment: This incident doesn’t seem to have an immediate impact on LastPass users. Still, organizations relying on LastPass should raise the concern in their risk assessment since “white-box hacking” (when source code of the attacking system is known) is easier for threat actors. Organizations providing public-facing software should take maximum measures to block threat actors from their development environment and establish robust and transparent security protocols and practices with all third parties involved in their code development.

Mercury Leveraging Log4j 2 Vulnerabilities in Unpatched Systems to Target Israeli
(published: August 25, 2022)
Starting in July 2022, a new campaign by Iran-sponsored group Static Kitten (Mercury, MuddyWater) was detected targeting Israeli organizations. Microsoft researchers detected that this campaign was leveraging exploitation of Log4j 2 vulnerabilities (CVE-2021-45046 and CVE-2021-44228) in SysAid applications (IT management tools). For persistence Static Kitten was dropping webshells, creating local administrator accounts, stealing credentials, and adding their tools in the startup folders and autostart extensibility point (ASEP) registry keys. Overall the group was heavily using various open-source and built-in operating system tools: eHorus remote management software, Ligolo reverse tunneling tool, Mimikatz credential theft tool, PowerShell programs, RemCom remote service, Venom proxy tool, and Windows Management Instrumentation (WMI).
Analyst Comment: Network defenders should monitor for alerts related to web shell threats, suspicious RDP sessions, ASEP registry anomaly, and suspicious account creation. Similarly, SysAid users can monitor for webshells and abnormal processes related to SysAisServer instance. Even though Static Kitten was observed leveraging the Log4Shell vulnerabilities in the past (targeting VMware apps), most of their attacks still start with spearphishing, often from a compromised email account.

Reservations Requested: TA558 Targets Hospitality and Travel
(published: August 18, 2022)
Since 2018, financially-motivated threat group TA558 has targeted hospitality and travel with reservation-themed, business-relevant phishing emails. The group concentrates on targeting Latin America using lures written in Portuguese and Spanish, and sometimes uses English and wider targeting (North America, Western Europe). TA558 was seen leveraging at least 15 different malware payloads, most often AsyncRAT, Loda RAT, Revenge RAT, and Vjw0rm. In 2022, Proofpoint researchers detected that TA558 increased its activity and moved from using malicious macros to URLs and container files (ISO, RAR).
Analyst Comment: Microsoft’s preparations to disable macros by default in Office products caused multiple threat groups including TA558 to adopt new filetypes to deliver payloads. It is crucial for personnel working with invoices and other external attachments to use updated, secured systems and be trained on phishing threats.

Estonia Subjected to 'Extensive' Cyberattacks after Moving Soviet Monuments
(published: August 18, 2022)
On August 17, 2022, Russian hacktivist group KillNet launched distributed denial-of-service (DDoS) attacks targeting Estonia. The Estonian government confirmed receiving the “most extensive” DDoS attacks in 15 years, but stressed that all services are back online after just some minor interruptions. Small and medium-sized DDoS attacks targeted 16 state and private organizations in the country, with seven of them experiencing downtime as a result. Specifically, the Estonian Tax and Customs Board website was unavailable for about 70 minutes.
Analyst Comment: Russian cyber activity follows political tensions, this time coinciding with the removal of a Red Army memorial. Estonia seemingly easily fended off this Russian DDoS attack, but the country is one of the top in cyber preparedness, and Russia limited it’s strike to using hacktivist groups that give plausible deniability when attributing the cyber attack on a NATO country.

APT-C-35: New Windows Framework Revealed
(published: August 11, 2022)
The DoNot Team (APT-C-35) are India-sponsored actors active since at least 2016. Morphisec Labs researchers discovered a new Windows framework used by the group in its campaign targeting Pakistani government and defense departments. The attack starts with a spearphishing RTF attachment. If opened in a Microsoft Office application, it downloads a malicious remote template. After the victim enables editing (macroses) a multi-stage framework deployment starts. It includes two shellcode stages followed by main DLL that, based on victim fingerprinting, downloads a custom set of additional information-stealing modules.
Analyst Comment: The described DoNot Team framework is pretty unique in its customisation, fingerprinting, and module implementation. At the same time, the general theme of spearphishing attachment that asks the targeted user to enable editing is not new and can be mitigated by anti-phishing training and Microsoft Office settings hardening.

So RapperBot, What Ya Bruting For?
(published: August 3, 2022)
RapperBot, a new Internet of things (IoT) botnet, is rapidly evolving despite appearing in the wild just two months ago (June 2022). Fortinet researchers discovered that RapperBot heavily reuses parts of the Mirai source code, but changed the attack vector (brute-forcing SSH instead of Telnet), command and control (C2) protocol, and added persistence capabilities. RapperBot maintains remote access by adding the attacker's public key to ~/.ssh/authorized_keys. The latest RapperBot samples also started adding the root user "suhelper” to /etc/passwd and /etc/shadow/, and continue to add the root user account every hour. Top targeted IPs were from Taiwan, USA, and South Korea, in that order. RapperBot has basic DDoS capabilities such as UDP and TCP STOMP flood copied from Mirai source code.
Analyst Comment: Despite sharing a significant amount of source code with Mirai variants, RapperBot appears to be developed by a persistent actor and not a novice motivated by notoriety. It is possible that the actors will add new impact functionality after the RapperBot botnet grows substantially. SSH server administrators should adhere to secure password practices. It is also important to note that simply restarting the device, changing SSH credentials or even disabling SSH password authentication does not remove the RapperBot infection.

SharpTongue Deploys Clever Mail-Stealing Browser Extension “SHARPEXT”
(published: July 28, 2022)
Volexity researchers discovered SharpExt, a new malicious browser app used by the North-Korea sponsored Velvet Chollima (Kimsuky, SharpTongue, Thallium) group. SharpExt inspects and exfiltrates data from a victim's webmail (AOL or Gmail) account as they browse it. Velvet Chollima continues to add new features to the app, the latest known version (3.0) supports three browsers: Microsoft Edge, Google Chrome, and Whale, the latter almost exclusively used in South Korea. Following the initial compromise, Velvet Chollima deploy SharpExt and to avoid warning the victim they manually exfiltrate settings files to change the settings and generate a valid "super_mac" security check value. They also hide the newly opened DevTools window and any other warning windows such as a warning regarding extensions running in developer mode.
Analyst Comment: Velvet Chollima is known for its tactic of deploying malicious browser extensions, but in the past it was concentrating on stealing credentials instead of emails. The group continues aggressive cyberespionage campaigns exfiltrating military and industrial technologies from Europe, South Korea, and the US. Network defenders should monitor for suspicious instances of PowerShell execution, as well as for traffic to and from known Velvet Chollima infrastructure (available in Anomali Match).

Untangling KNOTWEED: European Private-Sector Offensive Actor Using 0-Day Exploits
(published: July 27, 2022)
Microsoft researchers detail activity of DSIRF, Austrian private-sector offensive actor (PSOA). In 2021, this actor, tracked as Knotweed, used four Windows and Adobe 0-day exploits. In 2022, DSIRF was exploiting another Adobe Reader vulnerability, CVE-2022-22047, which was patched in July 2022. DSIRF attacks rely on their malware toolset called Subzero. The initial downloader shellcode is executed from either the exploit chains or malicious Excel documents. It downloads a JPG image file with extra encrypted data, extracts, decrypts and loads to the memory the Corelump memory-only infostealer. For persistence, Corelump creates trojanized copies of legitimate Windows DLLs that se |
