Attackers are starting to target the critical infrastructure that runs industrial and manufacturing facilities. That may not sound like a new thing but the speed and sophistication with which they're increasing their attacks is. Security firm Dragos hast noted in a recent post that there has been a significant increase in the number of people using password cracking tools on industrial equipment such as programmable logic controllers (PLCs). Where the real devilish genius comes into play is not tha these attackers are trying to corrupt them. Instead, they're converting these machines into nodes in large botnets to amplify attacks. And if you think it's hard to clean a malware infection from a PC try doing it on a PLC that can't be shut down. Dragos noted that while they only tested one particular kind of PLC many other samples had traces of malware infections. Stephen, is this going to cause issues for our already strained supply chain?
