US govt warns of pro-Russian hacktivists targeting water facilities

Multiple U.S. and allied cybersecurity agencies warn that pro‑Russian hacktivists have been targeting insecure operational technology (OT) systems—primarily by abusing VNC to access human‑machine interfaces (HMIs)—causing nuisance effects and some tangible disruption to water infrastructure; the advisory links some activity to Sandworm/APT44, documents a confirmed overflow incident, and recommends hardening OT (firewalls, MFA, patching, changing defaults) to reduce risk.
