CUDA Multiforcer – Multihash brute forcer

The CUDA Multiforcer is a one of the fastest multi-hash brute forcer till date! It is also the worlds fastest cross platform MD4/MD5/NTLM cracker for Windows/Mac/Linux together!

Some good features:

  • No limit on the number of hashes that can be cracked other than GPU RAM
  • Much faster on large numbers of hashes.
  • Per-position charset support (unique charset for each character position)

Sample:

CUDA-Multiforcer.exe -h NTLM -c ./charsets/charsetfull -f ./test_hash_files/hashes-ntlm-n

System requirements:

These binares require CUDA (nVidia’s API for programming GPUs to do non-graphics things). You will need the following:

  • An nVidia GPU that supports CUDA – pretty much any 8000 series or later GPU should work
  • Enough video RAM – this varies. OS X uses far more video RAM than a headless Linux server. 256MB should be enough.
  • The appropriate drivers. This is the tricky bit. You have to have recent nVidia drivers with CUDA support.
  • Compatible libraries. This should only be an issue with Linux, and any decently recent Linux should be fine. Non-standard libraries are included.
