Déballage de l\\\\\\\\\\'attaque de ransomware de verrouillage de verrouillage (lien direct) |
## Instantané
La réponse aux incidents de Cisco Talos a observé le groupe de ransomwares de verrouillage se livrant à des attaques de chasse au grand jeu et à une double extorsion, ciblant des secteurs tels que les soins de santé, la technologie, le gouvernement aux États-Unis et la fabrication en Europe depuis son émergence en septembre 2024.
## Description
Le groupe emploie une chaîne de livraison multi-composants, lançant son attaque via un site Web légitime compromis qui incite les victimes à télécharger un faux parcours de mise à jour du navigateur. Cet exécutable est un outil d'accès à distance (RAT) qui établit la persistance, collecte les informations système et communique avec un serveur de commande et de contrôle (C2). Les attaquants utilisent également un voleur d'identification, Keylogger et des outils comme AnyDesk, Putty et Azure Storage Explorer pour le mouvement latéral et l'exfiltration des données.
Le ransomware de verrouillage, qui a à la fois des variantes Windows et Linux, chiffre les fichiers et ajoute l'extension «.Interlock», tout en évitant le chiffrement de certains dossiers système et extensions de fichiers. La variante Windows utilise un cryptage de chaînage de blocs de chiffre d'affaires (CBC) et la variante Linux utilise le cryptage CBC ou RSA. Le ransomware établit la persistance en créant une tâche quotidienne et peut se supprimer après le cryptage. Une note de rançon est configurée pour s'afficher pendant la connexion interactive à l'aide d'objets de stratégie de groupe, exigeant une réponse dans les 96 heures pour éviter les fuites de données et la notification médiatique. Talos IR note que les ransomwares de verrouillage peuvent avoir des connexions avec les opérateurs ou développeurs de ransomwares Rhysida, suggérés par des similitudes de tactique, de techniques et de procédures (TTPS), ainsi que les comportements des binaires des encryptateurs de ransomware. Les deux groupes utilisent Azcopy pour l'exfiltration des données et fournissent des notes de rançon qui offrent de l'aide plutôt que des menaces, indiquant une tendance de diversification et de collaboration entre les groupes de ransomwares.

Les Poissons Jumpy s'engagent dans des ransomwares de jeu Jumpy Pisces Engages in Play Ransomware (lien direct) |
## Snapshot
Unit 42 has identified the North Korean state-sponsored threat group Jumpy Pisces, also known as Andariel and Onyx Sleet, engaging in a recent ransomware incident through a potential collaboration with the Play ransomware group.
## Description
Historically known for cyberespionage, financial crime, and ransomware attacks, Jumpy Pisces (Which Microsoft tracks as [Onyx Sleet](https://security.microsoft.com/intel-profiles/03ced82eecb35bdb459c47b7821b9b055d1dfa00b56dc1b06f59583bad8833c0)) gained initial access to a victim\'s network in early September 2024 through a compromised user account. They maintained persistence and moved laterally using the open-source tool Sliver, their custom malware DTrack, and other tools such as a customized version of Mimikatz for credential dumping, a tool for creating privileged user accounts with RDP enabled, and a trojanized binary for stealing browser data. These tools communicated with a command-and-control server until the deployment of [Play Ransomware](https://security.microsoft.com/intel-profiles/5052c3d91b03a0996238bf01061afdd101c04f1afb7aeda1fc385a19b4f1b68e).
During the period from May to September 2024, the attackers executed various activities, including credential harvesting and privilege escalation, and notably uninstalled endpoint detection and response (EDR) sensors before deploying the ransomware. The use of additional tools like TokenPlayer for Windows access token abuse and PsExec was also observed. The nature of Jumpy Pisces ([Onyx Sleet](https://security.microsoft.com/intel-profiles/03ced82eecb35bdb459c47b7821b9b055d1dfa00b56dc1b06f59583bad8833c0))\'s involvement with [Play Ransomware](https://security.microsoft.com/intel-profiles/5052c3d91b03a0996238bf01061afdd101c04f1afb7aeda1fc385a19b4f1b68e) is not definitively clear, as they could be acting as an affiliate or as an Initial Access Broker (IAB) by selling network access to Play ransomware actors. This incident marks a significant development in cyber threats, indicating a convergence of state-sponsored and underground ransomware operations and potentially signaling a trend where North Korean threat groups increasingly participate in global ransomware campaigns.
## Microsoft Analysis and Additional OSINT Context
The threat actor that Microsoft tracks as Onyx Sleet is a North Korea-affiliated activity group. First observed by Microsoft in 2014, Onyx Sleet has conducted cyber espionage through numerous campaigns aimed at global targets with the goal of intelligence gathering. More recently, it has expanded its goals to include financial gain. This threat actor operates with an extensive set of custom tools and malware, and regularly evolves its toolset to add new functionality and to evade detection, while keeping a fairly uniform attack pattern. Onyx Sleet\'s ability to develop a spectrum of tools to launch its tried-and-true attack chain makes it a persistent threat, particularly to targets of interest to North Korean intelligence, like organizations in the defense, engineering, and energy sectors. On July 25, 2024, the United States Department of Justice (DOJ) indicted an individual linked to the North Korean threat actor that Microsoft tracks as Onyx Sleet. Microsoft Threat Intelligence collaborated with the Federal Bureau of Investigation (FBI) in tracking activity associated with Onyx Sleet. Onyx Sleet is tracked by other security companies as SILENT CHOLLIMA, Andariel, DarkSeoul, Stonefly, TDrop2, Jumpy Pisces, and APT45.
Microsoft tracks campaigns related to Onyx Sleet and directly notifies customers who have been targeted or compromised, providing them with the necessary information to help secure their environments. Microsoft Defender for Endpoint detects this activity as Onyx Sleet activity group. Microsoft Defender customers can turn on attack surface reduction rules to prevent common attack techniques such as blocking executable files from running unless they meet a prevalence, age, or trusted list criterion, blocking the launch of potentially obfuscated |
