ProofPoint.webp 2024-08-01 11:50:23 Menace Actor abuse des tunnels Cloudflare pour livrer des rats
Threat Actor Abuses Cloudflare Tunnels to Deliver RATs (lien direct)		 Key findings  Proofpoint has observed an increase in malware delivery via TryCloudflare Tunnel abuse.  The activity is financially motivated and delivers exclusively remote access trojans (RATs).   Since initial observation, the threat activity set behind the campaigns has modified tactics, techniques, and procedures in attempts to bypass detection and improve efficacy.  Proofpoint does not attribute this activity to a tracked TA, but research is ongoing.  Overview  Proofpoint is tracking a cluster of cybercriminal threat activity leveraging Cloudflare Tunnels to deliver malware. Specifically, the activity abuses the TryCloudflare feature that allows an attacker to create a one-time tunnel without creating an account. Tunnels are a way to remotely access data and resources that are not on the local network, like using a virtual private network (VPN) or secure shell (SSH) protocol.   First observed in February 2024, the cluster increased activity in May through July, with most campaigns leading to Xworm, a remote access trojan (RAT), in recent months.   In most campaigns, messages contain a URL or attachment leading to an internet shortcut (.URL) file. When executed, it establishes a connection to an external file share, typically via WebDAV, to download an LNK or VBS file. When executed, the LNK/VBS executes a BAT or CMD file that downloads a Python installer package and a series of Python scripts leading to malware installation. In some cases, file staging leverages the search-ms protocol handler to retrieve the LNK from a WebDAV share. Typically in campaigns, a benign PDF is displayed to the user to appear legitimate.    In June and July, nearly all observed campaigns delivered Xworm, but previous campaigns also delivered AsyncRAT, VenomRAT, GuLoader, and Remcos. Some campaigns will lead to multiple different malware payloads, with each unique Python script leading to the installation of a different malware.  Malware observed in related campaigns leveraging “trycloudflare” tunnels.   Campaign message volumes range from hundreds to tens of thousands of messages impacting dozens to thousands of organizations globally. In addition to English, researchers observed French, Spanish, and German language lures. Xworm, AsyncRAT, and VenomRAT campaigns are often higher volume than campaigns delivering Remcos or GuLoader. Lure themes vary, but typically include business-relevant topics like invoices, document requests, package deliveries, and taxes.   While the tactics, techniques and procedures (TTPs) of the campaigns remain consistent, the threat actor does appear to modify different parts of the attack chain to increase sophistication and defense evasion. For example, initial campaigns used little to no obfuscation in their helper scripts. The scripts often included detailed comments about the functionality of the code. However, this changed in June when the threat actors began to incorporate obfuscation in their code.  Helper script without obfuscation (May 2024 campaign example).  Helper script with obfuscation (June 2024 campaign example). Threat actor abuse of TryCloudflare tunnels became popular in 2023 and appears to be increasing among cybercriminal threat actors. Each use of TryCloudflare Tunnels will generate a random subdomain on trycloudflare[.]com, for example ride-fatal-italic-information[.]trycloudflare[.]com. Traffic to the subdomains is proxied through Cloudflare to the operators\' local server.  Campaign examples  AsyncRAT / Xworm Campaign 28 May 2024  Proofpoint observed a campaign on 28 May 2024 delivering AsyncRAT and Xworm. In this campaign, tax-themed messages contained URLs leading to a zipped .URL file. The campaign targeted organizations in law and finance and included less than 50 total messages.  28 May 2024 email lure using 2023 tax themes.   The .URL file pointed to a remote .LNK file. If executed, it led to a CMD helper script w Malware Threat ★★★

Mint Stealer: A Comprehensive Study of a Python-Based Information Stealer (lien direct)		 ## Snapshot Researchers at Cyfirma have identified Mint Stealer, an [information-stealing malware](https://sip.security.microsoft.com/intel-profiles/2296d491ea381b532b24f2575f9418d4b6723c17b8a1f507d20c2140a75d16d6) operating within a malware-as-a-service (MaaS) framework. Mint Stealer is designed to covertly exfiltrate a wide-range of sensitive data from compromised systems, including web browser data, cryptocurrency wallet details, gaming credentials, VPN client information, messaging app data, FTP client data, and more. ## Description Mint-stealer\'s capabilities include capturing system information, detecting debuggers and analysis tools, continuously capturing clipboard data through PowerShell commands, encrypting exfiltrated data, and communicating with its C2 server for updates and instructions.  Mint Stealer is created using the Nuitka Python compiler and relies on Python dynamic modules to support its functionality. The initial payload acts as a dropper, with the main payload hidden in a compressed form within the resources section of the executable. It uploads stolen data to free file-sharing websites and communicates with its command-and-control server (C2) for updates and instructions. The threat actor behind Mint Stealer is associated with another malware-selling website, cashout\[.\]pw, and offers hosting services that do not respect DMCA requests. ## 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. Often, 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. The new class of actors enabled by the infostealer ecosystem demonstrate that it is possible to gain initial access to an organization with minimal native malware development skills, by purchasing tools already available. Information stealers are versatile and can be distributed in various forms including through phishing email campaigns, malvertising, and trojanized software, games and tools. They can target a range of information like session tokens and cookies, saved passwords, financial information, and credentials for internet-facing systems and applications. ## Detections/Hunting Queries ### Microsoft Defender Antivirus Microsoft Defender Antivirus detects threat components as the following malware: - Trojan:Win32/Casdet ### Microsoft Defender for Endpoint Alerts with the following titles in the security center can indicate threat activity on your network: - Information stealing malware activity ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat.

Quarterly cyber threat report: MITRE ATT&CK framework trends in OSINT (April 2024 – June 2024) (lien direct)		 ## Snapshot This report presents an analysis of recent trends in cyber threats based on 111 articles published by threat researchers across the security community between April and June 2024. These articles are curated by Microsoft Threat Intelligence from across a number of trusted sources and included in Microsoft Defender Threat Intelligence as open source intelligence (OSINT) articles. The analysis focuses on the nearly 1,000 MITRE ATT&CK framework tags correlated to the content in each article. By distilling insights from these tags and the related intelligence, we can highlight prevalent tactics, techniques, and procedures (TTPs) observed in the cyber security landscape over the past quarter. This dataset is not exhaustive but represents a curated set of most high-profile cyber threat intelligence reporting from across the security community. When prioritizing cyber security efforts, it\'s essential to understand the trending TTPs observed in the wild. This knowledge helps defenders make informed decisions about the most effective strategies to implement, especially where to focus engineering efforts and finite resources. ## Activity Overview - **Initial access: Phishing**: Phishing remains a prevalent initial access method, mentioned in a third of reports, including spear-phishing attachments and links. The persistence of this technique underscores its effectiveness and the ongoing need for robust user education and email security measures. - **Defense evasion: Obfuscated files or information:** Over a third of reports highlighted the use of obfuscation techniques, such as dynamic API resolution and steganography, to evade detection. This trend is likely underpinned by factors such as the cybercrime market for obfuscating even basic credential theft malware as well as the growing sophistication in some malware to bypass traditional security measures. - **Command and control: Ingress tool transfer:** Ingress tool transfer was the most frequently referenced technique, involving the transfer of tools from an external system to a compromised one. Key threats driving the prevalence of this tactic included an increase in OSINT reporting on threat actors misusing the ms-appinstaller URI scheme (App Installer) to distribute malware. - **Execution: Command and scripting interpreter/PowerShell:** Execution through PowerShell was prominent, continuing its trend of broad adoption in attacks over the past decade. The widespread adoption of PowerShell to launch malicious code is in part due to numerous toolkits that have been developed to allow quick deployment of a wide range of attacks. - **Exfiltration: Exfiltration over C2 channel:** The most commonly referenced exfiltration method was over the command-and-control (C2) channel, highlighting the critical need for network monitoring and anomaly detection to identify and mitigate data breaches. The frequent reports on infostealers such as Lumma and DarkGate-commodity malware used to steal information from a target device and send it to the threat actor-are likely key drivers of this MITRE tag\'s prominence. - **Impact: Data encrypted for impact:** Ransomware involving data encryption was the most frequently observed impact technique, with LockBit and other groups exploiting vulnerabilities. The use of Bring Your Own Vulnerable Driver (BYOVD) tactics, such as Warp AV Killer, remained common. #### Initial access: Phishing Phishing remains a significant initial access method in open-source research, with a third of the reports mentioning its use. This includes both spear-phishing attachments and spear-phishing links. Phishing involves deceptive attempts to trick individuals into divulging sensitive information or installing malicious software, often through seemingly legitimate emails. The persistence of this technique underscores its effectiveness and the ongoing need for robust user education and email security measures. Phishing remains a dominant method for initial access in cyber threat landscapes due to its effective Ransomware Spam Malware Tool Vulnerability Threat Legislation Prediction Cloud ★★★

Donot APT Group Targeting Pakistan (lien direct)		 #### Targeted Geolocations - United States - Eastern Europe - Northern Europe - Western Europe - Southern Europe - Central Asia - East Asia - South Asia - Southeast Asia #### Targeted Industries - Government Agencies & Services - Information Technology - Defense Industrial Base ## Snapshot Rewterz published a profile on APT-C-35, also known as the Donot APT group, a cyber espionage group active since at least 2013. ## Description The Donot APT group is known to target government and military organizations, as well as companies in the aerospace, defense, and high-tech industries. Their activities have been observed in several regions, including the United States, Europe, and Asia. The Donot group\'s motivations are information theft and espionage. The group is known for targeting Pakistani users with Android malware named StealJob, disguised under the name “Kashmiri Voice” to steal confidential information and intellectual property. In July 2022, they used Comodo\'s certificate to sign their spyware, demonstrating their high level of technical skill. The Donot APT group employs various tactics such as spear-phishing emails, malware, and custom-developed tools, often using third-party file-sharing websites for malware distribution. They are well-funded and use sophisticated techniques to evade detection, including encryption and file-less malware.  ## Additional Analysis According to a number of additional sources, Donot group is likely [linked to the Indian government](https://socradar.io/apt-profile-apt-c-35-donot-team/). Initial access to victim environments is typically achieved through phishing campaigns and the group has been observed exploiting vulnerabilities in Microsoft Office, including [CVE-2018-0802](https://security.microsoft.com/intel-explorer/cves/CVE-2018-0802/), [CVE-2017-0199](https://security.microsoft.com/intel-explorer/cves/CVE-2017-0199/), and [CVE-2017-8570](https://security.microsoft.com/intel-explorer/cves/CVE-2017-8570/).  Donot group is a persistent and consistent actor.

RiskIQ.webp 2024-07-31 15:03:11 Les fausses mises à jour du navigateur déploient un logiciel Asyncrat et malveillant BOINC
Fake Browser Updates Deploy AsyncRAT and Malicious BOINC Software (lien direct)		 ## Snapshot Researches at Huntress identified new behaviors associated with SocGholish, or FakeUpdates, malware. Typically, infections start when a user visits a compromised website and downloads a fake browser update, which executes malicious code to download further malware. . ## Description Initial access involves a malicious JavaScript file that downloads subsequent stages of the attack. In this case, two separate chains were identified: one leading to a fileless AsyncRAT installation and the other to a malicious BOINC (Berkeley Open Infrastructure Network Computing Client) installation. The AsyncRAT chain involved several stages with obfuscated PowerShell scripts and anti-VM techniques, eventually leading to a connection to a command and control (C2) server. The BOINC chain involved dropping multiple files, creating directories and scheduled tasks, and renaming executables to disguise their malicious intent. The BOINC software, typically used for legitimate distributed computing projects, was configured to connect to malicious servers, enabling threat actors to collect data and execute tasks on infected hosts. Persistence was maintained through scheduled tasks, and the use of BOINC in this context is relatively unusual. Both chains showed similarities with previous SocGholish activities, such as using fake browser updates and PowerShell scripts. The new campaigns utilized recently registered domains and shared infrastructure noted by other security researchers. ## Microsoft Analysis Microsoft researchers have investigated multiple incidents involving fake software updates served by the SocGholish malware distribution framework. [SocGholish](https://security.microsoft.com/intel-profiles/7e30959d011aa33939afaa2477fd0cd097cee346fa3b646446a6b1e55f0c007f) is an attack framework that malicious attackers have used since at least 2020. The attacker framework entices users to install fake software updates that eventually let attackers infiltrate target organizations. SocGholish can be tweaked to deliver any payload an attacker chooses. Threat actor, [Mustard Tempest](https://security.microsoft.com/intel-profiles/79a9547522d81fe6c1f5e42d828009656892f3976c547360db52c33f0ba16db9?tab=tradeCraft), uses SocGholish/FakeUpdates as their primary technique to gain intial access.

It is designed to evade detection and is often used by attackers to gain unauthorized access to a victim\'s system. AsyncRAT is written in .NET and is capable of running on Windows machines. It can perform various malicious activities such as keylogging, file stealing, and ransomware deployment. Its name comes from its use of asynchronous programming techniques, which allow it to carry out multiple tasks simultaneously without blocking the program\'s main thread.

Are Ransomware Attacks Still a Growing Threat in 2024? (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.  Ransomware attacks continue to pose a growing threat to organizations as it has emerged as the number one threat, affecting 66% of organizations in 2023 and pulling over $1 billion from the victims. These attacks have increased in frequency and sophistication, resulting in significant financial loss, operation disruption, theft of sensitive data, and reduced productivity rates. Also, it damages the organization\'s reputation and results in the loss of customer trust and compliance violations. An organization needs a comprehensive protection strategy to reduce the frequency of these attacks and the risks they pose. Ransomware Business Model: How These Attacks Are Evolving? In the past, ransomware attacks mainly relied on phishing emails, remote desktop protocol exploits, and vulnerable ports to increase their chances of success. Additionally, these attacks employ evasion techniques to bypass traditional security measures like firewalls or antivirus software. These methods have resulted in famous attacks like WannaCry, TeslaCrypt, and NotPetya. With time, ransomware attackers have evolved and have become more sophisticated, targeted, and profitable for cybercriminals. Below is an insight into the latest trends that hackers adopt to launch a successful ransomware attack: Exploiting Zero-Day Vulnerabilities The shift in ransomware gangs and their sophisticated tactics and procedures (TTPs) raise the number of ransomware attacks. . Previously, REvil, Conti, and LockBit were the famous ransomware gangs, but now Clop, Cuban, and Play are gaining immense popularity by employing advanced hacking techniques like zero-day vulnerabilities. Sophos\'s State of Ransomware 2024 revealed exploited vulnerabilities as the root cause of ransomware attacks. The Clop ransomware gang has used the zero-day vulnerability in the MOVEit Transfer platform to steal the sensitive data of different organizations. This group also targeted the GoAnywhere zero-day vulnerability in January 2023, affecting 130 organizations, and exploited the Accellion FTA servers in 2020. Similarly, Cuban and Play used the same attacking technique to compromise the unpatched Microsoft Exchange servers. Double and Triple Extortion Another reason for the rise in ransomware attacks is the introduction of the double or triple extortion technique. Cybersecurity firm Venafi reported that 83% of ransomware attacks included multiple ransom demands in 2022. Cybercriminals encrypt the data, exfiltrate sensitive information, and threaten to release it or sell it on the dark web if the ransom is not paid in a double extortion scheme.

SideWinder employs spear-phishing emails using familiar logos and themes to lure victims into opening malicious documents, which exploit vulnerabilities in Microsoft Office to gain access to systems. The group\'s objective is believed to be espionage and intelligence gathering, consistent with its past campaigns targeting military, government, and business entities in South Asia. The malicious documents use visual bait, such as fake port authority letters, to provoke fear and urgency, leading victims to download malware. The documents exploit a known vulnerability ([CVE-2017-0199](https://security.microsoft.com/intel-explorer/cves/CVE-2017-0199/)) in Microsoft Office, relying on outdated or unpatched systems to deliver their payload. Once opened, the documents download additional malicious files that execute shellcode to ensure the system is not a virtual environment, before proceeding with further stages of the attack.

A campaign targeting BBVA bank customers distributed the Remcos RAT under the guise of a CrowdStrike Hotfix, while the pro-Iranian hacktivist group Handala used similar tactics against Israeli companies. These attacks, stemming from a logic error in a channel file update, have significantly impacted millions of Windows systems across various sectors. ## Description AnyRun has identified the exploitation of CrowdStrike\'s update issue by threat actors, including phishing emails and malware campaigns targeting organizations with data wipers and remote access tools. Phishing emails have been observed attempting to take advantage of the disruption, with a malware campaign targeting BBVA bank customers offering a fake CrowdStrike Hotfix update that installs the Remcos RAT. The pro-Iranian hacktivist group Handala has also leveraged the situation by sending phishing emails that impersonate CrowdStrike to Israeli companies to distribute the data wiper. Additionally, attackers are distributing a data wiper under the pretense of delivering an update from CrowdStrike, decimating systems by overwriting files with zero bytes and reporting it over Telegram. The defect in CrowdStrike\'s software update had a massive impact on Windows systems at numerous organizations, making it too good an opportunity for cybercriminals to pass. The cause of the outage was identified as a channel file update to Windows hosts triggering a logic error, leading to a crash.

By manipulating the Selenium WebDriver API, threat actors establish a reverse shell, drop a custom XMRig miner, and use compromised Selenium node workloads as intermediate command and control servers (C2) for subsequent infections and mining pool proxies. The campaign targets older versions of Selenium but is also possible on more recent versions, potentially evading detection by targeting less maintained and monitored instances.  ## Additional Analysis [XMRig miner](https://www.checkpoint.com/cyber-hub/threat-prevention/what-is-malware/xmrig-malware/) is a popular open-source software designed for mining cryptocurrencies, particularly Monero (XMR). Developed in C++, XMRig is efficient and versatile, supporting various algorithms, mining pools, and running on multiple platforms like Windows, Linux, and macOS. However, it has been widely misused by cybercriminals who deploy it through malware to hijack the computing resources of unsuspecting victims, a practice known as cryptojacking. This unauthorized use of systems significantly degrades performance, increases energy consumption, and can cause hardware damage over time. Due to its frequent abuse in malicious campaigns, XMRig miner has become a focal point in discussions about cybersecurity threats related to resource hijacking and cryptomining. ## References [SeleniumGreed: Threat actors exploit exposed Selenium Grid services for Cryptomining](https://www.wiz.io/blog/seleniumgreed-cryptomining-exploit-attack-flow-remediation-steps).

Le JavaScript a masqué son code malveillant dans un véritable code jQuery pour échapper à la détection.Lorsque l'utilisateur a cliqué sur le bouton de téléchargement, le site a exécuté une fonction pour télécharger un fichier exécutable portable déguisé.Le programme d'installation, qui est apparu le 20 juillet 2024, avait un horodatage aligné avec la mise à jour du capteur, suggérant l'utilisation de l'horodatage pour éviter la détection. Le programme d'installation a incité les utilisateurs à saisir un mot de passe spécifique "serveur backend", probablement connu uniquement des cibles, indiquant une attaque très ciblée.Crowdstrike Intelligence a évalué avec une grande confiance que les attaquants se sont concentrés sur les clients germanophones touchés par le problème du capteur Falcon et ont utilisé des techniques avancées antiformes, notamment l'enregistrement des sous-domaines sous un registraire légitime et le contenu des installateurs. ## Analyse supplémentaire  Les acteurs du cybermenace exploitent les événements actuels pour perpétrer une activité malveillante car ces situations créent souvent de la confusion et de l'urgence, rendant les individus et les organisations plus vulnérables à la tromperie.Ils capitalisent sur l'intérêt accru et l'attention entourant de tels événements pour augmenter la probabilité que leurs tentatives de phishing et d'autres attaques réussissent.En alignant leurs campagnes malveillantes avec des incidents ou des mises à jour bien connues, les acteurs de la menace peuvent plus facilement masquer leurs intentions et attirer les victimes pour compromettre involontairement leur sécurité.  Cette campagne de phishing ciblant les clients germanophones est le dernier exemple de cyberattaques exploitant le chaos de la mise à jour de Falcon de Crowdsstrike.Les rapports antérieurs d'activité malveillante lors des pannes incluent [les essuie-glaces de données réparties par le groupe hacktiviste pro-iranien handala] (https://www.bleepingcomputer.com/news/security/fake-crowdstrike-fixes-target-companies-with-malware-data-wipers/), [HijackLoader dropping Remcos Remote Access Trojan](https://x.com/anyrun_app/status/1814567576858427410) disguised as a CrowdStrike hotfix, and information stealer[Daolpu] (https://www.crowdstrike.com/blog/fake-recovery-manUAL-UND-TO-DIVER-UNDENDIFIED SECELER /) Se propager par des e-mails de phishing se faisant passer pour un outil de récupération. ## Recommandations Microsoft recommande les atténuations suivantes pour réduire l'impact de cette menace. - Allumez [Protection en livraison du cloud] (https://learn.microsoft.com/en-us/defender-endpoint/linux-preférences) dans Microsoft Defender Antivirus ou l'équivalent de votre produit antivirus pour couvrir rapidement les outils d'attaquant en évolution et et et les outils d'attaquant en évolution rapide ettechniques.Les protections d'apprentissage automatique basées sur le cloud bloquent la majorité des menaces nouvelles et inconnues. - Exécuter [EDR en mode bloc] (https://learn.microsoft.com/microsoft-365/security/defender-endpoint/edr-in-block-mode?view=o365-worldwide?ocid=Magicti_TA_LearnDoc)Le défenseur du point f Ransomware Malware Tool Threat

Mandiant.webp 2024-07-29 14:00:00 Unc4393 entre doucement dans la nuit silencieuse
UNC4393 Goes Gently into the SILENTNIGHT (lien direct)		 Written by: Josh Murchie, Ashley Pearson,  Joseph Pisano,  Jake Nicastro,  Joshua Shilko, Raymond Leong
  Overview In mid-2022, Mandiant\'s Managed Defense detected multiple intrusions involving QAKBOT, leading to the deployment of BEACON coupled with other pre-ransomware indicators. This marked Mandiant\'s initial identification of UNC4393, the primary user of BASTA ransomware. Mandiant has responded to over 40 separate UNC4393 intrusions across 20 different industry verticals. While healthcare organizations have not traditionally been a focus for UNC4393, several breaches in the industry this year indicate a possible expansion of their interests. However, this represents only a fraction of the cluster\'s victims, with the Black Basta data leak site purporting over 500 victims since inception. Over the course of this blog post, Mandiant will detail the evolution of UNC4393\'s operational tactics and malware usage throughout its active lifespan, with a focus on the period following the QAKBOT botnet takedown. We will highlight the cluster\'s transition from readily available tools to custom malware development as well as its evolving reliance on access brokers and diversification of initial access techniques. UNC4393 intrusion lifecycle Figure 1: UNC4393 intrusion lifecycle Attribution and Targeting UNC4393 is a financially motivated threat cluster, and the primary user of BASTA ransomware, tracked since mid-2022 but likely active since early 2022 based on activity on the BASTA DLS.  The group has overwhelmingly leveraged initial access gained via UNC2633 and UNC2500 QAKBOT botnet infections to deploy BASTA ransomware. QAKBOT is typically distributed via phishing emails containing malicious links or attachments. In some cases, HTML smuggling has also been used to distribute ZIP files containing IMG files that house LNK files and QAKBOT payloads.  Mandiant suspects BASTA operators maintain a private or small, closed-invitation affiliate model whereby only trusted third-party actors are provided with use of the BASTA encryptor. Unlike traditional ransomware-as-a-service (RaaS), BASTA is not publicly marketed and its operators do not appear to actively recruit affiliates to deploy the ransomware. Instead, they focus on acquiring initial access via partnerships or purchases in underground communities. This deviates from traditional RaaS models, which focus on the ransomware development and related services such as the data leak site (DLS) that are provided to affiliates in exchange for directly distributing the ransomware. While UNC4393 is the only currently active threat cluster deploying BASTA that Mandiant tracks, we cannot rule out the possibility that other, vetted threat actors may also be given access to the encrypter. The hundreds of BASTA ransomware victims claimed on the DLS appear credible due to UNC4393\'s rapid operational tempo. With a median time to ransom of approximately 42 hours, UNC4393 has demonstrated p		 Ransomware Malware Tool Threat Prediction Medical Cloud
