Word Mangling/Wordlist generator - Hash_noob - 01-13-2018

Hi There,

I'm trying to crack a lost password. I think I know what it is, but must have originally entered it incorrectly as it is not working. Is there a way in Hashcat to enter the password and have Hashcat mangle each letter, misspelling it. 

I have tried to generate a wordlist of misspelled words but Crunch doesn't seem to work for windows 10. If this is not possible in hashcat can you recommend a wordlist generator that can do this in windows

I'd appreciate your help.

That's what rules do.

RE: Word Mangling/Wordlist generator - royce - 01-13-2018

Yeah, what undeath said - if we're talking about typos, or misspellings that are just a single character substitution, some rules are pretty good at transposing letters. Specifically, a ruleset like this:

Code:
$ cat typo-swap.rule *01 *12 *23 *34 *45 *56 *67 *78

... would do this:

Code:
$ echo hashcats | hashcat -r typo-swap.rule --stdout ahshcats hsahcats hahscats haschats hashacts hashctas hashcast hashcats

And rules like this for character substitutions:

Code:
$ cat typo-wrong.rule saq saw sas sax saz $ echo hashcat | hashcat -r typo-wrong.rule --stdout hqshcqt hwshcwt hsshcst hxshcxt hzshczt

If it's a fast hash and you're feeling lazy, you can just throw all of the possible characters into a custom character set (-1, -2, -3, -4 syntax).

Code:
$ hashcat -m 0 -a 3 -1 'hasct' --stdout ?1?1?1?1?1?1?1 | head sattasa chatasa ashaasa tattasa hattasa shatasa cattasa aattasa thatasa hhatasa $ hashcat -m 0 -a 3 -1 'hasct' --stdout ?1?1?1?1?1?1?1 | wc -l 78125 $ hashcat -m 0 -a 3 -1 'cat' --stdout hash?1?1?1 hashata hashtat hashcat hashaca hashtta hashcca hashaat hashtca hashcta hashatt hashtac hashcac hashact hashttt hashcct hashaac hashtct hashctt hashatc hashtaa hashcaa hashacc hashttc hashccc hashaaa hashtcc hashctc

Adjust the hard-coded characters in the mask with the wildcard ones (?1) to taste.

If the rules syntax is tricky for you, and if it's a slow hash, you might be be better off scripting something that does the mangling for you, or using a different external tool. Googling for "typo generator" has some interesting hits.

Thanks for your responses. Yes I thought this might be based around rules. Just wasn't sure how to construct them to do what I wanted so thank you for your help.

Unfortunately its a slow hash (old litecoin wallet, you're probably sick of these) and a phrase. So it might be more efficient to construct a wordlist of typos instead of having hashcat try to mangle in real time. I'll look into Typo generators.

Thanks again.

RE: Word Mangling/Wordlist generator - royce - 01-13-2018

Good luck!

And for what it's worth, here are some nuggets for how to use kwprocessor (keyboard walk processor) and hashcat rules + stdout to generate a wordlist of typos. It's not an ideal approach, but might work for some use cases.
