DHS, FBI Warn Companies of Ongoing Cyber Attacks on Critical Infrastructure

The Department of Homeland Security and FBI issued rare public alert warning owners of U.S. critical infrastructure to battle an ongoing campaign of cyber attacks against their information and control networks.

Energy and industrial firms were notified Friday and again Saturday that sophisticated hackers are attempting to penetrate industrial control systems used by the electrical and nuclear power industry, as well as water, aviation, and manufacturing sectors.

"DHS assesses this activity as a multi-stage intrusion campaign by threat actors targeting low security and small networks to gain access and move laterally to networks of major, high value asset owners within the energy sector," the notice said.
