2024-07-29 10:58:35 | Weekly OSINT Highlights, 29 July 2024 (lien direct) | ## Snapshot Key trends from last week\'s OSINT reporting include novel malware, such as Flame Stealer and FrostyGoop, the compromise of legitimate platforms like Discord and GitHub, and state-sponsored threat actors conducting espionage and destructive attacks. Notable threat actors, including Russian groups, Transparent Tribe, FIN7, and DPRK\'s Andariel, are targeting a wide range of sectors from defense and industrial control systems to financial institutions and research entities. These attacks exploit various vulnerabilities and employ advanced evasion techniques, leveraging both traditional methods and emerging technologies like AI-generated scripts and RDGAs, underscoring the evolving and persistent nature of the cyber threat landscape. ## Description 1. [Widespread Adoption of Flame Stealer](https://sip.security.microsoft.com/intel-explorer/articles/f610f18e): Cyfirma reports Flame Stealer\'s use in stealing Discord tokens and browser credentials. Distributed via Discord and Telegram, this malware targets various platforms, utilizing evasion techniques like DLL side-loading and data exfiltration through Discord webhooks. 2. [ExelaStealer Delivered via PowerShell](https://sip.security.microsoft.com/intel-explorer/articles/5b4a34b0): The SANS Technology Institute Internet Storm Center reported a threat involving ExelaStealer, downloaded from a Russian IP address using a PowerShell script. The script downloads two PE files: a self-extracting RAR archive communicating with "solararbx\[.\]online" and "service.exe," the ExelaStealer malware. The ExelaStealer, developed in Python, uses Discord for C2, conducting reconnaissance activities and gathering system and user details. Comments in Russian in the script and the origin of the IP address suggest a Russian origin. 3. [FrostyGoop Disrupts Heating in Ukraine](https://sip.security.microsoft.com/intel-explorer/articles/cf8f8199): Dragos identified FrostyGoop malware in a cyberattack disrupting heating in Lviv, Ukraine. Linked to Russian groups, the ICS-specific malware exploits vulnerabilities in industrial control systems and communicates using the Modbus TCP protocol. 4. [Rhysida Ransomware Attack on Private School](https://sip.security.microsoft.com/intel-explorer/articles/4cf89ad3): ThreatDown by Malwarebytes identified a Rhysida ransomware attack using a new variant of the Oyster backdoor. The attackers used SEO-poisoned search results to distribute malicious installers masquerading as legitimate software, deploying the Oyster backdoor. 5. [LLMs Used to Generate Malicious Code](https://sip.security.microsoft.com/intel-explorer/articles/96b66de0): Symantec highlights cyberattacks using Large Language Models (LLMs) to generate malware code. Phishing campaigns utilize LLM-generated PowerShell scripts to download payloads like Rhadamanthys and LokiBot, stressing the need for advanced detection against AI-facilitated attacks. 6. [Stargazers Ghost Network Distributes Malware](https://sip.security.microsoft.com/intel-explorer/articles/62a3aa28): Check Point Research uncovers a network of GitHub accounts distributing malware via phishing repositories. The Stargazer Goblin group\'s DaaS operation leverages over 3,000 accounts to spread malware such as Atlantida Stealer and RedLine, targeting both general users and other threat actors. 7. [Crimson RAT Targets Indian Election Results](https://sip.security.microsoft.com/intel-explorer/articles/dfae4887): K7 Labs identified Crimson RAT malware delivered through documents disguised as "Indian Election Results." Transparent Tribe APT, believed to be from Pakistan, targets Indian diplomatic and defense entities using macro-embedded documents to steal credentials. 8. [AsyncRAT Distributed via Weaponized eBooks](https://sip.security.microsoft.com/intel-explorer/articles/e84ee11d): ASEC discovered AsyncRAT malware distributed through weaponized eBooks. Hidden PowerShell scripts within these eBooks trigger the AsyncRAT payload, which uses obfuscation and anti-detection techniques to exfiltrate data. | Ransomware Data Breach Spam Malware Tool Vulnerability Threat Legislation Mobile Industrial Medical | APT 28 APT 36 | |

2023-11-10 17:52:00 | Des pirates russes Sandworm provoquent une panne de courant en Ukraine au milieu des frappes de missiles Russian Hackers Sandworm Cause Power Outage in Ukraine Amidst Missile Strikes (lien direct) |
Les pirates russes notoires connus sous le nom de Sandworm ont ciblé une sous-station électrique en Ukraine l'année dernière, provoquant une brève panne de courant en octobre 2022.
Les résultats proviennent du mandiant de Google \\, qui a décrit le hack comme une "cyberattaque multi-événements" en tirant parti d'une nouvelle technique pour avoir un impact sur les systèmes de contrôle industriel (CI).

The notorious Russian hackers known as Sandworm targeted an electrical substation in Ukraine last year, causing a brief power outage in October 2022. The findings come from Google\'s Mandiant, which described the hack as a "multi-event cyber attack" leveraging a novel technique for impacting industrial control systems (ICS).

fin 2022, Mandiant a répondu à un incident de cyber-physique perturbateur dans lequel l'acteur de menace lié à la Russie a ciblé une organisation d'infrastructure critique ukrainienne.Cet incident était une cyberattaque multi-événements qui a exploité une nouvelle technique pour avoir un impact sur les systèmes de contrôle industriel (CI) / technologie opérationnelle (OT).L'acteur a d'abord utilisé le niveau OT vivant des techniques terrestres (LOTL) pour déclencher probablement les disjoncteurs de sous-station de la victime, provoquant une panne de courant imprévue qui coïncidait avec les frappes de missiles de masse sur les infrastructures critiques à travers l'Ukraine.Sandworm plus tard
In late 2022, Mandiant responded to a disruptive cyber physical incident in which the Russia-linked threat actor Sandworm targeted a Ukrainian critical infrastructure organization. This incident was a multi-event cyber attack that leveraged a novel technique for impacting industrial control systems (ICS) / operational technology (OT). The actor first used OT-level living off the land (LotL) techniques to likely trip the victim\'s substation circuit breakers, causing an unplanned power outage that coincided with mass missile strikes on critical infrastructure across Ukraine.

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