Post: RE: Mask Attack with a "blank" value?
| In general you do this mangling (like appending/prepending characters etc) with rule based attacks (with -a 0 and -r my.rule for instance), i.e. you run a wordlist and add those special characters and... |

Code:

Thread: Mask Attack with a "blank" value?
Post: RE: Mask Attack with a "blank" value?
| This type of attack makes no sense to me. You are basically just trying some combinations of the characters "0", "5", "7", "!" and "@" (together with --increment right?).
