Recent research by ESET has uncovered evidence of unprecedented collaboration between two Russian state-linked cyberespionage groups: Gamaredon and Turla. Their cooperation in targeting high-profile organizations in Ukraine represents a significant escalation in state-sponsored hacking, with implications for global cybersecurity. Known for its high-volume, opportunistic campaigns, Gamaredon often relies on spear-phishing and malicious LNK files on removable drives to gain access. While Gamaredon compromises hundreds or thousands of Ukrainian machines, Turla appears to focus on a small subset of systems likely containing highly sensitive intelligence. The discovery of cooperation between Gamaredon and Turla marks a new phase in Russian cyber strategy.
