cudadbcracker: CUDA Database Cracking Tool

cudadbcracker - CUDA Database Cracking Tool



We start this new decade with cudadbcracker a cracking tool that uses our CUDA capable GPUs to crack Microsoft SQL and Oracle databases password hashes.


cudadbcracker is a salted SHA-1 cracker for cracking database password hashes using CUDA enabled video cards. cudadbcracker was developed using NVIDIA CUDA Software Development Kit (CUDA SDK) 2.1 and is a free software that currently supports MSSQL and Oracle 11g hashes.


I did a quick test with an EVGA GeForce GTX295 (Forceware 195.62 – Vista 32-bit sp2) on the Oracle passwords file (running ora11g_test.cmd). cudadbcracker cracked all passwords (47) in 202 seconds at a speed of about 200 millions passwords / second.

I wasn’t able to see the GPU usage (MSI Afterburner failed to startdue to missing components…) so I used GPU-Z but switching between one GPU to the other with the combo box was rather hard. I tried with SLI enabled and disabled to see if there was a difference in speed (when SLI is disabled, a CUDA application can use both GPUs of a GTX 295) but the cracking speed was always 200 M passwords / sec. Currently the tool seems to use only one GPU.

Power consumption (total system power):
- Idle: 130W
- cudadbcracker: 240W
- FurMark: 280W

Like this other GPU based cracking tool, don’t try to do other tasks during the test because the GPU is very busy and can’t handle correctly your actions.
