Russian military hackers linked to critical infrastructure attacks

The United States and allied agencies attribute widespread attacks on critical infrastructure and disruptive cyber operations to Russia's GRU Unit 29155 (Cadet Blizzard/Ember Bear), linking the unit to data‑wiping malware (WhisperGate, HermeticWiper), domain scanning, website defacements, data leaks, and coordinated campaigns against NATO members and other countries since 2020; the report notes indictments, a Rewards for Justice bounty for five officers and one civilian, and urges immediate hardening measures (patching, network segmentation, phishing‑resistant MFA) to defend against these destructive operations.
