Dangerous ICS Malware Targets Orgs in Russia and Ukraine

The report describes two ICS/OT-focused malware: Kapeka, a Sandworm-linked backdoor used for early-stage access, persistence, and remote operations, and Fuxnet, a destructive Blackjack-linked tool that overwrites gateway NAND and floods sensors with M‑Bus traffic — reportedly bricking ~1,700 gateways and disabling ~87,000 sensors; the incidents illustrate nation-state-linked, high-impact attacks on critical infrastructure and emphasize basic mitigations like strong credentials, network segmentation, and device management.
