history

Project history and usage

MFOC, the Mifare Classic Offline Cracker, is an open-source implementation of Nethemba's offline nested attack against MIFARE Classic cards. The nfc-tools README states that it recovers authentication keys from MIFARE Classic cards when a default or user-supplied key is known. The AUTHORS file names the Nethemba Core Team, with Norbert Szetei as main coder and Pavol Luptak as project leader, minor coder, tester, and bug reporter.

Project history

The project traces back to Nethemba's 2009 public release of an offline nested attack implementation for Mac OS X and Linux. The nfc-tools changelog records the import of MFOC 0.08 from nethemba.com into the nfc-tools repository on September 13, 2010, followed by maintenance work to track libnfc APIs, add packaging, add a manpage, support newer MIFARE Classic UID cases, and clean up the C code through 2013.

How it is used

MFOC's practical role is narrower than broad NFC libraries: it is a command-line recovery and audit tool for MIFARE Classic deployments, generally used with libnfc-supported readers and known-key attack workflows. In package managers it commonly appears beside MFCUK and libnfc as part of the NFC/RFID security-research toolkit, with MFCUK covering the DarkSide-oriented path and MFOC covering the offline nested attack path.
