The aim of this project is to develop a GSM sniffer and tools for key recovery.

Project highlights: OpenCL A5/1 cracker and statistical keystream guesser capable of cracking the key in several seconds and 99% probability on an insecure network and in several minutes on a secure network with ~30% probability.

Project status:

Missing parts:

  • UI that won't require excessive shell magic.
  • SDR-based sniffer capable of recording adjacent channels and decoding phonecalls after the key is cracked.
  • Statistical guesser using SI5/5ter/6 messages less stupidly than “we pipe them to the cracker and hope some will be solved”.
