Hi everyone, new member here but I've been learning how to use Hashcat for around a week now. Reason being I am trying to recover a project password from a Schneider TM221 PLC I use at work. The guy who used to do my job will not divulge the password.
I've found what I believe to be the hashed password in a .dll file and it appears to be SHA-256. Now, my understanding of the way the hash is produced is that the plaintext password is hashed, hashed again and XOR is involved somewhere in this process too.
Does anyone have any experience of this type of password recovery or something similar?
Presumably the way this is done will render a wordlist attack useless and brute force will be looking for standard characters when the possibility of needing to find HEX is more likely.
I would appreciate any guidance at all with this and will of course do all my own leg work if I can take some help with the method.
