Support Install hashcat 6.2.3 - John1980 - 07-26-2021

I try to install it many times. But I still the error . Hashcat only run CPU , no load PGU. Please, anyone to help me to fix it.

RE: Support Install hashcat 6.2.3 - ZerBea - 07-26-2021

Your command line is faulty and the hash mode (2500) is deprecated.

Convert your dump file to new hash mode here:
https://hashcat.net/cap2hashcat/

than run hashcat in mode 22000:
$ hashcat -m 22000 xxxxx_xxxxxxxxxx.hc22000 cracked.txt.gz

where xxxxx_xxxxxxxxxx is the filename you received from the online converter (e.g.: 20702_1627284296.hc22000)
and cracked.txt.gz is a (good basic) wordlist from here (https://wpa-sec.stanev.org):
https://wpa-sec.stanev.org/dict/cracked.txt.gz

RE: Support Install hashcat 6.2.3 - John1980 - 07-26-2021

I try your command but it's no run

thanks

RE: Support Install hashcat 6.2.3 - Snoopy - 07-26-2021

you can use option
-D 2 -d 1

to tell hashcat to just use your Geforce, the combined intel CPU/GPU (device 3) and the shipped drivers are known to be "broken"

RE: Support Install hashcat 6.2.3 - ZerBea - 07-26-2021

Please comment the entire hashcat message after running:
$ hashcat -m 22000 xxxxx_xxxxxxxxxx.hc22000 cracked.txt.gz

Take also a look at your first comment and hashcat messages:
Code:
No hashes loaded.
That means there is no hash file hashcat can work on! This is the major issue.
Make sure you have a valid hash file for the chosen hash mode and a valid wordlist inside your working directory.
Or if you run mode -a 3, make sure you add a valid mask to your command line (e.g.: -a 3 ?d?d?d?d?d?d?d?d).
That is not the case in your command line!

Code:
CUDA API (CUDA 11.4)
====================
* Device #1: NVIDIA GeForce RTX 2070 Super, 7153/8192 MB, 40MCU
That means that hashcat will use your GPU running the CUDA API.

Code:
OpenCL API (OpenCL 3.0 CUDA 11.4.94) - Platform #1 [NVIDIA Corporation]
=======================================================================
* Device #2: NVIDIA GeForce RTX 2070 Super, skipped

OpenCL API (OpenCL 3.0 ) - Platform #2 [Intel(R) Corporation]
=============================================================
* Device #3: Intel(R) UHD Graphics 630, skipped
That means hashcat doesn't use the OpenCL runtime on your GPU and doesn't use
the instable Intel Runtime on the embedded Intel CPU/GPU.

Also I recommend to read the wiki to get some basic knowledge:

RE: Support Install hashcat 6.2.3 - ZerBea - 07-26-2021

Additional we can test if we get a benchmark result for your GPU:
For the new hash mode:
$ hashcat -m 22000 --benchmark

or for the deprecated hash mode:
$ hashcat -m 2500 --benchmark

Output should look like this on hash mode 22000:
Code:
$ hashcat -m 22000 --benchmark
hashcat (v6.2.3-56-gf3f6cfadb) starting in benchmark mode

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

BTW:
The commands to recover the PSK are similar on the WiFi hash modes:
on the new hash mode WPA-PBKDF2-PMKID+EAPOL:
$ hashcat -m 22000 hashfile.hc22000 wordlist

and on the deprecated hash mode WPA-EAPOL-PBKDF2:
$ hashcat -m 2500 hashfile.hccapx wordlist

as well as on the deprecated hash mode WPA-PMKID-PBKDF2:
$ hashcat -m 16800 hashfile.hc16800 wordlist

RE: Support Install hashcat 6.2.3 - Jacek - 08-25-2021

Hey buddy ZERABEA update your graphics card drivers and CUDA because your results are HIGHLY understated, I have the same graphics card as you GTX1080TI on default settings, manufacturer MSI, check in which PCX port you have the card

RE: Support Install hashcat 6.2.3 - ZerBea - 08-25-2021

Thanks for sharing your results.
My GPU is clocked down, because I'm a coder/developer (not a cracker) and I don't need full GPU speed.
In addition to that, my word lists are very small (mostly generated from hcxtools sources). That can't utilize full GPU workload, eg.:
Code:
Hardware.Mon.#1..: Temp: 74c Fan: 81% Util: 68% Core:1295MHz Mem:5005MHz Bus:16

Right now, I'm running a task (GTX1080TI) to analyze some hashes to improve hcxtools:
Session..........: hashcat
Status...........: Running
Hash.Name........: WPA-PBKDF2-PMKID+EAPOL
...
Speed.#1.........: 84540 H/s (94.49ms) @ Accel:64 Loops:256 Thr:512 Vec:1
...

Will say, no need for me to take care about "best" hashcat benchmark results.
