Sandworm (APT44/GRU Unit 74455) remains a premier cyber-physical threat, prioritizing ICS/OT disruption over financial gain. New analysis of 29 confirmed events (Jul 2025-Jan 2026) reveals structured operational patterns and escalatory post-detection behavior.

In brief - Sandworm’s Moscow-aligned activity targets critical infrastructure with weeks of advance warnings. Detection triggers aggressive lateral movement toward OT assets, demanding proactive hygiene and segmentation.

Technically - Sandworm leverages EternalBlue, DoublePulsar, and Log4Shell for lateral spread, averaging 43 days of precursor alerts. Post-detection, it escalates across MITRE ATT&CK tactics, increasing alert volume and ICS focus (e.g., HMIs, field controllers). Containment requires rapid vulnerability remediation and ICS-adjacent monitoring.
