2024-06-03 14:03:42 | Faits saillants hebdomadaires, 3 juin 2024 Weekly OSINT Highlights, 3 June 2024 (lien direct) |
## Snapshot Last week\'s OSINT reporting reveals a landscape of diverse cyber threats characterized by sophisticated attack tactics and adaptable threat actors. One key trend is the exploitation of popular platforms and applications, such as the Google Play store, fake Arc browser ads, and TXZ file attachments in malspam campaigns. Phishing and social engineering attacks also featured prominently this week, exemplified by piano-themed scams and phishing emails masquerading as PDF viewer login pages. Threat actors range from organized APT groups like LilacSquid and Andariel Group (tracked by Microsoft as Onyx Sleet) to financially motivated cybercriminals conducting advance fee fraud scams and phishing attacks. The targets are equally varied, spanning financial institutions, government departments, educational institutions, and sectors like IT, energy, and pharmaceuticals. These articles underscore the growing use of advanced techniques, such as leveraging AI for influence operations, exploiting software features like BitLocker for encryption attacks, and introducing backdoors through supply chain compromises. This highlights the evolving threat landscape where attackers continuously refine their methods to exploit both technological advancements and human vulnerabilities. ## Description 1. [Over 90 Malicious Apps Identified on Google Play Store](https://security.microsoft.com/intel-explorer/articles/e21eabb7): Zscaler ThreatLabz discovered over 90 malicious apps on Google Play, primarily distributing Anatsa malware targeting banking credentials through overlay and accessibility techniques. The malware, affecting financial institutions in various countries, evades detection and communicates with C2 servers to steal user credentials. 2. [Arc Browser Targeted by Malvertising Campaign](https://security.microsoft.com/intel-explorer/articles/9dd6578a): Cybercriminals launched a malvertising campaign impersonating the Arc browser to distribute malware, tricking users with official-looking ads. The malware is stealthily installed alongside the legitimate browser, making detection difficult as it contacts MEGA cloud services for malicious activities. 3. [VBScript Exploits BitLocker for Unauthorized Encryption](https://security.microsoft.com/intel-explorer/articles/7589c689): Kaspersky researchers identified an advanced VBScript exploiting BitLocker to encrypt unauthorized files, targeting systems in Mexico, Indonesia, and Jordan. The script gathers OS information, manipulates disk partitions, and uses a unique encryption key, effectively locking victims out of their data without recovery options. 4. [Piano-Themed AFF Scams Target North American Universities](https://security.microsoft.com/intel-explorer/articles/0bd219dd): Proofpoint uncovered email campaigns using piano-themed messages to lure victims into advance fee fraud scams, primarily targeting North American educational institutions. Threat actors demand shipping payments for fake pianos and collect personal information, with the scams generating significant financial transactions. 5. [TXZ Extension Used in Regionally Targeted Malspam Campaigns](https://security.microsoft.com/intel-explorer/articles/e9845916): SANS Internet Storm Center researchers found threat actors using TXZ extension files as malspam attachments in campaigns targeting regions like Spain, Slovakia, Croatia, and Czechia. The renamed RAR archives distribute malware like GuLoader and FormBook, leveraging Windows 11\'s native support for these file types. 6. [Phishing Emails Masquerade as PDF Viewer Login Pages](https://sip.security.microsoft.com/intel-explorer/articles/01780949): Forcepoint warns of phishing emails targeting Asia-Pacific government departments, using fake PDF viewer login pages to harvest credentials. The emails contain obfuscated JavaScript, redirecting victims to fake invoice pages and stealing their login information. 7.

Written by: Bavi Sadayappan, Zach Riddle, Jordan Nuce, Joshua Shilko, Jeremy Kennelly
A version of this blog post was published to the Mandiant Advantage portal on April 18, 2024. Executive Summary In 2023, Mandiant observed an increase in ransomware activity as compared to 2022, based on a significant rise in posts on data leak sites and a moderate increase in Mandiant-led ransomware investigations. Mandiant observed an increase in the proportion of new ransomware variants compared to new families, with around one third of new families observed in 2023 being variants of previously identified ransomware families. Actors engaged in the post-compromise deployment of ransomware continue to predominately rely on commercially available and legitimate tools to facilitate their intrusion operations. Notably, we continue to observe a decline in the use of Cobalt Strike BEACON, and a corresponding increase in the use of legitimate remote access tools. In almost one third of incidents, ransomware was deployed within 48 hours of initial attacker access. Seventy-six percent (76%) of ransomware deployments took place outside of work hours, with the majority occurring in the early morning. Mandiant\'s recommendations to assist in addressing the threat posed by ransomware are captured in our Ransomware Protection and Containment Strategies: Practical Guidance for Hardening and Protecting Infrastructure, Identities and Endpoints white paper. Introduction Threat actors have remained driven to conduct ransomware operations due to their profitability, particularly in comparison to other types of cyber crime. Mandiant observed an increase in ransomware activity in 2023 compared to 2022, including a 75% increase in posts on data leak sites (DLS), and an over 20% increase in Mandiant-led investigations involving ransomware from 2022 to 2023 (Figure 1). These observations are consistent with other reporting, which shows a record-breaking more than $1 billion USD paid to ransomware attackers in 2023. This illustrates that the slight dip in extortion activity observed in 2022 was an anomaly, potentially due to factors such as the invasion of Ukraine and the leaked CONTI chats. The current resurgence in extortion activity is likely driven by various factors, including the resettling of the cyber criminal ecosystem following a tumultuous year in 2022, new entrants, and new partnerships and ransomware service offerings by actors previously associated with prolific groups that had been disrupted. This blog post provides an overview of the ransomware landscape and common tactics, techniques, and procedures (TTPs) directly observed by Mandiant in 2023 ransomware incidents. Our analysis of TTPs relies primarily on data from Mandiant incident response engagements and therefore represe |

2024-06-03 12:56:15 | Les efforts d'influence russe convergent les Jeux olympiques de Paris 2024 Russian Influence efforts converge on 2024 Paris Olympics Games (lien direct) |
## Snapshot In the summer of 2023, a curious set of videos crept into social media platforms. Telegram feeds that normally promoted pro-Kremlin narratives suddenly began promoting a film called “Olympics Has Fallen.” Users were encouraged to scan a QR code that directed them to a Telegram channel of the same name. Upon arriving at this channel, viewers encountered a feature-length film with a similar aesthetic and a play on the title of the American political action movie “Olympus Has Fallen,” released more than a decade earlier.(1) AI-generated audio impersonating the voice of film actor Tom Cruise narrated a strange, meandering script disparaging the International Olympic Committee\'s leadership. Nearly a year later and with less than 80 days until the opening of the 2024 Paris Olympic Games, the Microsoft Threat Analysis Center (MTAC) has observed a network of Russia-affiliated actors pursuing a range of malign influence campaigns against France, French President Emmanuel Marcon, the International Olympic Committee (IOC), and the Paris Games. These campaigns may forewarn coming online threats to this summer\'s international competition. ## Activity Overview ### Russia\'s long history of disparaging the Olympic Games Modern Russia, as well as its predecessor the Soviet Union, has a longstanding tradition of seeking to undermine the Olympic Games. If they cannot participate in or win the Games, then they seek to undercut, defame, and degrade the international competition in the minds of participants, spectators, and global audiences. The Soviet Union boycotted the 1984 Summer Games held in Los Angeles and sought to influence other countries to do the same. US State Department officials linked Soviet actors to a campaign that covertly distributed leaflets to Olympic committees in countries including Zimbabwe, Sri Lanka, and South Korea.(2) The leaflets claimed non-white competitors would be targeted by US extremists-a claim that follows a tried-and-true active measures strategy: using divisive social issues to sow discord among a target audience.(3) A recurring aspect of Russian malign influence is its ability to resurface themes at a later time in a different country. Remarkably, four decades later, we are witnessing similar claims of anticipated extremist violence emerging in the context of the Paris Games this summer. Separately, in 2016, Russian hackers penetrated the World Anti-Doping Agency and revealed private medical information about American athletes Serena Williams, Venus Williams, and Simone Biles.(4) Two years later, the “Olympic Destroyer” cyberattack against the 2018 Winter Olympics in Pyeongchang, South Korea, managed to take some of the Winter Games\' internal servers offline. The US Department of Justice charged two Russian GRU officers in connection to the hack in 2020.(5) The slow burn of Russian President Vladimir Putin and the Kremlin\'s displeasure with the IOC and the ability to participate in the Olympics-an event of longstanding pride to the Russian government-has intensified in recent years. In 2017, the IOC concluded extensive investigations into Russia\'s state-sponsored use of performance-enhancing drugs across several Olympic Games in 2017 which resulted in Russia being formally barred from participating in the 2018 Winter Games.(6) Last year, in 2023, the IOC confirmed that Russian citizens would be allowed to compete in Paris but only as neutral athletes prohibited from sporting the flag or colors of the Russian Federation.(7) Shortly after this decision, MTAC began detecting a range of foreign malign influence operations that continue today, and we suspect may intensify as the 2024 Paris Opening Ceremony approaches.(8) ### Old world tactics meet the age of AI Starting in June 2023, prolific Russian influence actors-which Microsoft tracks as Storm-1679 and Storm-1099-pivoted their operations to take aim at the 2024 Olympic Games and French President Emmanuel Macron. These ongoing Russian influence operations have two cent | Hack Tool Threat Legislation Medical | ★★★ | |

The content of this post is solely the responsibility of the author. LevelBlue does not adopt or endorse any of the views, positions, or information provided by the author in this article. The critical role of security testing within software development cannot be overstated. From protecting personal information to ensuring that critical infrastructure remains unbreachable, security testing serves as the sentry against a multitude of cyber threats. Vulnerabilities and design weaknesses within software are like hidden fault lines; they may remain unnoticed until they cause significant damage. These flaws can compromise sensitive data, allow unauthorized access, and disrupt service operations. The repercussions extend beyond the digital world. They can lead to tarnished reputations, legal penalties, and, in extreme cases, endangerment of lives. Understanding these potential impacts underscores the crucial role of security testing as a protective measure. Security testing functions like a health check-up for software, identifying vulnerabilities in much the same way a doctor\'s examination would. Being proactive rather than reactive is essential here. It is always better to prevent than to cure. Security testing transcends the mere act of box-ticking; it is a vital, multi-layered process that protects both the integrity of the software and the privacy of its users. And it is not only about finding faults but also about instilling a culture of security within the development lifecycle. Understanding Security Testing Once more, the primary role of security testing is to identify and help fix security flaws within a system before they can be exploited. Consider it a comprehensive evaluation process that simulates real-world attacks, designed to ensure that the software can withstand and counter a variety of cybersecurity threats. By conducting security testing, developers can provide assurance to investors and users that their software is not only functional but also secure against different attacks. There is a diverse arsenal of methodologies available for security testing: 1) Penetration Testing Penetration testing, also known as ethical hacking, entails conducting simulated cyber-attacks on computer systems, networks, or web applications to uncover vulnerabilities that could be exploited. Security experts use pentest platforms and act as attackers and try to breach the system\'s defenses using various techniques. This method helps uncover real-world weaknesses as well as the potential impact of an attack on the system\'s resources and data. 2) Code Review A code review is a systematic examination of the application source code to detect security flaws, bugs, and other errors that might have been overlooked during the initial development phases. It involves manually reading through the code or using automated tools to ensure compliance with coding standards and to check for security vulnerabilities. This process helps in maintaining a high level of security by ensuring that the code is clean, efficient, and robust against cyber threats. 3) Vulnerability Assessment Unlike penetration testing, which attempts to exploit vulnerabilities, vulnerability assessment focuses on listing potential vulnerabilities without simulating attacks.

Au cours des trois derniers mois, Openai a contrecarré cinq iOS secrètes qui ont exploité ses modèles pour générer divers types de contenu, des commentaires sur les réseaux sociaux aux articles longs, dans plusieurs langues.Ces opérations proviennent de pays tels que la Russie, la Chine, l'Iran et Israël, et ont ciblé divers problèmes géopolitiques tels que l'invasion de l'Ukraine par la Russie, le conflit à Gaza et la politique en Europe et aux États-Unis.Malgré ces efforts, les campagnes d'influence n'ont pas atteint un engagement important du public, car aucun n'a marqué plus d'un 2 sur l'échelle de Brookings \\ ', indiquant un impact minimal.Les opérations ont combiné le contenu généré par l'IA avec des médias traditionnels et visaient à simuler l'engagement plutôt que d'attirer des interactions authentiques.
OpenAI a identifié quatre tendances clés dans la façon dont les opérations d'influence secrètes ont récemment utilisé des modèles d'IA.Premièrement, la génération de contenu: ces acteurs de menace ont utilisé des services OpenAI pour produire du texte (et parfois des images) dans des volumes plus importants et avec moins d'erreurs linguistiques que les opérateurs humains pourraient réaliser seuls.Deuxièmement, le mélange ancien et nouveau: Bien que l'IA ait été habituée dans une certaine mesure dans toutes les opérations, elle n'a pas été utilisée exclusivement.Au lieu de cela, le contenu généré par l'IA était l'un des nombreux types de contenu affichés, aux côtés de formats traditionnels comme des textes ou des mèmes écrits manuellement provenant d'Internet.Troisièmement, truquer l'engagement: certains réseaux ont utilisé les services d'Openai \\ pour simuler l'engagement des médias sociaux, générant des réponses à leurs propres messages.Cependant, cela ne s'est pas traduit par un véritable engagement, ce qu'aucun de ces réseaux n'a réussi à réaliser de manière significative.Enfin, les gains de productivité: de nombreux acteurs de menace ont utilisé les services d'Openai \\ pour stimuler l'efficacité, par exemple en résumant les publications sur les réseaux sociaux ou le code de débogage.
Pour les praticiens de la cybersécurité, il est crucial de comprendre les tendances opérationnelles de ces iOS.Les stratégies défensives contre une telle utilisation abusive comprennent la mise en œuvre de systèmes de sécurité robustes dans les modèles d'IA, qui peuvent empêcher la génération de contenu malveillant et exploiter des outils améliorés par l'IA pour rationaliser les enquêtes.Le partage des indicateurs de menaces et des informations au sein de l'industrie s'avère également vitaux pour amplifier l'impact des perturbations.Les praticiens doivent rester vigilants de l'élément humain de ces opérations, car les attaquants sont sujets à des erreurs qui peuvent être exploitées pour la détection et l'atténuation.En adoptant ces stratégies, les professionnels de la cybersécurité peuvent mieux se défendre contre les opérations sophistiquées d'influence sur l'IA.

## Snapshot Cisco Talos has disclosed a new suspected data theft campaign, active since at least 2021, attributed to an advanced persistent threat actor (APT) called "LilacSquid". ## Description The campaign uses MeshAgent, an open-source remote management tool, and a customized version of QuasarRAT called "PurpleInk" to serve as the primary implants after successfully compromising vulnerable application servers exposed to the internet. The campaign leverages vulnerabilities in public-facing application servers and compromised remote desktop protocol (RDP) credentials to orchestrate the deployment of a variety of open-source tools, such as MeshAgent and SSF, alongside customized malware, such as "PurpleInk," and two malware loaders called "InkBox" and "InkLoader." The campaign is geared toward establishing long-term access to compromised victim organizations to enable LilacSquid to siphon data of interest to attacker-controlled servers. LilacSquid\'s victimology includes a diverse set of victims consisting of information technology organizations building software for the research and industrial sectors in the United States, organizations in the energy sector in Europe, and the pharmaceutical sector in Asia, indicating that the threat actor may be agnostic of industry verticals and trying to steal data from a variety of sources. ## Detections/Hunting Queries # Recommendations to protect against Information Stealers Microsoft recommends the following mitigations to reduce the impact of Information stealer threats. - Check your Office 365 email filtering settings to ensure you block spoofed emails, spam, and emails with malware.

2024-05-30 10:00:00 | Transition du stockage sur site au cloud AWS: un guide stratégique pour les entreprises Transitioning from On-Premise Storage to AWS Cloud: A Strategic Guide for Companies (lien direct) |
The content of this post is solely the responsibility of the author. LevelBlue does not adopt or endorse any of the views, positions, or information provided by the author in this article. In today’s digital world, businesses face the challenge of managing ever-expanding volumes of data efficiently and securely. Traditional on-premise storage solutions often come with limitations in scalability, flexibility, and cost-effectiveness. Recognizing these drawbacks, many companies are turning to cloud computing platforms like Amazon Web Services (AWS) to harness the power of cloud storage solutions. Transitioning from on-premise storage to AWS cloud can be a transformative journey for businesses, enabling them to streamline operations and enhance data accessibility. In this article, we will explore the steps involved in this transition and the benefits it offers to businesses. Understanding the Need for Transition Before exploring the transition process, it’s crucial for businesses to understand the reasons behind their decision to migrate from on-premise storage to the AWS cloud. Several factors often drive this decision: Scalability: On-premise storage solutions have limited capacities, making it challenging for businesses to scale their storage infrastructure rapidly in response to growing amounts of data. AWS cloud offers virtually unlimited storage capacity, allowing businesses to scale up or down as needed without the hassle of physical hardware upgrades. Flexibility: Traditional storage architectures lack the ability to adapt to changing business requirements quickly. AWS cloud provides a wide range of storage services, such as Amazon S3, Amazon EBS, and Amazon Glacier, each tailored to specific use cases. This flexibility enables businesses to choose storage solutions that best suit their needs and easily adjust them as requirements evolve. Cost Efficiency: Maintaining on-premise storage infrastructure requires significant upfront investments in hardware, maintenance, and personnel. AWS cloud operates on a pay-as-you-go model, allowing businesses to pay only for the resources they consume. This cost-efficient approach eliminates the need for extraneous expenditures and reduces overall storage costs. Enhanced Security and Compliance: AWS offers robust security features and compliance certifications, ensuring data stored in the cloud remains protected against threats and meets regulatory requirements. By leveraging AWS security services like AWS Identity and Access Management (IAM) and Amazon Macie, businesses can enhance data security and ensure compliance. Strategic Steps in Transitioning to AWS Cloud Transitioning from on-premise storage to AWS cloud requires careful planning and execution to minimize disruption to business operations. Here are strategic steps involved in the transition process: Assessment and Planning: Begin by conducting a comprehensive assessment of your existing on-premise storage infrastructure, including data volumes, types, and access patterns. Identify workloads suitable for migration to the cloud and prioritize them based on business criticality. Develop a detailed migration plan outlining timelines, resource requirements, and potential challenges. Data Migration Strategy: Choose the appropriate migration strategy based on your business requirements and data characteristics. AWS offers several migration options, including: Rehosting: Migrate existing virtual machines or applications to AWS using services like AWS Server Migration Service (SMS). Replatforming: Optimize applications for cloud-native architectures while retaining core functionalities. Refactoring: Redesign applications to leverage cloud-native services and take full advantage of AWS capabilities. | Tool Cloud | ★★ | |

#### Géolocations ciblées - Croatie - Espagne - Slovaquie - Tchéchie ## Instantané Des chercheurs du SANS Internet Storm Center ont découvert que les acteurs de la menace utilisent des fichiers avec TXZ Extension comme pièces jointes Malspam dans des campagnes ciblées régionalement. ## Description L'utilisation de l'extension TXZ est relativement inhabituelle et les chercheurs en sécurité ont révélé que les fichiers malveillants étaient en fait renommés des archives RAR.Microsoft a ajouté la prise en charge native à Windows 11 pour les fichiers TXZ et RAR à la fin de l'année dernière, ce qui peut avoir facilité les destinataires potentiels des messages malveillants pour ouvrir les pièces jointes à l'aide de l'explorateur de fichiers Windows standard, même si l'extension et le type de fichier ont été incompatibles. Les messages malveillants faisaient partie de deux campagnes, l'une contenant des textes dans les langues espagnols et slovaques et distribuant un fichier de 464 kb PE avec Guloder Maleware, et l'autre contenant des textes dans les langues croate et tchèque et distribuant un téléchargement de fichiers par lots de 4 kb pour le Formbook Micware et la distribution d'un fichier de fichiers de 4 kb pour le FormBook Micware Formbook et la distribution d'un téléchargement de fichiers par lots de 4 kb pour le FormBook Micware FormBook. ## Analyse supplémentaire Guloader est un téléchargeur de shellcode proéminent qui a été utilisé dans un grand nombre d'attaques pour fournir une large gamme de logiciels malveillants.Découvert en 2019, Guloader a commencé comme une famille de logiciels malveillants écrite dans Visual Basic 6 (VB6), selon la sécurité [chercheurs de CrowdStrike] (https://security.microsoft.com/intel-explorer/articles/49c83a74).In 2023, [Researchers at CheckPoint](https://security.microsoft.com/intel-explorer/articles/661847be) discovered that more recent versions of GuLoader integrated new anti-analysis techniques and a payload that is fully encrypted, including PEen-têtes.Cela permet aux acteurs de la menace de stocker des charges utiles à l'aide de services de cloud public bien connues, de contourner les protections antivirus et de conserver les charges utiles disponibles en téléchargement pendant une longue période. FormBook, un voleur d'informations (InfoSteller) malware découvert en 2016, possède diverses capacités telles que le suivi des touches, l'accès aux fichiers, la capture de captures d'écran et le vol de mots de passe des navigateurs Web.Ces dernières années, [Microsoft a suivi le risque croissant que les infostateurs présentent à la sécurité des entreprises] (https://security.microsoft.com/intel-profiles/2296d491ea381b532b24f2575f9418d4b6723c17b8a1f507d20c2140a75d6d6).Les infostateurs sont des logiciels malveillants de marchandises utilisés pour voler des informations à un appareil cible et l'envoyer à l'acteur de menace.La popularité de cette classe de logiciels malveillants a conduit à l'émergence d'un écosystème d'infosteller et à une nouvelle classe d'acteurs de menace qui a exploité ces capacités pour mener leurs attaques.Les infostelleurs sont polyvalents et peuvent être distribués sous diverses formes, notamment par le biais de campagnes par e-mail de phishing, de malvertising et de logiciels, de jeux et d'outils maltraités. ## Détections / requêtes de chasse ### Microsoft Defender Antivirus Microsoft Defender Antivirus détecte les composants de la menace comme le malware suivant: - [Trojandownloader: MSIL / Formbook] (Https: //www.microsoft.com/en-us/wdsi/therets/malware-encyclopedia-dercription? name = trojandownloher: MSIL / Formbook.kan!

Memory forensics is a critical aspect of digital forensics, allowing investigators to analyze the volatile memory of a system to uncover evidence of malicious activity, detect hidden malware, and reconstruct system events. In this blog, we\'ll explore the world of memory forensics using two powerful tools: Fmem and LiME. We\'ll delve into the basics of memory forensics, explore the features and capabilities of Fmem and LiME, and provide a step-by-step guide on how to use these tools to analyze a memory dump.
What is Memory Forensics?
Memory forensics involves the analysis of a system\'s volatile memory to extract valuable information about system state, running processes, and network connections. This type of analysis is crucial in incident response, malware analysis, and digital forensics investigations. By analysing memory, investigators can:
1. Detect Hidden Malware and Rootkits:
Memory forensics enables investigators to uncover hidden malware and rootkits that may be actively running in a system\'s memory. Unlike traditional antivirus software that primarily scans the file system, memory forensics tools can identify malicious code and processes that attempt to evade detection by residing solely in memory.
2. Identify Malicious Processes and Network Connections:
By analyzing the contents of a system\'s memory, forensic analysts can identify suspicious processes and network connections. This includes processes that may be performing malicious activities such as data exfiltration, privilege escalation, or network reconnaissance. Identifying these malicious entities is crucial for understanding the scope and impact of a security incident.
3. Reconstruct System Events and Timelines:
Memory forensics allows investigators to reconstruct the sequence of events that occurred on a system leading up to and during a security incident. By analyzing memory artifacts such as process creation timestamps, network connection logs, and registry modifications stored in memory, investigators can create a detailed timeline of activities, which aids in understanding the tactics and techniques employed by attackers.
4. Extract Sensitive Data:
Volatile data, such as passwords, encryption keys, and other sensitive information, may be present in a system\'s memory during normal operation. Memory forensics tools can extract this data from memory dumps, providing valuable evidence for digital investigations. This information can be crucial for understanding how attackers gained access to sensitive resources and for mitigating potential security risks.
Using fmem for Memory Capture:
fmem is a kernel module that creates a virtual device, /dev/fmem, which allows direct access to the physical memory of a system. This module is particularly useful for acquiring memory dumps of a compromised system, even if the system is protected by Secure Boot or has disabled the ability to read physical memory directly.
Follow these steps to capture memory using fmem: Download the fmem source code from the official repository or package manager. The same can be found here.
Once cloned into the repository, change directory to fmem using cd command. You can use ls command to list the contents of the directory.
Compile and install fmem on the target Linux system:

#### Géolocations ciblées

- Jordan
## Instantané
Des chercheurs de Kapersky ont identifié un incident dans lequel les attaquants se sont déployés et un script de base visuel avancé (VBScript) qui a profité du bitlocker pour le cryptage de fichiers non autorisé.
## Description
Bitlocker a été initialement conçu pour protéger les données contre le vol ou l'exposition lorsque les appareils sont perdus, volés ou mal éliminés.Cependant, les attaquants ont découvert comment exploiter cette fonctionnalité à des fins malveillantes.Les chercheurs de Kapersky ont détecté ce script et ses versions modifiées au Mexique, en Indonésie et en Jordanie.
Initialement, le script utilise Windows Management Instrumentation (WMI) pour collecter des informations sur le système d'exploitation (OS).Il vérifie le domaine et la version du système d'exploitation actuels, se terminant s'il rencontre certaines conditions, telles que les anciennes versions Windows comme XP ou Vista.
Le script effectue des opérations de redimensionnement du disque uniquement sur des disques fixes pour éviter les outils de détection sur les lecteurs de réseau.Pour Windows Server 2008 et 2012, il rétrécit les partitions non-Boot, crée de nouvelles partitions, les formats et réinstalle les fichiers de démarrage à l'aide de DiskPart et BCDBoot.Pour d'autres versions Windows, des opérations similaires sont exécutées avec du code adapté à la compatibilité.
Les entrées de registre sont ajoutées par le script, qui vérifie si les outils de chiffrement BitLocker Drive sont actifs et démarre le service de cryptage BitLocker Drive s'il ne s'exécute pas déjà.Le script désactive et supprime ensuite les protecteurs de bitlocker par défaut, les remplaçant par un mot de passe numérique pour éviter la récupération des clés.
Une clé de chiffrement unique à 64 caractères est générée à l'aide d'éléments aléatoires et de données spécifiques au système, converti en une chaîne sécurisée et utilisé pour activer BitLocker sur les disques.Les attaquants utilisent le domaine trycloudflare.com pour envoyer des demandes de publication chiffrées avec des informations système et la clé de chiffrement de leur serveur.
Pour couvrir ses pistes, le script se supprime, efface les journaux et modifie les paramètres du système avant de forcer un arrêt.Lors du redémarrage, la victime est confrontée à un écran Bitlocker sans options de récupération, les verrouillant efficacement de leurs données.

2024-05-28 10:00:00 | L'évolution des cybermenaces à l'ère de l'IA: défis et réponses The Evolution of Cyber Threats in the Age of AI: Challenges and Responses (lien direct) |
"In war, the importance of speed cannot be overstated. Swift and decisive actions often determine the outcome of battles, as delays can provide the enemy with opportunities to exploit weaknesses and gain advantages." - General Patton, "Leadership and Strategy in Warfare," Military Journal, 1945. Cybersecurity has become a battlefield where defenders and attackers engage in a constant struggle, mirroring the dynamics of traditional warfare. In this modern cyber conflict, the emergence of artificial intelligence (AI) has revolutionized the capabilities of traditionally asymmetric cyber attackers and threats, enabling them to pose challenges akin to those posed by near-peer adversaries.[1] This evolution in cyber threats demands a strategic response from organizations leveraging AI to ensure speed and intelligence in countering increasingly sophisticated attacks. AI provides force multiplication factors to both attackers and defenders. To wit, which ever side neglects the use of this new technology does so at its own peril. AI-Driven Evolution of Cyber Threats AI is playing a pivotal role in empowering cyber attackers and bridging the gap towards near-peer status with organizations in terms of cyber threats which, historically have been asymmetric in nature. The advancements in AI technologies have provided attackers with sophisticated tools and techniques that rival the defenses of many organizations. Several key areas highlight how AI is enabling the evolution of cyber threats: Sophisticated Attack Automation: AI-powered tools allow attackers to automate various stages of the attack lifecycle, from reconnaissance to exploitation.[2] This level of automation enables attackers to launch coordinated and sophisticated attacks at scale, putting organizations at risk of facing near-peer level threats in terms of attack complexity and coordination. Adaptive and Evolving Tactics: AI algorithms can analyze data and adapt attack tactics in real-time based on the defender\'s responses.[3] This adaptability makes it challenging for defenders to predict and defend against evolving attack strategies, mirroring the dynamic nature of near-peer adversaries who constantly adjust their tactics to overcome defenses. AI-Driven Social Engineering: AI algorithms can analyze vast amounts of data to craft highly convincing social engineering attacks, such as phishing emails or messages.[4] These AI-driven social engineering techniques exploit human vulnerabilities effectively, making it difficult for organizations to defend against such personalized and convincing attacks. AI-Powered Malware: Malware developers leverage AI to create sophisticated and polymorphic malware that can evade detection by traditional security solutions.[5] This level of sophistication in malware design and evasion techniques puts organizations at risk of facing near-peer level threats in terms of malware sophistication and stealthiness. AI-Enhanced Targeting: AI algorithms can analyze large datasets to identify specific targets within organizations, such as high-value assets or individuals with sensitive information.[6] This targeted approach allows attackers to focus their efforts on critical areas, increasing the effectiveness of their attacks and approaching the level of precision seen in near-peer threat actor operations. The combination of these AI-driven capabilities empowers cyber attackers to launch sophisticated, automated, and adaptive attacks that challenge organizations in ways previously seen only with near-peer adversaries in nation state attacks and warfare. Today, a single person, harnessing the power of AI can create a veritable army and provides force multiplication to the attackers. This puts organizations at an even greater defensive disadvantage than in years prior to the introduction of AI.

#### Targeted Industries - Government Agencies & Services ## Snapshot A previously unknown threat actor, Bitdefender Labs designated as "Unfading Sea Haze", has been targeting military and government entities in the South China Sea region since 2018, undetected until recently. Bitdefender researchers link its operations to Chinese geopolitical interests. ## Description "Unfading Sea Haze" attacks start with spear-phishing emails containing malicious ZIP archives and LNK files, deploying fileless malware via MSBuild. This fileless malware, named \'SerialPktdoor,\' serves as a backdoor program that provides the attackers with remote control over the compromised system. Additionally, the attackers employ scheduled tasks, local administrator account manipulation, and commercial Remote Monitoring and Management (RMM) tools like the Itarian RMM to gain a foothold on the compromised network. Once access is established, Unfading Sea Haze utilizes various tools such as a custom keylogger, info-stealer targeting data stored in web browsers, and Gh0stRAT malware variants to capture keystrokes, steal information, and maintain persistence. The threat actor also utilizes tools like Ps2dllLoader, \'SharpJSHandler,\' and a custom tool for monitoring and exfiltrating data from breached systems. More recent attacks have shown a shift to using the curl utility and the FTP protocol for data exfiltration, along with dynamically generated credentials that are changed frequently. ## Recommendations Recommendations to protect against Information stealers Microsoft recommends the following mitigations to reduce the impact of Information stealer threats. - Check your Office 365 email filtering settings to ensure you block spoofed emails, spam, and emails with malware. Use [Microsoft Defender for Office 365](https://learn.microsoft.com/microsoft-365/security/office-365-security/defender-for-office-365?ocid=magicti_ta_learndoc) for enhanced phishing protection and coverage against new threats and polymorphic variants. Configure Microsoft Defender for Office 365 to [recheck links on click](https://learn.microsoft.com/microsoft-365/security/office-365-security/safe-links-about?ocid=magicti_ta_learndoc) and [delete sent mail](https://learn.microsoft.com/microsoft-365/security/office-365-security/zero-hour-auto-purge?ocid=magicti_ta_learndoc) in response to newly acquired threat intelligence. Turn on [safe attachments policies](https://learn.microsoft.com/microsoft-365/security/office-365-security/safe-attachments-policies-configure?ocid=magicti_ta_learndoc) to check attachments to inbound email. - Encourage users to use Microsoft Edge and other web browsers that support [SmartScreen](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/web-protection-overview?ocid=magicti_ta_learndoc), which identifies and blocks malicious websites, including phishing sites, scam sites, and sites that host malware. - 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. - Enforce MFA on all accounts, remove users excluded from MFA, and strictly [require MFA](https://learn.microsoft.com/azure/active-directory/identity-protection/howto-identity-protection-configure-mfa-policy?ocid=magicti_ta_learndoc) from all devices, in all locations, at all times. - Enable passwordless authentication methods (for example, Windows Hello, FIDO keys, or Microsoft Authenticator) for accounts that support passwordless.

2024-05-24 17:17:36 | Longe de lune en utilisant un jeu de chars malveillant pour infecter les appareils Moonstone Sleet using malicious tank game to infect devices (lien direct) |
## Snapshot Since February 2024, Microsoft has observed Moonstone Sleet infecting devices using a malicious tank game called DeTankWar. In some cases, after gaining initial access via the tank game, Moonstone Sleet conducted lateral movement and extensive exfiltration of data from impacted organizations. The actor has shared the DeTankWar malware extensively via social media and through directly contacting organizations in the gaming, education, and software development sectors, suggesting the actor is putting intense effort behind this campaign. Customers can use Microsoft Defender XDR to detect activity related to this threat actor in their environments. Microsoft Defender for Endpoint detects many components of this activity, such as *Moonstone Sleet actor activity detected*, and Microsoft Defender Antivirus detects the malware execution with behavioral signatures. ## Activity Overview Since February 2024, Microsoft observed Moonstone Sleet infecting devices using a malicious tank game it developed. Moonstone Sleet sent the game to targets through messaging platforms such as LinkedIn and Telegram, phishing emails, and also spoofed the website of a well-known game maker to act as a download site. Once the ZIP file is downloaded, multiple malicious DLLs included in it are run upon launch of the game leading to connection to command-and-control (C2) infrastructure using Moonstone Sleet\'s YouieLoad, which is decrypted from one of the DLLs and in some cases subsequent hands-on-keyboard activity. Observed targets include employees of blockchain, trading, game development, and technology companies, as well as academics. These targets are globally located. #### Attack chain **Initial access** Moonstone Sleet often approaches its targets either through messaging platforms or by email. We have observed the threat actor presenting itself as a game developer seeking either investment or developer support. In these emails, Moonstone Sleet masquerades as a legitimate blockchain company or uses fake companies. Moonstone Sleet presents DeTankWar as a nonfungible token (NFT)-enabled, play-to-earn game available on Windows, Mac, and Linux.  *Figure 1. Example of a Moonstone Sleet DeTankWar spear phishing email* To bolster its superficial legitimacy, Moonstone Sleet has created a robust public campaign that includes the websites *detankwar\[.\]com* and *defitankzone\[.\]com*, Twitter accounts for the personas it uses to approach targets, and the game itself, which is alternately referred to as DeTankWar, DeFiTankWar, TankWarsZone, and DeTankLand.   *Figures 2 and 3. DeTankWar Twitter accounts*   *Figures 4 and 5. Pages from the DeTankWar website* In mid-March, Microsoft observed a homoglyph domain created by Moonstone Sleet to spoof a well-known game developer. This website offered a page on DeTankWar with both a download link and a link to the @detankwar1 X (Twitter) account.  *Figure 6. Elements on the page for DeTankWar on spoofed website* **Launch** Visitors to the DeTankWar website are prompted to download a compressed ZIP archive.

2024-05-24 01:09:17 | Rapport de CrimeWare: Acred, Scarletsaler et SYS01 Stealers Crimeware Report: Acrid, ScarletStealer, and Sys01 Stealers (lien direct) |
## Snapshot Kaspersky security researchers provide details on three distinct stealers: Acrid, ScarletStealer, and Sys01. These stealers exhibit varying levels of sophistication and global targeting, with specific geographic concentrations for each. ## Description Acrid is a new stealer that was found in December 2023. It is written in C++ for the 32-bit system and uses the "Heaven\'s Gate" technique to bypass certain security controls. ScarletStealer is a rather unique stealer as most of its stealing functionality is contained in other binaries that it downloads. ScarletStealer victims are mostly located in Brazil, Turkey, Indonesia, Algeria, Egypt, India, Vietnam, the USA, South Africa and Portugal. Sys01 (also known as “Album Stealer” or “S1deload Stealer”) is a relatively unknown stealer that has been around since at least 2022. Victims of this campaign were found all over the world, but most of them were located in Algeria. The stealer is distributed through a long chain of downloaders, where the last one is the Penguish downloader, and signed with a digital certificate. Unlike previous publicly disclosed versions of Sys01, the latest version of the stealer has split functionality. It now specifically steals Facebook-related data and sends stolen browser data to the C2. All three stealers have the typical functionality one might expect from a stealer, such as stealing browser data, stealing local cryptocurrency wallets, stealing files with specific names, and stealing credentials from installed applications. The danger posed by stealers lies in the consequences. This malware steals passwords and other sensitive information, which later can be used for further malicious activities causing great financial losses among other things. ## Microsoft Analysis In recent years, Microsoft has tracked the growing risk that infostealers pose to enterprise security. Infostealers are commodity malware used to steal information from a target device and send it to the threat actor. The popularity of this class of malware led to the emergence of an infostealer ecosystem and a new class of threat actors who leveraged these capabilities to conduct their attacks. Infostealers are advertised as a malware as a service (MaaS) offering – a business model where the developers lease the infostealer payload to distributers for a fee. Information stealers are versatile and can be distributed in various forms including through phishing email campaigns, malvertising, and trojanized software, games and tools. Typically, once the user downloads and launches the malicious payload, it establishes command and control (C2) connections with suspicious domains. Once infected, the infostealer attempts to collect and ultimately exfiltrate information from the system including files, browsers, internet-facing devices and applications to the C2 servers. ## Detections ### Microsoft Defender for Endpoint Alerts with the following titles in the security center can indicate threat activity on your network. These alerts, however, can be triggered by unrelated threat activity. - Information stealing malware activity - An executable loaded an unexpected dll - DLL search order hijack - Possible S1deload stealer activity ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. Check the recommendations card for the deployment status of monitored mitigations. - Check your Office 365 email filtering settings to ensure you block spoofed emails, spam, and emails with malware. Use Microsoft Defender for Office 365 for enhanced phishing protection and coverage against new threats and polymorphic variants.
