GRU Unit 29155 is a Russian military intelligence unit associated with covert action, sabotage, assassination operations, and cyber activity in support of Kremlin objectives. It is widely linked to Russia’s GRU and has been publicly associated with hybrid operations against Ukraine, European states, and NATO-aligned targets. The unit is also tracked under the aliases Ember Bear and Cadet Blizzard. In cyber operations, Unit 29155 has been linked to destructive and espionage-oriented activity targeting Ukraine and other countries. Public reporting and government attributions connect the unit to the WhisperGate campaign against Ukraine and to broader operations against governments, defense organizations, think tanks, and critical infrastructure. It has also been associated with attacks against critical infrastructure in EU member states and Ukraine, and with targeting entities in NATO countries. The unit’s cyber division has reportedly collaborated with external cybercriminal and proxy ecosystems to expand capability and access. Reported activity includes working with intermediaries and cybercriminal-linked entities to recruit hackers and cyber specialists from Russian universities and academies, as well as leveraging criminal malware delivery infrastructure. Unit 29155 has also been assessed with medium-to-high to high confidence as using the SocGholish malware delivery chain to target at least one U.S. engineering firm, with follow-on delivery of RomCom tooling. This reflects overlap between Russian state operations and criminal access ecosystems. Known individuals linked to Unit 29155 include Andrey Averyanov, previously identified as a commander of the unit, and Evgeniy Bashev, who has been described as facilitating infrastructure, payments, and coordination with external hacker networks. The unit’s broader operational profile combines clandestine physical operations with cyber-enabled disruption, espionage, and support to Russian military and foreign policy goals.
