CISA, FBI, NSA, DOE, EPA, DC3, and global partners issued a joint cybersecurity advisory urging critical infrastructure organizations to act immediately against pro-Russia hacktivist groups. The advisory warns that the groups are using low-sophistication, opportunity-driven methods to target SCADA and OT environments across water treatment, oil, energy, and other essential services. It matters because the guidance is meant to reduce the risk of disruptive attacks against systems that support critical public infrastructure.

CISA-led advisory warns critical infrastructure operators
Industry Or Public Sector UpdateCISA, FBI, NSA, DOE, EPA, DC3, and global partners issued a joint cybersecurity advisory on December 9, 2025 warning U.S. and global critical infrastructure operators about pro-Russia hacktivist groups conducting opportunistic, low-sophistication attacks against the affected organizations. The advisory says the actors exploit minimally secured, internet-facing VNC connections to access OT control devices and have targeted SCADA networks with basic methods and simultaneous DDoS attacks, and it urges organizations to reduce OT internet exposure, improve asset management, and strengthen authentication.
