MIFARE Classic Offline Cracker: given at least one known sector key it runs the nested attack to recover all remaining Crypto1 keys and dump the card, over a libnfc-driven PN532 reader. Default/transport keys are tried automatically.
Packaged in Debian, Kali and Homebrew (0.10.7); last upstream commit November 2023. It implements only the offline nested attack; mfoc-hardnested and Proxmark3 (hf mf hardnested) add the hardnested attack. Source · checked 2026-09-28
