In contrast, we assert that current PLC programming practices open the door to a new vulnerability class based on control-logic constructs.
The consensus from both academics and practitioners suggests stealthy process comprehension obtained from a PLC alone, to conduct targeted attacks, is impractical. Such targeted attacks typically require detailed knowledge of system-specific attributes, including hardware configurations, adopted protocols, and PLC control-logic, i.e.
Over the last decade, Programmable Logic Controllers (PLCs) have been increasingly targeted by attackers to obtain control over industrial processes that support critical services.
