Hackers likely working for a nation-state recently breached safety systems at a critical infrastructure facility, in a watershed attack that halted plant operations, according to cyberinvestigators and the firm whose software was targeted.
FireEye Inc. disclosed the incident on Thursday, saying it had targeted Triconex industrial safety technology from Schneider Electric SE.
Schneider confirmed that the incident had occurred, and that it had issued a security alert to users of Triconex — which cyberexperts said is widely used in the energy industry, including at nuclear facilities and oil and gas plants.
