The US Department of Justice has named five Russian computer hackers as members of Unit 29155 – i.e., the 161st Specialist Training Center of the Russian General Staff Main Intelligence Directorate (GRU) – which they deem resposible for the 2022 WhisperGate wiper malware attacks on Ukrainian government organizations and critical infrastructure, and subsequently computer network operations against NATO member and ally countries. “Since early 2022, the primary focus of the cyber actors appears to be targeting and disrupting efforts to provide aid to Ukraine,” states a security advisory published by the US Cybersecurity and Infrastructure Security Agency, compiled with the help of cybersecurity and government agencies of nine ally countries.
