STOCKSTAY Another Day: The Latest Addition to Turla’s Intelligence Gathering Apparatus

Google Threat Intelligence Group has identified STOCKSTAY, a .NET backdoor continuously developed and deployed by Russia-linked Turla (FSB Center 16) since December 2022. The multi-component malware communicates via secure WebSocket connections and targets government and military organizations in Ukraine, as well as entities interested in Italian foreign policy. STOCKSTAY shares significant code overlaps with KAZUAR, particularly the K1MORPHER obfuscation mechanism. The threat actor employs academic and diplomatic lures, malicious RDP files, and compromised Ukrainian infrastructure for deployment. STOCKSTAY demonstrates environmental keying for configuration protection and operates at multiple operational stages. The malware's modular architecture separates C2 communication, task orchestration, and execution into distinct components, mirroring KAZUAR's design philosophy and indicating shared development resources within Turla's cyber espionage arsenal.

Kazuar si evolve: Secret Blizzard (Turla) trasforma il suo backdoor storico in una botnet P2P modulare invisibile

Il gruppo russo Secret Blizzard (Turla/FSB) ha trasformato il malware Kazuar in una botnet peer-to-peer con tre moduli distinti (Kernel, Bridge, Worker) e 150 parametri di configurazione. La nuova architettura usa un sistema di elezione del leader per ridurre al minimo il traffico verso i server C2, rendendo il rilevamento estremamente difficile.
