A researcher has rigged a programmable logic controller with a low-cost hacking tool that can shut down a process control network with a text message. The so-called PLCpwn prototype took Digital Bond researcher Stephen Hilt less than two weeks and about $400 to build. “You know how it goes once you learn from Stuxnet,” says Ralph Langner, founder of Langner Communications. Idaho National Laboratory is working on algorithms and coding tricks to miniaturize attack code so it can hide on small embedded CPU.”]
