Siemens S7 controllers utilize a hierarchical protection concept to prevent unauthorized modification or theft of the control logic. When a user sets a password on an S7-300 or S7-400 CPU, they are defining access rights across four levels.
PLCs. Siemens has improved security in these lines by using hashed passwords and hardcoded cryptographic keys, making simple "finding" tools obsolete. User Consensus : Reviewers on community forums like hashcat -m 15100 -a 3 extracted_hash
