Altough this check is empirically verified and it works with the images of this repo encrypted with Windows 7, 8.1 and 10, we can't guarantee that it doesn't lead to false negatives. build/bitcracker_cuda -f -d Options: -h, -help Show this help -f, -hashfile Path to your input hash file (HashExtractor output) -s, -strict Strict check (use only in case of false positives) -d, -dictionary Path to dictionary or alphabet file -g, -gpu GPU device number -t, -passthread Set the number of password per thread threads -b, -blocks Set the number of blocks Note: In case of false positives you can use the -s option, that is a more restrictive check on the correctness of the final result.

Then you can use the output hash file to run the BitCracker attack. build/bitcracker_hash -i -o Options: -h, -help Show this help -i, -image Path of memory unit encrypted with BitLocker -o, -outfile Output file The extracted hash is fully compatible with the John The Ripper format (see next Section). Before starting the attack, you need to run bitcracker_hash to extract the hash from the encrypted memory unit. The executables are stored in the build directory. Kepler arch) How To Use the build.sh script to build 3 executables: Requirements For CUDA implementation, you need at least CUDA 7.5 and an NVIDIA GPU with minimum cc3.5 (i.e.

Here we present two implementations: CUDA and OpenCL. Our attack has been tested on several memory units encrypted with BitLocker running on Windows 7, Window 8.1 and Windows 10 (both compatible and non-compatible mode).
