AlienVault OTX Malware

UNG0901, a threat group targeting Russian aerospace and defense sectors, has been discovered conducting a spear-phishing campaign against the Voronezh Aircraft Production Association. The operation, dubbed 'CargoTalon', utilizes a custom DLL implant called EAGLET, which is disguised as a ZIP file containing transport documents. The infection chain involves a malicious LNK file that executes the EAGLET implant, which then establishes communication with a command-and-control server for remote access and data exfiltration. The campaign employs sophisticated tactics, including decoy documents related to Russian logistics operations, and shows similarities with another threat group known as Head Mare. The attackers' motivation appears to be espionage against Russian governmental and non-governmental entities.

Operation Cargotalon is a targeted cyber espionage campaign attributed to the threat group UNG0901, focusing on the Russian aerospace and defense sector, specifically targeting the Voronezh Aircraft Production Association. The attackers employ a spear-phishing vector, delivering a malicious LNK file disguised as a ZIP archive containing transport documents, which when executed, loads a custom DLL implant named EAGLET. This implant establishes a covert command-and-control (C2) channel to facilitate remote access and data exfiltration. The campaign uses sophisticated social engineering techniques, including decoy documents related to Russian logistics operations to increase the likelihood of victim interaction. The implant leverages multiple tactics and techniques mapped to MITRE ATT&CK, such as T1218.011 (signed binary proxy execution), T1566.001 (spear-phishing attachment), T1082 (system information discovery), T1005 (data from local system), T1036 (masquerading), T1482 (domain trust discovery), T1041 (exfiltration over C2 channel), T1059.001 (command and scripting interpreter: PowerShell), T1537 (transfer data to cloud account), and T1071.001 (application layer protocol: Web protocol). The operation shows similarities with another group known as Head Mare, suggesting possible shared tooling or tactics. The primary motivation appears espionage-driven, aiming to gather sensitive information from Russian aerospace and defense entities. No known exploits in the wild or affected software versions are specified, indicating a targeted, manual campaign rather than widespread automated exploitation. The medium severity rating reflects the targeted nature and potential impact on confidentiality and integrity of sensitive defense information.
