Hashcat Bruteforce Mode failure - Kangaroot - 01-30-2018

Seems like Hashcat Brute force mode stopped properly working. Nothing was changed in terms proprietary nvidia drivers, though I have updated linux kernel several times, not sure when exactly it started to behave like this.

Example: hashcat -m 2500 -a 3 -w 3 [path-to-hccapx-file] ?a?a?a?a?a

Return: Skipping mask '?a?a?a?a?a' because it is smaller than the minimum password length.

After that hashcat stops. I've tried any number of chars, it returns the same apart from when I go over 9 chars. Used to work with any number of chars. What I'm missing out here?

wpa passwords must have a length of at least 8 characters. If it worked before that was a bug.

undeath, it would have made sense if I didn't have old router with old firmware, where I could simply change my pass to whatever I liked.


RE: Hashcat Bruteforce Mode failure - undeath - 01-30-2018

the wpa specification does not allow passwords shorter than 8 characters.


RE: Hashcat Bruteforce Mode failure - Kangaroot - 01-30-2018

undeath, is it not just a recommendation?


RE: Hashcat Bruteforce Mode failure - undeath - 01-30-2018

it is not.


RE: Hashcat Bruteforce Mode failure - Kangaroot - 01-30-2018

undeath, thank you for support! May I ask for some references in protocol where this is being determined?

Skwerl23, great, thanks. Missed this paragraph when read it first time.
