is by performing a operation, which resets the PLC to factory defaults.

Early firmware versions (V2.0, V2.1, V2.2) had a known vulnerability in the S7 communication protocol. Tools like (various developers) exploit this by sending a malformed S7 packet to read the password hash from the system memory area.

When dealing with a password-protected Siemens S7-200 SMART CPU , unauthorized extraction of the program blocks is blocked by built-in security features. To regain operational access to the hardware, you must use authorized software tools or physical hardware methods to clear the existing software and security locks.
