OUTAGE: Nucor Halts Production After Unauthorized Access to IT Systems

Nucor temporarily halted some production operations and took systems offline after detecting unauthorized access to its information technology environment.

The incident demonstrates how an IT compromise can interrupt manufacturing capacity and affect upstream material availability. Industrial companies should maintain tested procedures for safe production shutdown, recovery and customer allocation.

More details are available in the Reuters report.
