Crowdstrike says Ember Bear is likely responsible for the wiper attack against Ukrainian networks and that future Russian cyberattacks might target the West.
As fears mount over the prospects of a “cyberwar” initiated by the Russian government, the number of identified Russian threat actors also continues to climb. Last week CrowdStrike publicly revealed a Russia-nexus state-sponsored actor that it tracks as Ember Bear.
CrowdStrike says that Ember Bear (also known as UAC-0056, Lorec53, Lorec Bear, Bleeding Bear, Saint Bear) is likely an intelligence-gathering adversary group that has operated against government and military organizations in eastern Europe since early 2021. The group seems “motivated to weaponize the access and data obtained during their intrusions to support information operations (IO) aimed at creating public mistrust in targeted institutions and degrading government ability to counter Russian cyber operations,” according to CrowdStrike intelligence.
Ember Bear is responsible for using the WhisperGate wiper malware against Ukrainian networks in January before Russia invaded Ukraine. The malware masquerades as ransomware but lacks a payment or data recovery mechanism, masking WhisperGate’s true intent, which is the destruction of data. The WhisperGate campaigns began with website defacements containing threatening messages in Ukrainian, Russian and Polish languages.
