HI There,
I am working on a CTF challenge (HTB - Bizness) and it's my first time using Hashcat.
I have found the following Hash, which I know has root pwd in it:
I know it's SHA1 w salt. The Salt is the character d. However when using hashcat with the following code it says separator unmatched:
I changed to this format as well and tried:
uP0_QaVBpDWFeo8-dRzDqRwXQ2I:d
But still returns a token length exception.
Anyone has a clue on why it doesn't work?
If it helps I know the pwd is monkeybizness and this python script can successfully find it:
