Towards Obfuscation of Programmable Logic Controllers
Vittoria Cozza, Mila Dalla Preda, Marco Lucchese, Massimo Merro, Nicola Zannone · 2023
Recently published scan data on Shodan shows how 105K Industrial Control Systems (ICSs) around the world are directly accessible from the Internet. In particular, highly sensitive components, such as Programmable Logic Controllers (PLCs), are potentially accessible to attackers who can implement several kinds of attacks. On the other hand, to accomplish non-trivial cyber-physical attacks the attacker must possess a sufficient degree of process comprehension on the physical processes within the target ICS.
