Vulnerabilities in Rockwell Automation PLCs Could Enable Stuxnet-Like Attacks

A security vendor’s recent analysis of Rockwell Automation’s programmable logic controller (PLC) platform has uncovered two serious vulnerabilities that give attackers a way to modify automation processes and potentially disrupt industrial operations, cause physical damage to factories, or take other malicious actions. Researchers from Claroty Team82 discovered the vulnerabilities and this week described them as being Stuxnet-like in nature because of how they allow attackers to run malicious code on a PLC without triggering any obviously unusual behavior.
