Intelligence Profile

Vermin is a threat actor group linked to the Luhansk People’s Republic and believed to be acting on behalf of the Kremlin. They have targeted Ukrainian government infrastructure using malware like Spectr and legitimate tools like SyncThing for data exfiltration. Vermin has been active since at least 2018, using custom-made RATs like Vermin and open-source tools like Quasar for cyber-espionage. The group has resurfaced after periods of inactivity to conduct espionage operations against Ukraine's military and defense sectors.

Threat Analysis

UAC-0020 is a advanced-sophistication threat actor attributed to Russia, engaged in cyber operations with a primary motivation of espionage.

The group's espionage-oriented operations suggest a state-sponsored or state-aligned mandate, typically focused on stealing intellectual property, government secrets, or military intelligence. Targets are usually selected for strategic value rather than financial gain.

Classified as an advanced threat actor, UAC-0020 likely develops or acquires zero-day exploits, employs custom malware toolchains, and demonstrates long-term persistence capabilities — hallmarks of a well-resourced operation consistent with nation-state backing.
