2025-02-20 13:21:16 | (Déjà vu) Russia-Linked Actors Exploiting Signal Messenger\\'s “Linked Devices” Feature for Espionage in Ukraine (lien direct) | 
Overview
Google Threat Intelligence Group (GTIG) has identified multiple Russia-aligned threat actors actively targeting Signal Messenger accounts as part of a multi-year cyber espionage operation. The campaign, likely driven by Russia\'s intelligence-gathering objectives during its invasion of Ukraine, aims to compromise the secure communications of military personnel, politicians, journalists, and activists.
The tactics observed in this campaign include phishing attacks abusing Signal\'s linked devices feature, malicious JavaScript payloads and malware designed to steal Signal messages from compromised Android and Windows devices. While the focus remains on Ukrainian targets, the threat is expected to expand globally as adversaries refine their techniques.
Google has partnered with Signal to introduce security enhancements that mitigate these attack vectors, urging users to update to the latest versions of the app.
Tactics Used to Compromise Signal Accounts
Exploiting Signal\'s "Linked Devices" Feature
Russia-aligned threat actors have manipulated Signal\'s legitimate linked devices functionality to gain persistent access to victim accounts. By tricking users into scanning malicious QR codes, attackers can link an actor-controlled device to the victim\'s account, enabling real-time message interception without full device compromise.
The phishing methods used to deliver these malicious QR codes include:
Fake Signal group invites containing altered JavaScript redirects.
Phishing pages masquerading as Ukrainian military applications.

2025-02-11 20:00:00 | Cybercrime: A Multifaceted National Security Threat (lien direct) | Executive Summary Cybercrime makes up a majority of the malicious activity online and occupies the majority of defenders\' resources. In 2024, Mandiant Consulting responded to almost four times more intrusions conducted by financially motivated actors than state-backed intrusions. Despite this overwhelming volume, cybercrime receives much less attention from national security practitioners than the threat from state-backed groups. While the threat from state-backed hacking is rightly understood to be severe, it should not be evaluated in isolation from financially motivated intrusions. A hospital disrupted by a state-backed group using a wiper and a hospital disrupted by a financially motivated group using ransomware have the same impact on patient care. Likewise, sensitive data stolen from an organization and posted on a data leak site can be exploited by an adversary in the same way data exfiltrated in an espionage operation can be. These examples are particularly salient today, as criminals increasingly target and leak data from hospitals. Healthcare\'s share of posts on data leak sites has doubled over the past three years, even as the number of data leak sites tracked by Google Threat Intelligence Group has increased by nearly 50% year over year. The impact of these attacks mean that they must be taken seriously as a national security threat, no matter the motivation of the actors behind it. Cybercrime also facilitates state-backed hacking by allowing states to purchase cyber capabilities, or co-opt criminals to conduct state-directed operations to steal data or engage in disruption. Russia has drawn on criminal capabilities to fuel the cyber support to their war in Ukraine. GRU-linked APT44 (aka Sandworm), a unit of Russian military intelligence, has employed malware available from cybercrime communities to conduct espionage and disruptive operations in Ukraine and CIGAR (aka RomCom), a group that historically focused on cybercrime, has conducted espionage operations against the Ukrainian government since 2022. However, this is not limited to Russia. Iranian threat groups deploy ransomware to raise funds while simultaneously conducting espionage, and Chinese espionage groups often supplement their income with cybercrime. Most notably, North Korea uses state-backed groups to directly generate revenue for the regime. North Korea has heavily targeted cryptocurrencies, compromising exchanges and individual victims\' crypto wallets. Despite the overlaps in effects and collaboration with states, tackling the root causes of cybercrime requires fundamentally different solutions. Cybercrime involves collaboration between disparate groups often across borders and without respect to sovereignty. Any solution requires international cooperation by both law enforcement and intelligence agencies to track, arrest, and prosecute these criminals. Individual takedowns can have important temporary effects, but the collaborative nature of cybercrime means that the disrupted group will be quickly replaced by others offering the same service. Achieving broader success will require collaboration between countries and public and private sectors on systemic solutions such as increasing education and resilience efforts. aside_block | Ransomware Malware Tool Vulnerability Threat Legislation Medical Cloud Technical | APT 41 APT 38 APT 29 APT 43 APT 44 | ★★★ |

2025-01-31 19:21:04 | Hackers From China, North Korea, Iran & Russia Are Using Google’s AI For Cyber Ops (lien direct) | Google\'s Threat Intelligence Group (GTIG) has issued a warning regarding cybercriminals from China, Iran, Russia, and North Korea, and over a dozen other countries are using its artificial intelligence (AI) application, Gemini, to boost their hacking capabilities. According to Google\'s TIG report, published on Wednesday, state-sponsored hackers have been using the Gemini chatbot to improve their productivity in cyber espionage, phishing campaigns, and other malicious activities. Google examined Gemini activity linked to known APT (Advanced Persistent Threat) actors and discovered that APT groups from over twenty countries have been using large language models (LLMs) primarily for research, target reconnaissance, the development of malicious code, and the creation and localization of content like phishing emails. In other words, these hackers seem to primarily use Gemini as a research tool to enhance their operations rather than develop entirely new hacking methods. Currently, no hacker has successfully leveraged Gemini to develop entirely new cyberattack methods. “While AI can be a useful tool for threat actors, it is not yet the gamechanger it is sometimes portrayed to be. While we do see threat actors using generative AI to perform common tasks like troubleshooting, research, and content generation, we do not see indications of them developing novel capabilities,” Google said in its report. Google tracked this activity to more than ten Iran-backed groups, more than twenty China-backed groups, and nine North Korean-backed groups. For instance, Iranian threat actors were the biggest users of Gemini, using it for a wide range of purposes, including research on defense organizations, vulnerability research, and creating content for campaigns. In particular, the group APT42 (which accounted for over 30% of Iranian APT actors) focused on crafting phishing campaigns to target government agencies and corporations, conducting reconnaissance on defense experts and organizations, and generating content with cybersecurity themes. Chinese APT groups primarily used Gemini to conduct reconnaissance, script and develop, troubleshoot code, and research how to obtain deeper access to target networks through lateral movement, privilege escalation, data exfiltration, and detection evasion. North Korean APT hackers were observed using Gemini to support multiple phases of the attack lifecycle, including researching potential infrastructure and free hosting providers, reconnaissance on target organizations, payload development, and help with malicious scripting and evasion methods. “Of note, North Korean actors also used Gemini to draft cover letters and research jobs-activities that would likely support North Korea’s efforts to place clandestine IT workers at Western companies,” the company noted. “One North Korea-backed group utilized Gemini to draft cover letters and proposals for job descriptions, researched average salaries for specific jobs, and asked about jobs on LinkedIn. The group also used Gemini for information about overseas employee exchanges. Many of the topics would be common for anyone researching and applying for jobs.” Meanwhile, Russian APT actors demonstrated limited use of Gemini, primarily for coding tasks such as converting publicly available malware into different programming languages and incorporating encryption functions into existing code. They may have avoided using Gemini for operational security reasons, opting to stay off Western-controlled platforms to avoid monitoring their activities or using Russian-made AI tools. Google said the Russian hacking group’s use of Gemini has been relatively limited, possibly because it attempted to prevent Western platforms from monitoring its activities | Malware Tool Vulnerability Threat Legislation Cloud | APT 42 | ★★★ |

2025-01-29 14:00:00 | Adversarial Misuse of Generative AI (lien direct) | Rapid advancements in artificial intelligence (AI) are unlocking new possibilities for the way we work and accelerating innovation in science, technology, and beyond. In cybersecurity, AI is poised to transform digital defense, empowering defenders and enhancing our collective security. Large language models (LLMs) open new possibilities for defenders, from sifting through complex telemetry to secure coding, vulnerability discovery, and streamlining operations. However, some of these same AI capabilities are also available to attackers, leading to understandable anxieties about the potential for AI to be misused for malicious purposes. Much of the current discourse around cyber threat actors\' misuse of AI is confined to theoretical research. While these studies demonstrate the potential for malicious exploitation of AI, they don\'t necessarily reflect the reality of how AI is currently being used by threat actors in the wild. To bridge this gap, we are sharing a comprehensive analysis of how threat actors interacted with Google\'s AI-powered assistant, Gemini. Our analysis was grounded by the expertise of Google\'s Threat Intelligence Group (GTIG), which combines decades of experience tracking threat actors on the front lines and protecting Google, our users, and our customers from government-backed attackers, targeted 0-day exploits, coordinated information operations (IO), and serious cyber crime networks. We believe the private sector, governments, educational institutions, and other stakeholders must work together to maximize AI\'s benefits while also reducing the risks of abuse.

2024-12-30 19:16:07 | Analysis of Attack Cases Against Korean Solutions by the Andariel Group (SmallTiger) (lien direct) | ## Snapshot ASEC reports that the Andariel threat group has resumed attacks to distribute SmallTiger malware, targeting Korean software solutions, including asset management and document management tools. ## Description ASEC reports that the Andariel group (tracked by Microsoft as [Onyx Sleet](https://security.microsoft.com/intel-profiles/03ced82eecb35bdb459c47b7821b9b055d1dfa00b56dc1b06f59583bad8833c0)) exploits vulnerabilities in asset management solutions to gain control over systems. Most of these attacks resulted in the installation of ModeLoader. In one case, the attackers used [brute-force](https://security.microsoft.com/threatanalytics3/d44f2c6d-6901-4967-82b7-7ffe4f7276e7/overview) and dictionary attacks on exposed update servers to replace update programs with malicious versions, enabling them to distribute SmallTiger. In recent cases, researchers have found SmallTiger in the installation paths of asset management solutions alongside a keylogger. This keylogger stored captured keystrokes in the temporary file "MsMpLog.tmp." The attackers also configured infected systems for future Remote Desktop Protocol (RDP) access. Additionally, they deployed an open-source tool called CreateHiddenAccount to add and conceal a backdoor account. The threat group also targets document management solutions by exploiting outdated Apache Tomcat web servers. After gaining initial access, they query system information and install an Advanced Port Scanner. They then install a web shell via PowerShell commands with the download server also identified as the command-and-control server address for SmallTiger. ## Microsoft Analysis and Additional OSINT Context [Microsoft researchers determined](https://www.microsoft.com/en-us/security/blog/2024/07/25/onyx-sleet-uses-array-of-malware-to-gather-intelligence-for-north-korea/) that SmallTiger is a C++ backdoor with layered obfuscation, encountered in the wild as a Themida or VMProtect packed executable. [In February 2024](https://asec.ahnlab.com/ko/73907/), ASEC first identified SmallTiger targeting South Korean defense and manufacturing organizations. Subsequently, in May 2024, Microsoft observed Onyx Sleet conducting attacks using SmallTiger, specifically targeting South Korean defense organizations. Onyx Sleet is a North Korea-affiliated activity group that conducts cyber espionage through numerous campaigns with the goal of intelligence gathering and financial gain. The threat actor utilizes a wide range of custom tools and malware, while maintaining a consistent attack chain approach, especially to organizations of interest to North Korean intelligence, such as those in the defense, engineering, and energy sectors. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. - Maintain good [cyber hygiene](https://www.microsoft.com/en-us/microsoft-365-life-hacks/privacy-and-safety/cyber-hygiene) and follow online safety best practices to help prevent keylogging. - Install antivirus software. Many antivirus software options now include anti-keylogger and anti-spyware protection. This software can help you identify and avoid keylogging malware. Installing and keeping antivirus software up to date helps prevents data theft. - Regularly update security settings, and if a device is no longer receiving updates, strongly consider replacing it with a new device. - Turn on [cloud-delivered protection](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/configure-block-at-first-sight-microsoft-defender-antivirus?ocid=magicti_ta_learndoc) in Microsoft Defender Antivirus, or the equivalent for your antivirus product, to cover rapidly evolving attacker tools and techniques.

2024-12-06 16:17:50 | Mauri Ransomware Threat Actors Exploiting Apache ActiveMQ Vulnerability (CVE-2023-46604) (lien direct) | ## Snapshot Researchers at AhnLab Security intelligence Response Center (ASEC) have identified that the [CVE-2023-46604](https://security.microsoft.com/intel-profiles/CVE-2023-46604) vulnerability in Apache ActiveMQ servers is being exploited on Korean systems. This vulnerability allows remote code execution by manipulating serialized class types in the OpenWire protocol. ## Description The vulnerability began to be actively exploited soon after its disclosure, with incidents linked to the Andariel group and [HelloKitty](https://www.rapid7.com/blog/post/2023/11/01/etr-suspected-exploitation-of-apache-activemq-cve-2023-46604/) ransomware. The targeting of unpatched systems has been continuous, with attackers deploying tools such as Ladon, Netcat, AnyDesk, and z0Miner to compromise environments. Recently, ASEC has observed evidence that Mauri ransomware threat actors are exploiting CVE-2023-46604, using Quasar RAT as part of the attack chain to exfiltrate information and gain control over systems through remote desktop. While no Mauri ransomware attacks have been confirmed, ASEC notes that Mauri ransomware has been uploaded to the download server. ## Microsoft Analysis and Additional OSINT Context Microsoft Threat Intelligence has identified threat activity exploiting CVE-2023-46604 to facilitate HelloKitty ransomware attacks. The threat actor exploited CVE-2023-46604 to deliver and launch malicious MSI binaries using misexec.exe. The actor then tampered with system services and launched the ransomware. Microsoft has also observed indicators of additional activity targeting ActiveMQ since late October 2023, though the exploitation method was not confirmed. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. Check the recommendations card for the deployment status of monitored mitigations. - Due to active attacks in the wild and the availability of exploitation details, organizations should upgrade affected servers immediately. According to Apache, upgrade ActiveMQ servers to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3 to address this issue. - Review logs and alerts for any indications of exploitation or post-compromise activity on affected servers, such as malicious files dropped and executed via the msiexec.exe command. Upgrading ActiveMQ will not remediate any attacker artifacts. - If evidence of exploitation is discovered, reset the credentials for accounts that have been used on the server, or have logged onto the server. Any service accounts related to ActiveMQ should also have their credentials rotated. - Harden servers by following Apache\'s [ActiveMQ security recommendations](https://activemq.apache.org/security). Enabling authentication for brokers can prevent an attacker from moving laterally to another broker without proper authentication. - Refer to our threat overview on [human-operated ransomwar](https://security.microsoft.com/threatanalytics3/05658b6c-dc62-496d-ad3c-c6a795a33c27/analystreport?ocid=magicti_ta_ta2)e for recommendations on security hardening and monitoring to defend against ransomware. - Turn on [cloud-delivered protection](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/configure-block-at-first-sight-microsoft-defender-antivirus?ocid=magicti_ta_learndoc) in Microsoft Defender Antivirus, or the equivalent for your antivirus product, to cover rapidly evolving attacker tools and techniques.

2024-11-22 21:45:45 | Helldown Ransomware: An Overview of this Emerging Threat (lien direct) | ## Snapshot Researchers at Sekoia have reported with medium confidence that the \'Helldown\' ransomware operation is exploiting vulnerabilities in Zyxel firewalls to infiltrate corporate networks. ## Description Helldown, which was first documented in August 2024, has been growing rapidly, listing numerous victims on its data extortion portal. The ransomware has a Linux variant that targets VMware files, with capabilities to list and kill VMs to encrypt images, though it appears to be under development. Helldown for Windows is believed to be based on the leaked LockBit 3 builder and shows operational similarities to Darkrace and Donex, but no definitive connection has been established. Helldown is not particularly selective in the data it steals, publishing large data packs on its website, with one instance reaching up to 431GB. The ransomware uses a random victim string as the extension for encrypted files and includes this string in the ransom note\'s filename. Sekoia\'s investigation suggests that Helldown may be using CVE-2024-42057, a command injection vulnerability in Zyxel firewalls\' IPSec VPN, to execute OS commands and establish a foothold in networks. The attackers reportedly use a malicious account to access domain controllers, move laterally, and disable endpoint defenses. Payloads connected to the Zyxel compromise were uploaded to VirusTotal from Russia, indicating the possibility of private n-day exploit usage. As of the latest reports, 31 victims have been listed on Helldown\'s extortion portal, primarily small and medium-sized firms in the United States and Europe. ## Recommendations Microsoft recommends the following mitigations to defend against this threat: - Keep software up to date. Apply new security patches as soon as possible. - Turn on [cloud-delivered protection](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/configure-block-at-first-sight-microsoft-defender-antivirus?ocid=magicti_ta_learndoc) in Microsoft Defender Antivirus, or the equivalent for your antivirus product, to cover rapidly evolving attacker tools and techniques. Cloud-based machine learning protections block a majority of new and unknown variants. - Enable [network protection](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/enable-network-protection?view=o365-worldwide?ocid=magicti_ta_learndoc) to help prevent access to malicious domains. - Run endpoint detection and response [(EDR) in block mode](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/edr-in-block-mode?ocid=magicti_ta_learndoc) so that Microsoft Defender for Endpoint can block malicious artifacts, even when your non-Microsoft antivirus does not detect the threat or when Microsoft Defender Antivirus is running in passive mode. EDR in block mode works behind the scenes to remediate malicious artifacts that are detected post-breach. - Configure [investigation and remediation](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/automated-investigations?ocid=magicti_ta_learndoc) in full automated mode to allow Microsoft Defender for Endpoint to take immediate action on alerts to resolve breaches, significantly reducing alert volume. - Read our [ransomware threat overview](https://security.microsoft.com/threatanalytics3/05658b6c-dc62-496d-ad3c-c6a795a33c27/analystreport) for advice on developing a holistic security posture to prevent ransomware, including credential hygiene and hardening Microsoft Defender customers can turn on [attack surface reduction rules](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/attack-surface-reduction?ocid=magicti_ta_learndoc) to help prevent common attack techniques used by Onyx Sleet: - [Block executable files from running unless they meet a prevalence, age, or trusted list criterion](https://learn.microsoft.com/defender-endpoint/attack-surface-reduction-rules-reference?ocid=magicti_ta_learndoc#block-executable-files-from-running-unless-they-meet-a-prevalence-a | Ransomware Malware Tool Vulnerability Threat | APT 45 | ★★ |

#### Géolocations ciblées - Taiwan - Vietnam - Philippines ## Instantané Des chercheurs de NTT ont identifié une vague d'attaques à partir de juillet 2024 qui exploitent la technique de l'injection du gestionnaire d'Appdomain qui a été inhabituellement observée dans la nature.Les attaques ont ciblé les agences gouvernementales à Taïwan, les militaires aux Philippines et les organisations énergétiques au Vietnam. ## Description Les attaques culminent dansDéploiement d'un [CobaltStrike] (https://security.microsoft.com/intel-profiles/fd8511c1d61e93d39411acf36a31130a6795efe186497098fe0c6f2ccfb920fc)Beacon, et il y a des indications de chevauchement avec les récents rapports AHNLAB, suggérant l'implication du groupe de menaces parrainé par l'État chinois, APT 41, bien que cette attribution ait une faible confiance.La technique d'injection du gestionnaire AppDomain exploite la classe AppDomainManager .NET Framework de. Les attaques observées par NTT commencent par la livraison d'une archive zip contenant un fichier MSC malveillant, qui exploite une vulnérabilité de script de sites croisées (XSS) dans la bibliothèque APDS.DLL de Windows pour exécuter du code arbitraire via Microsoft Management Console (MMC) en utilisantFichiers .MSC spécialement conçus.Ces fichiers .msc tirent parti de la technique GrimResource, ce qui permet l'exécution automatique des scripts lorsqu'un fichier est ouvert, éliminant le besoin d'interaction utilisateur.Cela conduit finalement au chargement d'une balise de Cobaltsstrike sur la machine, permettant un large éventail d'actions malveillantes.Selon NTT, la combinaison des techniques d'injection et de grimresource du gestionnaire d'Appdomain indique que les attaquants ont l'expertise technique pour utiliser des techniques nouvelles et moins connues dans des cas pratiques. ## Analyse Microsoft Les fichiers de console enregistrés (.MSC) de gestion sont utilisés pour stocker des configurations pour Microsoft Management Console (MMC), mais ils pourraient être abusés par les acteurs de la menace pour lancer un code malveillant.Microsoft Threat Intelligence a observé les acteurs de la menace [Emerald Sleet] (https://security.microsoft.com/intel-profiles/f1e214422dcaf4fb337dc703ee4ed596d8ae16f942f442b895752ad9f41dd58e) et [twill] (htypho urity.microsoft.com/intel-profiles/01aef6bb1a4cd12178aca7fceb848002164b83bf375fa33699ed4c5523b4fd3c) Utilisation de cette technique comme vecteur d'accès initial pour déployer des fichiers malveillants sur des appareils cibler.D'autres acteurs de menace ont déployé des logiciels malveillants tels que la grève de Cobalt en utilisant une technique que les chercheurs appelle GrimResource, qui fait référence à un fichier .MSC spécialement conçu qui utilise un défaut de script de site croisé (XSS) trouvé dans APDS.dll pour exécuter du code à l'aide de MMC. Microsoft Defender Antivirus détecte GrimResource et MALWORED déployé par ces fichiers .MSC malveillants.Lors de l'ouverture d'un fichier .msc téléchargé depuis Internet ou joint à un e-mail, un utilisateur doit accepter une invite d'avertissement de sécurité que le fichier .msc est lancé.Les organisations peuvent se défendre davantage contre cette technique en tirant parti des règles de réduction de la surface d'attaque pour limiter les types d'exécutables autorisés à s'exécuter dans votre environnement.

#### Géolocations ciblées - États-Unis - Australie - Japon - Corée - Nouvelle-Zélande - Allemagne - Royaume-Uni ## Instantané La Cybersecurity and Infrsatructure Security Agency (CISA) a publié un avis rédigé par un certain nombre d'organisations de cybersécurité d'État sur APT40, suivis par Microsoft comme [Gingham Typhoon] (https://security.microsoft.com C04BA1F56F4F603268AAB6). ## Description APT40, également connu sous le nom de Kryptonite Panda, Leviathan et Bronze Mohawk, mène des cyber opérations pour la République de Chine du peuple (PRC) du ministère de la Sécurité des États (MSS).Le groupe a une histoire de ciblage des organisations dans divers pays, dont les États-Unis et l'Australie. APT40 mène régulièrement la reconnaissance contre les réseaux d'intérêt, notamment ceux en Allemagne, en Nouvelle-Zélande, en Corée du Sud, au Japon, en Australie, au Royaume-Uni et aux États-Unis.Cela leur permet d'identifier les appareils vulnérables, de fin de vie ou non maintenus sur les réseaux et de déployer rapidement des exploits.APT40 est apte à exploiter les vulnérabilités dès 2017. De plus, l'APT40 est en mesure de profiter rapidement des vulnérabilités nouvellement publiques dans des logiciels communs tels que Log4J ([CVE-2021-44228] (https://security.microsoft.com/Intel-Explorer / Cves / CVE-2021-44228 /)), Atlassian Confluence ([CVE-2021-26084] (https://security.microsoft.com/intel-profiles/cve-2021-26084), et MicrosoftExchange ([CVE-2021-31207] (https: //sip.security.microsoft.com/intel-profiles/cve-2021-31207?tid=72f988bf-86f1-41af-91ab-2d7cd011db47), [cve-2021-34523] (https://security.microsoft.com/intel-expleror/cves://security.microsoft.com/intel-expleror/cves://security.microsoft.com/intel-expleror/cves://security.microsoft.com/intel-expleror/cves:/ CVE-2021-34523 /), [CVE-2021-34473] (https: // security.microsoft.com/intel-profiles/cve-2021-34473)). La CISA et les autres agences de déclaration évaluent que l'APT40 continuera d'exploiter les vulnérabilités nouvellement découvertes dans les heures ou les jours suivant la libération publique. APT40 exploite généralement une infrastructure vulnérable et orientée vers le public plutôt que d'employer des méthodes qui nécessitent une interaction victime, telles que les campagnes de phishing, en outre, le groupe utilise généralement des coquilles Web afin d'établir de la persistance. ## Analyse Microsoft L'acteur Microsoft suit comme [Typhoon Gingham] (https://security.microsoft.com/intel-profiles/a2fc1302354083f4e693158effdbc17987818a2433c04ba1f56f4f603268aab6) est un groupe de chinois à la base de Chine.Le Typhoon Gingham est connu pour cibler principalement les industries maritimes et de la santé, mais a également été observée ciblant un certain nombre de secteurs verticaux de l'industrie, notamment le monde universitaire, le gouvernement, l'aérospatiale / l'aviation, la base industrielle de la défense, la fabrication et le transport.La plupart des organisations ciblées par Typhoon enrichies se trouvent dans la région de la mer de Chine méridionale, mais le groupe cible également les organisations aux États-Unis, en Europe, au Moyen-Orient et en Asie du Sud-Est.Gingham Typoon se concentre généralement sur l'espionnage et le vol de données.Le groupe utilise des logiciels malveillants personnalisés (Moktik, Nuveridap et Fusionblaze), Derusbi et des outils disponibles dans le commerce tels que Cobalt Strike. ## Détections / requêtes de chasse Microsoft Defender Antivirus détecte les composants de la menace comme le malware suivant: [Backdoor: JS / MOKTIK] (https://www.microsoft.com/en-us/wdsi/Thereats/Malware-encyClopedia-Description?name=bacKDOOR: JS / MOKTIK & AMP; NOFENID = -2147086029) [HackTool: Win32 / Nuveridap] (https://www.microsoft.com/en-us/wdsi/atherets/malWare-SencyClopedia-Description?

Following the discovery of malware residing within ESXi hypervisors in September 2022, Mandiant began investigating numerous intrusions conducted by UNC3886, a suspected China-nexus cyber espionage actor that has targeted prominent strategic organizations on a global scale. In January 2023, Mandiant provided detailed analysis of the exploitation of a now-patched vulnerability in FortiOS employed by a threat actor suspected to be UNC3886. In March 2023, we provided details surrounding a custom malware ecosystem utilized on affected Fortinet devices. Furthermore, the investigation uncovered the compromise of VMware technologies, which facilitated access to guest virtual machines. Investigations into more recent operations in 2023 following fixes from the vendors involved in the investigation have corroborated Mandiant\'s initial observations that the actor operates in a sophisticated, cautious, and evasive nature. Mandiant has observed that UNC3886 employed several layers of organized persistence for redundancy to maintain access to compromised environments over time. Persistence mechanisms encompassed network devices, hypervisors, and virtual machines, ensuring alternative channels remain available even if the primary layer is detected and eliminated. This blog post discusses UNC3886\'s intrusion path and subsequent actions that were performed in the environments after compromising the guest virtual machines to achieve access to the critical systems, including: The use of publicly available rootkits for long-term persistence Deployment of malware that leveraged trusted third-party services for command and control (C2 or C&C) Subverting access and collecting credentials with Secure Shell (SSH) backdoors Extracting credentials from TACACS+ authentication using custom malware Mandiant has published detection and hardening guidelines for ESXi hypervisors and attack techniques employed by UNC3886.

Written by: Kelli Vanderlee, Jamie Collier
Executive Summary The election cybersecurity landscape globally is characterized by a diversity of targets, tactics, and threats. Elections attract threat activity from a variety of threat actors including: state-sponsored actors, cyber criminals, hacktivists, insiders, and information operations as-a-service entities. Mandiant assesses with high confidence that state-sponsored actors pose the most serious cybersecurity risk to elections. Operations targeting election-related infrastructure can combine cyber intrusion activity, disruptive and destructive capabilities, and information operations, which include elements of public-facing advertisement and amplification of threat activity claims. Successful targeting does not automatically translate to high impact. Many threat actors have struggled to influence or achieve significant effects, despite their best efforts. When we look across the globe we find that the attack surface of an election involves a wide variety of entities beyond voting machines and voter registries. In fact, our observations of past cycles indicate that cyber operations target the major players involved in campaigning, political parties, news and social media more frequently than actual election infrastructure. Securing elections requires a comprehensive understanding of many types of threats and tactics, from distributed denial of service (DDoS) to data theft to deepfakes, that are likely to impact elections in 2024. It is vital to understand the variety of relevant threat vectors and how they relate, and to ensure mitigation strategies are in place to address the full scope of potential activity. Election organizations should consider steps to harden infrastructure against common attacks, and utilize account security tools such as Google\'s Advanced Protection Program to protect high-risk accounts. Introduction The 2024 global election cybersecurity landscape is characterized by a diversity of targets, tactics, and threats. An expansive ecosystem of systems, administrators, campaign infrastructure, and public communications venues must be secured against a diverse array of operators and methods. Any election cybersecurity strategy should begin with a survey of the threat landscape to build a more proactive and tailored security posture. The cybersecurity community must keep pace as more than two billion voters are expected to head to the polls in 2024. With elections in more than an estimated 50 countries, there is an opportunity to dynamically track how threats to democracy evolve. Understanding how threats are targeting one country will enable us to better anticipate and prepare for upcoming elections globally. At the same time, we must also appreciate the unique context of different countries. Election threats to South Africa, India, and the United States will inevitably differ in some regard. In either case, there is an opportunity for us to prepare with the advantage of intelligence. |

## Snapshot Over the last year, the speed, scale, and sophistication of attacks has increased alongside the rapid development and adoption of AI. Defenders are only beginning to recognize and apply the power of generative AI to shift the cybersecurity balance in their favor and keep ahead of adversaries. At the same time, it is also important for us to understand how AI can be potentially misused in the hands of threat actors. In collaboration with OpenAI, today we are publishing research on emerging threats in the age of AI, focusing on identified activity associated with known threat actors, including prompt-injections, attempted misuse of large language models (LLM), and fraud. Our analysis of the current use of LLM technology by threat actors revealed behaviors consistent with attackers using AI as another productivity tool on the offensive landscape. You can read OpenAI\'s blog on the research [here](https://openai.com/blog/disrupting-malicious-uses-of-ai-by-state-affiliated-threat-actors). Microsoft and OpenAI have not yet observed particularly novel or unique AI-enabled attack or abuse techniques resulting from threat actors\' usage of AI. However, Microsoft and our partners continue to study this landscape closely. The objective of Microsoft\'s partnership with OpenAI, including the release of this research, is to ensure the safe and responsible use of AI technologies like ChatGPT, upholding the highest standards of ethical application to protect the community from potential misuse. As part of this commitment, we have taken measures to disrupt assets and accounts associated with threat actors, improve the protection of OpenAI LLM technology and users from attack or abuse, and shape the guardrails and safety mechanisms around our models. In addition, we are also deeply committed to using generative AI to disrupt threat actors and leverage the power of new tools, including [Microsoft Copilot for Security](https://www.microsoft.com/security/business/ai-machine-learning/microsoft-security-copilot), to elevate defenders everywhere. ## Activity Overview ### **A principled approach to detecting and blocking threat actors** The progress of technology creates a demand for strong cybersecurity and safety measures. For example, the White House\'s Executive Order on AI requires rigorous safety testing and government supervision for AI systems that have major impacts on national and economic security or public health and safety. Our actions enhancing the safeguards of our AI models and partnering with our ecosystem on the safe creation, implementation, and use of these models align with the Executive Order\'s request for comprehensive AI safety and security standards. In line with Microsoft\'s leadership across AI and cybersecurity, today we are announcing principles shaping Microsoft\'s policy and actions mitigating the risks associated with the use of our AI tools and APIs by nation-state advanced persistent threats (APTs), advanced persistent manipulators (APMs), and cybercriminal syndicates we track. These principles include: - **Identification and action against malicious threat actors\' use:** Upon detection of the use of any Microsoft AI application programming interfaces (APIs), services, or systems by an identified malicious threat actor, including nation-state APT or APM, or the cybercrime syndicates we track, Microsoft will take appropriate action to disrupt their activities, such as disabling the accounts used, terminating services, or limiting access to resources. - **Notification to other AI service providers:** When we detect a threat actor\'s use of another service provider\'s AI, AI APIs, services, and/or systems, Microsoft will promptly notify the service provider and share relevant data. This enables the service provider to independently verify our findings and take action in accordance with their own policies. - **Collaboration with other stakeholders:** Microsoft will collaborate with other stakeholders to regularly exchange information a | Ransomware Malware Tool Vulnerability Threat Studies Medical Technical | APT 28 ChatGPT APT 4 | ★★ |

Like any forty-year-old technology, SMS is antiquated compared to its modern counterparts. That\'s especially concerning when it comes to security.
The World Has Changed, But SMS Hasn\'t Changed With It
According to a recent whitepaper from Dekra, a safety certifications and testing lab, the security shortcomings of SMS can notably lead to:
SMS Interception: Attackers can intercept SMS messages by exploiting vulnerabilities in mobile carrier networks. This can allow them to read the contents of SMS messages, including sensitive information such as two-factor authentication codes, passwords, and credit card numbers due to the lack of encryption offered by SMS.
SMS Spoofing: Attackers can spoof SMS messages to launch phishing attacks to make it appear as if they are from a legitimate sender. This can be used to trick users into clicking on malicious links or revealing sensitive information. And because carrier networks have independently developed their approaches to deploying SMS texts over the years, the inability for carriers to exchange reputation signals to help identify fraudulent messages has made it tough to detect spoofed senders distributing potentially malicious messages.
These findings add to the well-established facts about SMS\' weaknesses, lack of encryption chief among them.
Dekra also compared SMS against a modern secure messaging protocol and found it lacked any built-in security functionality. According to Dekra, SMS users can\'t answer \'yes\' to any of the following basic security questions:
Confidentiality: Can I trust that no one else can read my SMSs?
Integrity: Can I trust that the content of the SMS that I receive is not modified?
Authentication: Can I trust the identity of the sender of the SMS that I receive?
But this isn\'t just theoretical: cybercriminals have also caught on to the lack of security protections SMS provides and have repeatedly exploited its weakness. Both novice hackers and advanced threat actor groups (such as UNC3944 / Scattered Spider and APT41 investigated by Mandiant, part of Google Cloud) leverage the security deficiencies in SMS to launch different |

[The Mind\'s Bias] Pretexting Now Tops Phishing in Social Engineering Attacks
The New Verizon DBIR is a treasure trove of data. As we will cover a bit below, Verizon reported that 74% of data breaches Involve the "Human Element," so people are one of the most common factors contributing to successful data breaches. Let\'s drill down a bit more in the social engineering section.
They explained: "Now, who has received an email or a direct message on social media from a friend or family member who desperately needs money? Probably fewer of you. This is social engineering (pretexting specifically) and it takes more skill.
"The most convincing social engineers can get into your head and convince you that someone you love is in danger. They use information they have learned about you and your loved ones to trick you into believing the message is truly from someone you know, and they use this invented scenario to play on your emotions and create a sense of urgency. The DBIR Figure 35 shows that Pretexting is now more prevalent than Phishing in Social Engineering incidents. However, when we look at confirmed breaches, Phishing is still on top."
A social attack known as BEC, or business email compromise, can be quite intricate. In this type of attack, the perpetrator uses existing email communications and information to deceive the recipient into carrying out a seemingly ordinary task, like changing a vendor\'s bank account details. But what makes this attack dangerous is that the new bank account provided belongs to the attacker. As a result, any payments the recipient makes to that account will simply disappear.
BEC Attacks Have Nearly Doubled
It can be difficult to spot these attacks as the attackers do a lot of preparation beforehand. They may create a domain doppelganger that looks almost identical to the real one and modify the signature block to show their own number instead of the legitimate vendor.
Attackers can make many subtle changes to trick their targets, especially if they are receiving many similar legitimate requests. This could be one reason why BEC attacks have nearly doubled across the DBIR entire incident dataset, as shown in Figure 36, and now make up over 50% of incidents in this category.
Financially Motivated External Attackers Double Down on Social Engineering
Timely detection and response is crucial when dealing with social engineering attacks, as well as most other attacks. Figure 38 shows a steady increase in the median cost of BECs since 2018, now averaging around $50,000, emphasizing the significance of quick detection.
However, unlike the times we live in, this section isn\'t all doom and |

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.

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.

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.

2022-03-10 23:39:03 | APT41 Compromised Six U.S. State Government Networks (lien direct) | FortiGuard Labs is aware of a report that threat actor APT41 compromised at least six networks belonging to U.S. state governments between May 2021 and February 2022. To gain a foothold into the victim's network, the threat actor used a number of different attack vectors: exploiting vulnerable Internet facing web applications and directory traversal vulnerabilities, performing SQL injection, and conducting de-serialization attacks. The intent of APT41 appears to be reconnaissance, though how the stolen information is to be used has not yet been determined.Why is this Significant? This is significant because at least six U.S. state government systems were broken into and data exfiltration was performed by APT41 as recent as February 2022 In addition, a zero-day vulnerability in the USAHerds application (CVE-2021-44207) as well as Log4j (CVE-2021-44228), among others, were exploited in the attacksWhat's the Detail of the Attack?APT41 performed several different ways to break into the targeted networks.In one case, the group exploited a SQL injection vulnerability in a Internet-facing web application. In another case, a then previously unknown vulnerability (CVE-2021-44207) in USAHerds, which is a web application used by agriculture officials to manage animal disease control and prevention, livestock identification and movement. Also, APT41 reportedly started to exploit the infamous Log4j vulnerability (CVE-2021-44228) within hours of Proof-of-Concept (PoC) code becoming available. Patches for both vulnerabilities are available. Once successful in breaking into the victim's network, the threat actor performed reconnaissance and credential harvesting activities. What is APT41?APT41 is a threat actor who has been active since at least 2012. Also known as TA415, Double Dragon, Barium, GREF and WickedPanda, the group reportedly performs Chinese state-sponsored espionage activities. APT41 targets organizations in multiple countries across a wide range of industries, such as telecommunications, industrial and engineering and think tanks. In 2020, five alleged members of the group were charged by the U.S. Justice Department for hacking more than 100 companies in the United States.What are the Tools Used by APT41?APT41 is known to use the following tools:ASPXSpy - web shell backdoorBITSAdmin - PowerShell cmdlets for creating and managing file transfers.BLACKCOFFEE - backdoor that disguise its communications as benign traffic to legitimate websites certutil - command-line utility tool used for manipulating certification authority (CA) data and components.China Chopper - web shell backdoor that allows attacker to have remote access to an enterprise networkCobalt Strike - a commercial penetration testing tool, which allows users to perform a wide range of activitiesDerusbi - DLL backdoorEmpire - PowerShell post-exploitation agent, which provides a wide range of attack activities to usersgh0st RAT - Remote Access Trojan (RAT)MESSAGETAP - data mining malware Mimikatz - open-source credential dumpernjRAT - Remote Access Trojan (RAT)PlugX - Remote Access Trojan (RAT)PowerSploit - open-source, offensive security framework which allows users to perform a wide range of activitiesROCKBOOT - BootkitShadowPad - backdoorWinnti for Linux - Remote Access Trojan (RAT) for LinuxZxShell - Remote Access Trojan (RAT)Badpotato - open-source tool that allows elevate user rights towards System rightsDustPan - shellcode loader. aka StealthVectorDEADEYE - downloaderLOWKEY - backdoorKeyplug - backdoorWhat are Other Vulnerabilities Known to be Exploited by APT41?APT41 exploited the following, but not restricted to, these vulnerabilities in the past:CVE-2020-10189 (ManageEngine Desktop Central remote code execution vulnerability)CVE-2019-19781 (Vulnerability in Citrix Application Delivery Controller, Citrix Gateway, and Citrix SD-WAN WANOP appliance)CVE-2019-3396 (Atlassian Confluence Widget Connector Macro Velocity Template Injection)CVE-2017-11882 (Microsoft Office Memory Corruption Vulnerability)CVE-2017-0199 (Microsoft Office/WordPad Remote Code Execut | Malware Tool Vulnerability Threat Guideline | APT 41 APT 15 APT 15 | |

What’s With The Shared VBA Code Between Transparent Tribe And Other Threat Actors?
(published: February 9, 2022)
A recent discovery has been made that links malicious VBA macro code between multiple groups, namely: Transparent Tribe, Donot Team, SideCopy, Operation Hangover, and SideWinder. These groups operate (or operated) out of South Asia and use a variety of techniques with phishing emails and maldocs to target government and military entities within India and Pakistan. The code is similar enough that it suggests cooperation between APT groups, despite having completely different goals/targets.
Analyst Comment: This research shows that APT groups are sharing TTPs to assist each other, regardless of motive or target. Files that request content be enabled to properly view the document are often signs of a phishing attack. If such a file is sent to you via a known and trusted sender, that individual should be contacted to verify the authenticity of the attachment prior to opening. Thus, any such file attachment sent by unknown senders should be viewed with the utmost scrutiny, and the attachments should be avoided and properly reported to appropriate personnel.

Fake Windows 11 Upgrade Installers Infect You With RedLine Malware
(published: February 9, 2022)
Due to the recent announcement of Windows 11 upgrade availability, an unknown threat actor has registered a domain to trick users into downloading an installer that contains RedLine malware. The site, "windows-upgraded[.]com", is a direct copy of a legitimate Microsoft upgrade portal. Clicking the 'Upgrade Now' button downloads a 734MB ZIP file which contains an excess of dead code; more than likely this is to increase the filesize for bypassing any antivirus scan. RedLine is a well-known infostealer, capable of taking screenshots, using C2 communications, keylogging and more.
Analyst Comment: Any official Windows update or installation files will be downloaded through the operating system directly. If offline updates are necessary, only go through Microsoft sites and subdomains. Never update Windows from a third-party site due to this type of attack.

FBI Warns Of Malicious QR Codes Used To Steal Your Money
(published: January 23, 2022)
The Federal Bureau of Investigation (FBI) recently released a notice that malicious QR codes have been found in the wild. These codes, when scanned, will redirect the victim to a site where they are prompted to enter personal and payment details. The site will then harvest these credentials for cybercriminals to commit fraud and empty bank accounts. This threat vector has been seen in Germany as of December 2021.
Analyst Comment: Always be sure to check that emails have been sent from a legitimate source, and that any financial details or method of payment is done through the website. While QR codes are useful and being used by businesses more often, it is easy for cybercriminals to perform this kind of scam. If scanning a physical QR code, ensure the code has not been replaced with a sticker placed on top of the original code. Check the final URL to make sure it is the intended site and looks authentic.

MoonBounce: The Dark Side Of UEFI Firmware
(published: January 20, 2022)
Kaspersky has reported that in September 2021, a bootloader malware infection had been discovered that embeds itself into UEFI firmware. The malware patches existing UEFI drivers and resides in the SPI flash memory located on the motherboard. This means that it will persist even if the hard drive is replaced. Code snippets and IP addresses link the activity to APT41, a group that is operated by a group of Chinese-speaking individuals. MoonBounce is highly sophisticated and very difficult to detect.
Analyst Comment: Systems should be configured to take advantage of Trusted Platform Module (TPM) hardware security chips to secure their systems' boot image and firmware, where available. Secure boot is also a viable option to mitigate against attacks that would patch, reconfigure, or flash existing UEFI firmware to implant malicious code.

Earth Lusca Employs Sophisticated Infrastructure, Varied Tools and Techniques
(published: January 17, 2022)
The Earth Lusca threat group is part of the Winnti cluster. It is one of different Chinese groups that share aspects of their tactics, techniques, and procedures (TTPs) including the use of Winnti malware. Earth Lusca were active throughout 2021 committing both cyberespionage operations against government-connected organizations and financially-motivated intrusions targeting gambling and cryptocurrency-related sectors. For intrusion, the group tries different ways in including: spearphishing, watering hole attacks, and exploiting publicly facing servers. Cobalt Strike is one of the group’s preferred post-exploitation tools. It is followed by the use of the BioPass RAT, the Doraemon backdoor, the FunnySwitch backdoor, ShadowPad, and Winnti. The group employs two separate infrastructure clusters, first one is rented Vultr VPS servers used for command-and-control (C2), second one is compromised web servers used to scan for vulnerabilities, tunnel traffic, and Cobalt Strike C2.
Analyst Comment: Earth Lusca often relies on tried-and-true techniques that can be stopped by security best practices, such as avoiding clicking on suspicious email/website links and or reacting on random banners urging to update important public-facing applications.

Phorpiex botnet is back with a new Twizt: Hijacking Hundreds of crypto transactions
(published: December 16, 2021)
Check Point Research has uncovered a new variant of the Phorpiex botnet named Twizt. Historically, Phorpiex utilized sextortion, ransomware delivery, and cryptocurrency clipping. Twizt however, appears to be primarily focused on stealing cryptocurrency and have stolen half a million dollars since November 2020 in the form of Bitcoin, Ether and ERC20 tokens.The botnet features departure from it’s traditional command and control (C2) infrastructure, opting for peer-to-peer (P2P) communications between infected hosts, eliminating the need for C2 communication as each host can fulfill that role.
Analyst Comment: Bots within a P2P network need to communicate regularly with other bots to receive and share commands. If the infected bots are on a private network, private IP addresses will be used. Therefore, careful monitoring of network traffic will reveal suspicious activity, and a spike in network resource usage as opposed to the detection of C2 IP addresses.

S.O.V.A. – A New Android Banking Trojan with Fowl Intentions
(published: September 10, 2021)
ThreatFabric researchers have discovered a new Android banking trojan called S.O.V.A. The malware is still in the development and testing phase and the threat actor is publicly-advertising S.O.V.A. for trial runs targeting banks to improve its functionality. The trojan’s primary objective is to steal personally identifiable information (PII). This is conducted through overlay attacks, keylogging, man-in-the-middle attacks, and session cookies theft, among others. The malware author is also working on other features such as distributed denial-of-service (DDoS) and ransomware on S.O.V.A.’s project roadmap.
Analyst Comment: Always keep your mobile phone fully patched with the latest security updates. Only use official locations such as the Google Play Store / Apple App Store to obtain your software, and avoid downloading applications, even if they appear legitimate, from third-party stores. Furthermore, always review the permissions an app will request upon installation.

Actively Exploited Bug Bypasses Authentication On Millions Of Routers
(published: August 7, 2021)
The ongoing attacks were discovered by Juniper Threat Labs researchers exploiting recently discovered vulnerability CVE-2021-20090. This is a critical path traversal vulnerability in the web interfaces of routers with Arcadyan firmware that could allow unauthenticated remote attackers to bypass authentication. The total number of devices exposed to attacks likely reaches millions of routers. Researchers identified attacks originating from China and are deploying a variant of Mirai botnet on vulnerable routers.
Analyst Comment: Attackers have continuous and automated routines to look out for publicly accessible vulnerable routers and exploit them as soon as the exploit is made public. To reduce the attack surface, routers management console should only be accessible from specific public IP addresses. Also default password and other security policies should be changed to make it more secure.

UK and Allies Accuse China for a Pervasive Pattern of Hacking, Breaching Microsoft Exchange Servers
(published: July 19, 2021)
On July 19th, 2021, the US, the UK, and other global allies jointly accused China in a pattern of aggressive malicious cyber activity. First, they confirmed that Chinese state-backed actors (previously identified under the group name Hafnium) were responsible for gaining access to computer networks around the world via Microsoft Exchange servers. The attacks took place in early 2021, affecting over a quarter of a million servers worldwide. Additionally, APT31 (Judgement Panda) and APT40 (Kryptonite Panda) were attributed to Chinese Ministry of State Security (MSS), The US Department of Justice (DoJ) has indicted four APT40 members, and the Cybersecurity and Infrastructure Security Agency (CISA) shared indicators of compromise of the historic APT40 activity.
Analyst Comment: Network defense-in-depth and adherence to information security best practices can assist organizations in reducing the risk. Pay special attention to the patch and vulnerability management, protecting credentials, and continuing network hygiene and monitoring. When possible, enforce the principle of least privilege, use segmentation and strict access control measures for critical data. Organisations can use Anomali Match to perform real time forensic analysis for tracking such attacks.

Google: This Spectre proof-of-concept shows how dangerous these attacks can be
(published: March 15, 2021)
Google has released a proof of concept (PoC) code to demonstrate the practicality of Spectre side-channel attacks against a browser's JavaScript engine to leak information from its memory. Spectre targeted the process in modern CPUs called speculative execution to leak secrets such as passwords from one site to another. While the PoC demonstrates the JavaScript Spectre attack against Chrome 88's V8 JavaScript engine on an Intel Core i7-6500U CPU on Linux, Google notes it can easily be tweaked for other CPUs, browser versions and operating systems.
Analyst Comment: As the density of microchip manufacturing continues to increase, side-channel attacks are likely to be found across many architectures and are difficult (and in some cases impossible) to remediate in software. The PoC of the practicality of performing such an attack using javascript emphasises that developers of both software and hardware be aware of these types of attacks and the means by which they can be used to invalidate existing security controls.

Threat Assessment: DearCry Ransomware
(published: March 12, 2021)
A new ransomware strain is being used by actors to attack unpatched Microsoft Exchange servers. Microsoft released patches for four vulnerabilities that are being exploited in the wild. The initial round of attacks included installation of web shells onto affected servers that could be used to infect additional computers. While the initial attack appears to have been done by sophisticated actors, the ease and publicity around these vulnerabilities has led to a diverse group of actors all attempting to compromise these servers.
Analyst Comment: Patch and asset management are a critical and often under-resourced aspect of defense in depth. As this particular set of vulnerabilities and attacks are against locally hosted Exchange servers, organization may want to assess whether a hosted solution may make sense from a risk standpoint

US 2020 Presidential Apps Riddled with Tracking and Security Flaws
(published: September 17, 2020)
The Vote Joe 2020 application has been found to be potentially leaking personal data about voters. The app is used by the Joe Biden campaign to engage with voters and get supporters to send out promotional text messages. Using TargetSmart, an intelligence service, the app receives their predictions via API endpoint which has been found to be returning additional data. Voter preference and voter prediction could be seen, while voter preference is publically accessible, the information for TargetSmart was not meant to be publicly available. The app also let users from outside of the United States download, allowing for non-US citizens to have access to the data, as there was no email verification. Vote Joe isn’t the only campaign app with security issues, as the Donald Trump application exposed hardcoded secret keys in the APK.
Recommendation: The exposure of Personally Identifiable Information (PII) requires affected individuals to take precautionary measures to protect their identity and their finances. Identity theft services can assist in preventing illicit purchases, or applying for financial services from taking place by actors using stolen data.

German Hospital Attacked, Patient Taken to Another City Dies
(published: September 17, 2020)
A failure in IT systems at Duesseldorf University Hospital in Germany has led to the death of a woman. In an apparent ransomware attack, the hospital’s systems crashed with staff unable to access data. While there was no apparent ransom note, 30 servers at the hospital had been encrypted last week, with a ransom note left on one server addressed to Heinrich Heine University. Duesseldorf police contacted the perpetrators to inform them they had attacked the hospital instead of the university, with the perpetrators providing decryption keys, however patients had to be rerouted to other hospitals and therefore a long time before being treated by doctors.
Recommendation: Educate your employees on the risks of opening attachments from unknown senders. Anti-spam and antivirus applications provided by trusted vendors should also be employed. Emails that are received from unknown senders should be carefully avoided, and attachments from such senders should not be opened. Furthermore, it is important to have a comprehensive and tested backup solution in place, in addition to a business continuity plan for the unfortunate case of ransomware infection.
