Core Werewolf

Also known asAwaken Likho · PseudoGamaredon · GamaCopy

Summary

Espionage cluster that targets Russia's defence industry, public sector and critical information infrastructure; BI.ZONE traces its first attempts to 2021. It is known for 7-Zip SFX droppers with military- and government-themed decoy PDFs and for abusing UltraVNC for remote access — tradecraft close enough to Gamaredon that Knownsec 404 named it GamaCopy (also Awaken Likho, PseudoGamaredon). In Jun–Jul 2026 BI.ZONE saw it phishing over Telegram and replacing UltraVNC with a custom C++ remote-access trojan, CoreRAT (in use since at least Mar 2026), dropped by 7zSFX and Rust droppers. One of its decoys matches a Vortex Werewolf lure; BI.ZONE says the data is insufficient to call them one actor. No state attribution.

Infrastructure patterns

  • Domains spread across many registrars — Regtime, REG.RU, GoDaddy, OnlineNIC and others (BI.ZONE, 2023)
  • Servers rented in Russia to avoid early blocklisting (BI.ZONE, 2023)
  • C2 on port 443 — UltraVNC to infovesty[.]ru, later CoreRAT to dezinsekciya-top[.]ru (BI.ZONE, 2023; BI.ZONE, 2026)
