In legacy industrial control systems (ICS), security was often designed around obscurity rather than robust cryptography. Software tools attempting to recover these passwords typically rely on a few specific vectors:
HMI backup files (.ap13, .med, .dop, etc.) stored on local hard drives or SD cards sometimes contain password hashes within their configuration databases. Crack tools parse these files to extract or clear the password field. The Dangers of Third-Party "Hot Crack" Software This public link is valid for 7 days
: Develop and enforce a password policy that requires strong passwords: a minimum length (15+ characters recommended), a mix of character types, and regular expiration. Never reuse passwords across different systems or applications.
Older PLCs and HMIs (released over a decade ago) often stored passwords in plain text or used weak cryptographic hashes. In these legacy systems, passwords could sometimes be intercepted via serial or Ethernet sniffing using traffic analysis tools, or read directly from the project file's hex data.

To eliminate the vulnerability of password cracking entirely, industrial cybersecurity frameworks (such as IEC 62443) recommend transitioning away from legacy authentication habits.

Unauthorized tools often attempt to brute-force communications or inject code into the memory sectors of a PLC or HMI. This can permanently corrupt the device firmware, bricking the hardware and requiring expensive replacements.
