Silent Lynx Hits CIS Governments With WinRAR Flaw

Silent Lynx (UAT-6275 / TAG-193) is a cyber-espionage actor targeting government organizations across the Commonwealth of Independent States. From June 2025 through August 2026, the group used four infection chains, including macro-enabled documents, PS2EXE downloaders, LNK-based PowerShell loaders, and WinRAR archives that exploit CVE-2025-8088, to deploy custom reverse shells such as FoalShell, Chvost, Laplas, and PickleShell. Activity spans nine countries and focuses on diplomacy, economic development, environmental management, water resources, and energy. This article summarizes the campaign’s delivery methods, infrastructure exposure, indicators of compromise, and practical mitigations for defenders.
