    Thread: Bruteforce with descending characters - zzz,zzy,zzx
Post: RE: Bruteforce with descending characters - zzz,zz...

Well, my point was that if you could just start a run from the other end, you wouldn't have to calculate keyspace at all (for the case of two attack systems)

Post: RE: Bruteforce with descending characters - zzz,zz...

One use case I can think of is when you intend to bruteforce an entire keyspace, and want to "meet in the middle" by having one system work forwards, and the other system work backwards. This would wo...

Post: RE: Bruteforce with descending characters - zzz,zz...

By default, hashcat doesn't start from 'aaaaa' - instead, it starts with sets of characters that appear most frequently in common passwords, called Markov mode. For example, if you try '?d?d?d?d?d', i...

Post: RE: help with hashcat.

Are you cards detected by hashcat? What is the output of hashcat -I?

Post: RE: --markov-disable taking more time

Are you measuring the time until an actual crack is achieved, or total compute time? If you change the order of the attack, the crack will naturally happen earlier or later.

Post: RE: 3DES Known Plaintext - How?

Separate from your syntax issue ... have you done the math of how long it would take to exhaust this mask (if it were even possible to run it with hashcat)? https://www.wolframalpha.com/input/?i=95...

Post: RE: is sorting wordlist by length needed?

This is no longer necessary in modern hashcat. I've added a note to the end of that paragraph to make that explicit. Thanks for the indirect docs-bug report, always appreciated. :D

+1. You can also study which rules were effective for a given wordlist, rule list, and target hash list with --debug-mode / --debug-file.

Post: RE: help finding installed hashcat potfile

On Unix-likes, it's in a .hashcat directory in the user's home directory. Not sure if this is also true for macOS.

Take the spaces out of your mask (and note that each 'character' of the mask is '?l', not 'l?'): hashcat -m 2500 -a 3 -o password.txt dom.hccapx ?l?l?l?l?l?l?l?l

Post: RE: Can i use mask but for hash?

I think there is a fork or two of hashcat out there that does this. Also there are specialized tools like epixoip's md5substr: https://github.com/epixoip/md5substr/blob/master/md5substr.c

There are tools for doing this for some specific hash types, but official hashcat does not currently support this.
