Problems with speed of brute-force by GPU - PilyaPlay - 03-01-2018
Hello every one , can somebody help me with this problem ?
The problem is that Hashcat 4.1.0. worked with low performance .
I write code like that ↓ to try brute my own AP and hashcat show me Speed.Dev.#1 25 H/s
Code:
hashcat64.exe -a 3 -m 2500 -w 4 E:\wi-fi24.hccapx E:\Top204Thousand-WPA-probable-v2.txtBut , i have run Benchmark and he show me 62330 H/s .
I saw thah he write ↓ but when i give him larger wordlist (250MB) , it have "freeze" on it.
Code:
The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.
For tips on supplying more work, see: https://hashcat.net/faq/morework
Approaching final keyspace - workload adjusted.Does anybody hawe any solutions ?
Thank you in advance!
P.S. Hardware - i5 6300HQ , GTX 960m ( driver 391.01)

Show your status output. You're probably trying to crack more than one digest, thus dividing your hashrate.
Quick edit: Or because it's a laptop your overheating and it's causing your GPU to throttle is more or less probably what it is.

Please click on " 25 H/s " in my text , it's link on Google Drive ( screenshot)
On screenshot i see the same digest as yours.

Quick edit: Just right now launched Assassin`s Creed. Origins ( Ultra , 1080p ) , Stable gameplay ( 30-40 FPS ) temperature 67c , no throttle or overheating.
And the stable load Gpu (99%) is not similar to the hashcat ( he have some "falls") graphics.

Firstly being able to play a game doesn't really matter.
Secondly, try using -a 0 instead of -a 3. You are using the wrong attack mode for wordlists

Your status is "Exhausted", HAshcat seems to be finished. Runniung time 0s. There is definitly something but it's not the speed of your GPU. Try TofuBoys tip for starters.

It was about throttle/ overheating ( long time playing in the game very nice test to heat the GPU)

Finaly i have my 62 kH/s ( My try was faild because it was 3 in instruction and i was thinking that it was a Brute-force (but it's not right) . I was thinking that brute-force is getting examples of passwords from wordlist and try to find correct password . And now i don't understand how to use brute-force if password wouldn't be in wordlist. Can you give me a link on instruction "How to use Brute-force" with details ?)
