Overview
Ember Bear is a Russian state-sponsored cyber espionage group that has been active since at least 2020, linked to Russia's General Staff Main Intelligence Directorate (GRU) 161st Specialist Training Center (Unit 29155).(Citation: CISA GRU29155 2024) Ember Bear has primarily focused operations against Ukrainian government and telecommunication entities, but has also operated against critical infrastructure entities in Europe and the Americas.(Citation: Cadet Blizzard emerges as novel threat actor) Ember Bear conducted the WhisperGate destructive wiper attacks against Ukraine in early 2022.(Citation: CrowdStrike Ember Bear Profile March 2022)(Citation: Mandiant UNC2589 March 2022)(Citation: CISA GRU29155 2024) There is some confusion as to whether Ember Bear overlaps with another Russian-linked entity referred to as Saint Bear. At present available evidence strongly suggests these are distinct activities with different behavioral profiles.(Citation: Cadet Blizzard emerges as novel threat actor)(Citation: Palo Alto Unit 42 OutSteel SaintBot February 2022 )
