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.

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.
