Team82 has developed a novel technique called the Evil PLC Attack in which programmable logic controllers (PLCs) are weaponized and used to compromise engineering workstations. An attacker with a foothold on an engineering workstation can have access to anything else on the OT network to which an engineer connects that machine, including other PLCs.
