HashCat does not running correctly

[marek.kovalcik]

Hello,
I have a problem with cracking WPA2 password with HashCat. I have captured handshakes in handshake04.hccapx . I am using crunch with custom charset and john the ripper tool as well.

Command: crunch 8 14 -f Charset\charset.lst bdo | john –stdin –session=BDO_WIFI –stdout | hashcat -m 2500 -d 1 Jobs\BDO_firemni_wifi\handshake04.hccapx
Charset: bdo = [abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%&*()-_+=[]{}\:;”‘,.?/]

I am using GeForce RTX 2080 Ti: https://freeimage.host/i/2mfrkx
I installed CUDA toolkit 11.1

Running crunch+john+hashcat: https://freeimage.host/i/2.2mfZEF

1) Why the status is Exhausted?
2) Why the progress is not changing?
3) When I open tak manager, I can see that processor is working o 25% and GPU is working on 0%. Why is it calculating on CPU and not GPU?

Thank you!

If you look closely at the output in your second screenshot you can see that john prints an error and stops. I have no idea why you are using crunch and john at all. Just use a hashcat mask attack.

just to make it clear what error undeath is referring to:

Code:

fopen: john.conf: No such file or directory

This is what JTR (John The Ripper) is printing as an error messages and it exits afterwards.

I agree with undeath that this is not a hashcat problem. You also do not need JTR, nor crunch for this type as attack (again, as undeath already told you, use a mask attack instead: https://hashcat.net/wiki/doku.php?id=mask_attack

Thanks for your answers. I have another problem. I cannot see usage of GPU in my windows task manager. I can see that the temperature of GPU is increasing (so I guess it is working) but i can see 0% usage in windows task manager. Do you know why?

[philsmd]

it's not where you should look for GPU usage.

use hashcat built-in "Util' percentage in the status prompt or some tuning software instead (GPU-Z, afterburner etc).

The windows task manager doesn't show the actual usage of the devices... it just shows some numbers for known applications (media players, video editing tools etc).

Change charset list, hashcat don`t like symbols in mask attack by my experience

[philsmd]

that's of course not true and must be an user error/problem
