Gamaredon 2025 zero-click RAR to Pteranodon and rotating C2 infrastructure
UAC-0010
IIM chain for the November 2025 Gamaredon zero-click delivery path: a Ukraine-themed RAR archive abuses CVE-2025-6218/CVE-2025-8088 style archive delivery to place an HTA in the Windows Startup folder. The HTA/loader reaches DynDNS-backed delivery infrastructure, retrieves/launches Pteranodon, and then uses Telegram/graph.org dead-drop resolver infrastructure plus DynDNS/Fast-Flux C2 nodes for tasking and payload rotation.
