Cracking NTLMv2 Hashes With A 1080Ti Graphics Card & Kali

As far as I’m aware it’s not possible to use the power of your graphics card inside VMware Player or VitualBox. Given GPUs are so much quicker at performing that type of computing I installed Kali on a separate drive so I could optionally boot into it.

The first thing I did after install was update the system by running:

apt update && apt dist-upgrade -y && reboot

After the system has updated and restarted I ran the following:

apt install -y ocl-icd-libopencl1 nvidia-driver nvidia-cuda-toolkit

To verify it has installed correctly you can run “nvidia-smi” which will return driver version number and formation about the GPU (such as temps/utilization).

Finally if you run the command below you should be able to see if hashcat will now use your.

hashcat -I

For the full guide I followed follow this link https://docs.kali.org/general-use/install-nvidia-drivers-on-kali-linux.

Cracking NTLMv2 Hashes

I spent a while looking for wordlists to use, after running each of the word lists I managed to crack 3 out of the sample 10 hashes I had.
The command I used was:

hashcat -m 5600 hashfile.txt wordlist.txt

Next I looked at brute force and input masks, after a couple days of solid running it had cracked a further 1 password.

hashcat -m 5600 hashfile.txt -a 3

It was then while looking at a blog by someone I recently meet at SteelCon I came across a wordlist called Rocktastic that looked very promising. I downloaded it and gave it ago, instantly it cracked 7 out of the 10 hashes 🙂

More information on the Rocktastic list and a download for it can be found at Nettitude and credit for the list @myexploit2600.
