Workstation software flaw exposes industrial control systems to hacking

The software used to program and deploy code to various Schneider Electric industrial controllers has a weakness that could allow hackers to remotely take over engineering workstations.The software, known as Unity Pro, runs on PCs used by engineers and includes a simulator for testing code before deploying it to programmable logic controllers (PLCs). These are the specialized hardware devices that monitor and control mechanical processes -- spinning motors, opening and closing valves, etc. -- in
