Siemens has issued a patch for its SIMATIC S7-300 and S7-400 families of programmable logic controllers (PLCs)—industrial control systems used to remotely monitor and operate manufacturing equipment. This is in response to a year-old product vulnerability warning originally issued in December of 2016 and recently updated to include another version of the S7-400 line. The controllers were vulnerable to remote attacks that could allow cybercriminals to obtain login credentials to the system or reset it into a “defect” mode, shutting down the controller.
