L'attaque présumée s'est produite contre le Parti social-démocrate (SPD).Leurs comptes de messagerie ont été compromis dans l'attaque. Cette saga de piratage a commencé il y a plus de deux ans pendant la guerre russe-Ukraine et elle a progressivement augmenté au cours du temps. comment il a commencé Un groupe appelé APT28, également connu sous le nom de Fancy Bear, qui aurait des liens avec le gouvernement russe, a été accusé d'avoir fait de nombreuses cyberattaques partout dans le monde, y compris en Allemagne et quelques entités tchèques. Russian Cyberattack sur l'Allemagne Ils ont trouvé un Vulnérabilité Dans Microsoft Outlook et l'utiliser pour entrer dans les e-mails SPD. La vulnérabilité, un CVE-2023-23397 zéro-jour, est un bogue d'escalade de privilège essentiel dans Outlook qui pourrait permettre aux attaquants d'accéder aux hachages net-ntlmv2, puis de les utiliser pour s'authentifier à l'aide d'une attaque de relais. Le gouvernement allemand dit que non seulement le SPD mais aussi les entreprises allemandes en défense et en aérospatiale. Il comprenait également des objectifs de technologie de l'information, ainsi que des choses liées à la guerre en Ukraine. Ces cyberattaques ont commencé vers mars 2022, après que la Russie ait envahi l'Ukraine. Le gouvernement allemand a allégué que le service de renseignement militaire de la Russie, Gru, était derrière ces attaques. Ils ont même convoqué un diplomate russe en réponse à ces accusations. La Russie a nié les allégations La Russie a nié les allégations et appelé les accusations comme & # 8220; non fondée et sans fondement & # 8221;.

Russia’s APT28 Hackers Exploited Windows Flaw To Deploy ‘GooseEgg’ Malware (lien direct)		 Microsoft a récemment révélé que le groupe de menaces russes & # 8220; APT28 & # 8243;utilisé un outil de piratage précédemment inconnu, «GooseEgg & # 8221;Pour exploiter la vulnérabilité Windows Print Spooler pour obtenir un accès élevé aux systèmes cibles et voler des informations d'identification et des informations. Selon l'équipe de renseignement des menaces de Redmond, APT28, également appelée Fancy Bear and Forest Blizzard (anciennement Strontium), utilise l'outil post-compromis depuis au moins juin 2020 et peut-être dès avril 2019Pour exploiter le CVE-2022-38028 (score CVSS: 7.8) Vulnérabilité dans Windows Print Spooler Service. Cet outil modifie un fichier de contraintes JavaScript et l'exécute avec des autorisations au niveau du système.

Microsoft a observé APT28 en utilisant GooseEgg dans le cadre des activités post-compromis contre diverses cibles, y compris les organisations gouvernementales, non gouvernementales, de l'éducation et des transports en Ukraine, en Europe occidentale et en Amérique du Nord. Bien que Gooseegg soit une application de lanceur simple, il peut engendrer d'autres applications sur la ligne de commande avec des autorisations élevées. Cela permet aux acteurs de menace de prendre en charge les activités malveillantes telles que l'exécution du code distant, l'installation d'une porte dérobée et le déplacement latéralement à travers des réseaux compromis. Les gouvernements américains et britanniques ont lié Forest Blizzard à l'unité 26165 de la Fédération de Russie \'s Military Intelligence Agency, la principale Direction du renseignement de l'état-major général des Forces armées de la Fédération de Russie (GRU). «Microsoft a observé qu'après avoir obtenu l'accès à un appareil cible, Forest Blizzard utilise GooseEgg pour élever les privilèges dans l'environnement.GooseEgg est généralement déployé avec un script de lot, que nous avons observé en utilisant le nom execute.bat et doit.bat .Ce script de lot écrit le fichier servtask.bat, qui contient des commandes pour enregistrer / compresser les ruches de registre.Le script de lot invoque l'exécutable de GooseEgg apparié et configure la persistance en tant que tâche planifiée conçue pour exécuter servtask.bat », lit le Advisory publié par Microsoft lundi.

RiskIQ.webp 2024-03-05 19:03:47 Rester en avance sur les acteurs de la menace à l'ère de l'IA
Staying ahead of threat actors in the age of AI (lien direct)		 ## 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 ★★

ProofPoint.webp 2023-12-05 05:00:40 TA422 \\ Soule d'exploitation dédiée - la même semaine après semaine
TA422\\'s Dedicated Exploitation Loop-the Same Week After Week (lien direct)		 Key takeaways  Since March 2023, Proofpoint researchers have observed regular TA422 (APT28) phishing activity, in which the threat actor leveraged patched vulnerabilities to send, at times, high-volume campaigns to targets in Europe and North America.  TA422 used the vulnerabilities as initial access against government, aerospace, education, finance, manufacturing, and technology sector targets likely to either disclose user credentials or initiate follow-on activity.  The vulnerabilities included CVE-2023-23397-a Microsoft Outlook elevation of privilege flaw that allows a threat actor to exploit TNEF files and initiate NTLM negotiation, obtaining a hash of a target\'s NTLM password-and CVE-2023-38831-a WinRAR remote code execution flaw that allows execution of “arbitrary code when a user attempts to view a benign file within a ZIP archive,” according to the NIST disclosure.  Overview  Starting in March 2023, Proofpoint researchers have observed the Russian advanced persistent threat (APT) TA422 readily use patched vulnerabilities to target a variety of organizations in Europe and North America. TA422 overlaps with the aliases APT28, Forest Blizzard, Pawn Storm, Fancy Bear, and BlueDelta, and is attributed by the United States Intelligence Community to the Russian General Staff Main Intelligence Directorate (GRU). While TA422 conducted traditional targeted activity during this period, leveraging Mockbin and InfinityFree for URL redirection, Proofpoint observed a significant deviation from expected volumes of emails sent in campaigns exploiting CVE-2023-23397-a Microsoft Outlook elevation of privilege vulnerability. This included over 10,000 emails sent from the adversary, from a single email provider, to defense, aerospace, technology, government, and manufacturing entities, and, occasionally, included smaller volumes at higher education, construction, and consulting entities. Proofpoint researchers also identified TA422 campaigns leveraging a WinRAR remote execution vulnerability, CVE-2023-38831.  Bar chart showing the breakdown of TA422 phishing activity from March 2023 to November 2023.  Please attend: CVE-2023-23397-test meeting In late March 2023, TA422 started to launch high volume campaigns exploiting CVE-2023-23397 targeting higher education, government, manufacturing, and aerospace technology entities in Europe and North America. TA422 previously used an exploit for CVE-2023-23397 to target Ukrainian entities as early as April 2022, according to open-source reporting by CERT-EU.  In the Proofpoint-identified campaigns, our researchers initially observed small numbers of emails attempting to exploit this vulnerability. The first surge in activity caught our attention partly due to all the emails pointing to the same listener server, but mostly due to the volume. This campaign was very large compared to typical state-aligned espionage campaign activity Proofpoint tracks. Proofpoint observed over 10,000 repeated attempts to exploit the Microsoft Outlook vulnerability, targeting the same accounts daily during the late summer of 2023. It is unclear if this was operator error or an informed effort to collect target credentials. TA422 re-targeted many of the higher education and manufacturing users previously targeted in March 2023. It is unclear why TA422 re-targeted these entities with the same exploit. Based upon the available campaign data, Proofpoint suspects that these entities are priority targets and as a result, the threat actor attempted broad, lower effort campaigns regularly to try and gain access.    Like the high-volume TA422 campaign Proofpoint researchers identified in March 2023, the late summer 2023 messages contained an appointment attachment, using the Transport Neutral Encapsulation Format (TNEF) file. The TNEF file used a fake file extension to masquerade as a CSV, Excel file, or Word document, and contained an UNC path directing traffic to an SMB listener being hosted on a likely compromised Ubiquiti router.

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

Trending Cyber News and Threat Intelligence Lockbit Ransomware Disguised as Copyright Claim E-mail Being Distributed (published: June 24, 2022) ASEC researchers have released their analysis of a recent phishing campaign, active since February 2022. The campaign aims to infect users with Lockbit ransomware, using the pretense of a copyright claim as the phishing lure. The phishing email directs the recipient to open the attached zip file which contains a pdf of the infringed material. In reality, the pdf is a disguised NSIS executable which downloads and installs Lockbit. The ransomware is installed onto the desktop for persistence through desktop change or reboot. Prior to data encryption, Lockbit will delete the volume shadow copy to prevent data recovery, in addition to terminating a variety of services and processes to avoid detection.

API Hammering makes use of a large volume of Windows API calls to delay the execution of malicious activity to trick sandboxes into thinking the malware is benign. Whilst BazarLoader has utilized the technique in the past, this new variant creates large loops of benign API using a new process. Encoded registry keys within the malware are used for the calls and the large loop count is created from the offset of the first null byte of the first file in System32 directory. Zloader uses a different form of API Hammering to evade sandbox detection. Hardcoded within Zloader are four large functions with many smaller functions within.

Jocker trojan operators add malicious code to legitimate apps and re-upload them to Google Store under different names. To avoid detection, malicious functionality won’t start until the trojan checks that it is available in the store. The malicious payload is split in up to four files. It can block or substitute anti-fraud scripts, and modify X-Requested-With header in an HTTP request. Another Android malware involved in subscription fraud, MobOk trojan, has additional functionality to bypass captcha. MobOk was seen in a malicious app in Google Store, but the most common infection vector is being spread by other Trojans such as Triada. Analyst Comment: Limit your apps to downloads from the official stores (Google Store for Android), avoid new apps with low number of downloads and bad reviews. Pay attention to the terms of use and payment. Avoid granting it too many permissions if those are not crucial to the app alleged function. Monitor your balance and subscription list.

Trending Cyber News and Threat Intelligence SocGholish and Zloader – From Fake Updates and Installers to Owning Your Systems (published: April 25, 2022) Cybereason researchers have compared trending attacks involving SocGholish and Zloader malware. Both infection chains begin with social engineering and malicious downloads masquerading as legitimate software, and both lead to data theft and possible ransomware installation. SocGholish attacks rely on drive-by downloads followed by user execution of purported browser installer or browser update. The SocGholish JavaScript payload is obfuscated using random variable names and string manipulation. The attacker domain names are written in reverse order with the individual string characters being put at the odd index positions. Zloader infection starts by masquerading as a popular application such as TeamViewer. Zloader acts as information stealer, backdoor, and downloader. Active since 2016, Zloader actively evolves and has acquired detection evasion capabilities, such as excluding its processes from Windows Defender and using living-off-the-land (LotL) executables. Analyst Comment: All applications should be carefully researched prior to installing on a personal or work machine. Applications that request additional permissions upon installation should be carefully vetted prior to allowing permissions. Additionally, all applications, especially free versions, should only be downloaded from trusted vendors.

Trending Cyber News and Threat Intelligence Lazarus Targets Chemical Sector (published: April 14, 2022) In January 2022, Symantec researchers discovered a new wave of Operation Dream Job. This operation, attributed to the North Korea-sponsored group Lazarus, utilizes fake job offers via professional social media and email communications. With the new wave of attacks, Operation Dream Job switched from targeting the defense, government, and engineering sectors to targeting South Korean organizations operating within the chemical sector. A targeted user executes an HTM file sent via a link. The HTM file is copied to a DLL file to be injected into the legitimate system management software. It downloads and executes the final backdoor: a trojanized version of the Tukaani project LZMA Utils library (XZ Utils) with a malicious export added (AppMgmt). After the initial access, the attackers gain persistence via scheduled tasks, move laterally, and collect credentials and sensitive information. Analyst Comment: Organizations should train their users to recognize social engineering attacks including those posing as “dream job” proposals. Organizations facing cyberespionage threats should implement a defense-in-depth approach: layering of security mechanisms, redundancy, fail-safe defense processes.

Trending Cyber News and Threat Intelligence 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.

Trending Cyber News and Threat Intelligence 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. Don’t be tricked to download Adobe Flash update, it was discontinued at the end of December 2020.

All victims are told to pay 0.01 Bitcoins, which is approximately $557.74, to get a password for their archived files. While the files are being locked, the Resource Monitor will display numerous '7z' processes which are the 7zip command-line executable. Analyst Comment: Attackers are using legitimate tools like 7zip to evade detections by traditional antiviruses. EDR solutions can help tracking suspicious command line arguments and process creations to potentially detect such attacks. Customers should use backup solutions to be able recover encrypted files.

Trending Cyber News and Threat Intelligence China’s ‘Hybrid War’: Beijing’s Mass Surveillance of Australia and the World for Secrets and Scandal (published: September 14, 2020) A database containing 2.4 million people has been leaked from a Shenzhen company, Zhenhua Data, believed to have ties to the Chinese intelligence service. The database contains personal information on over 35,000 Australians and prominent figures, and 52,000 Americans. This includes addresses, bank information, birth dates, criminal records, job applications, psychological profiles, and social media. Politicians, lawyers, journalists, military officers, media figures, and Natalie Imbruglia are among the records of Australians contained in the database. While a lot of the information is public, there is also non-public information contributing to claims that China is developing a mass surveillance system. Recommendation: Users should always remain vigilant about the information they are putting out into the public, and avoid posting personal or sensitive information online. Tags: China, spying US Criminal Court Hit by Conti Ransomware; Critical Data at Risk (published: September 11, 2020) The Fourth District Court of Louisiana, part of the US criminal court system, appears to have become the latest victim of the Conti ransomware. The court's website was attacked and used to steal numerous court documents related to defendants, jurors, and witnesses, and then install the Conti ransomware. Evidence of the data theft was posted to the dark web. Analysis of the malware by Emsisoft’s threat analyst, Brett Callow, indicates that the ransomware deployed in the attack was Conti, which has code similarity to another ransomware strain, Ryuk. The Conti group, believed to be behind this ransomware as a service, is sophisticated and due to the fact that they receive a large portion of the ransoms paid, they are motivated to avoid detections and continue to develop advanced attacking tools. This attack also used the Trickbot malware in its exploit chain, similar to that used by Ryuk campaigns. Recommendation: Defense in Depth, including vulnerability remediation and scanning, monitoring, endpoint protection, backups, etc. is key to thwarting increasingly sophisticated attacks. Ransomware attacks are particularly attractive to attackers due to the fact that each successful ransomware attack allows for multiple streams of income. The attackers can not only extort a ransom to decrypt the victim's files (especially in cases where the victim finds they do not have appropriate disaster recovery plans), but they can also monetize the exfiltrated data directly and/or use the data to aid in future attacks. This technique is increasingly used in supply chain compromises to build difficult to detect spearphishing attacks.

The IOCs related to these stories are attached to the Weekly Threat Briefing and can be used to check your logs for potential malicious activity. Figure 1 - IOC Summary Charts. These charts summarize the IOCs attached to this magazine and provide a glimpse of the threats discussed. Trending Cyber News and Threat Intelligence ‘Baka’ Javascript Skimmer Identified (published: September 6, 2020) Visa have issued a security alert based on identification of a new skimmer, named “Baka”. Based on analysis by Visa Payment Fraud Disruption, the skimmer appears to be more advanced, loading dynamically and using an XOR cipher for obfuscation. The attacks behind Baka are injecting it into checkout pages using a script tag, with the skimming code downloading from the Command and Control (C2) server and executing in memory to steal customer data. Recommendation: eCommerce site owners must take every step necessary to secure their data and safeguard their payment card information. Visa has also released best practices in the security advisory.

After receiving many tech support calls, the computer networks were shut down to prevent further spread of the ransomware, which led to a cecission in border crossings until systems were up again. The ransomware used in this attack is Netwalker ransomware, that left a ransom note demanding initalling $2 million, however when this wasn’t paid in the first week, the ransom increased to $4 million. Recommendation: Ransomware can potentially be blocked by using endpoint protection solutions (HIDS). Always keep your important files backed up following the 3-2-1 rule: have at least 3 different copies, on 2 different mediums, with 1 off-site. In the case of ransomware infection, the affected system must be wiped and reformatted. Other devices on the network should be checked for similar infections. Always check for a decryptor before considering payment; avoid payment at all costs. Ransomware should be reported to law enforcement agencies who are doing their best to track these actors and prevent ransom from being a profitable business for cyber criminals.
