MCT 2.3.1 operates through the Android OS’s NFC stack, interfacing directly with ISO/IEC 14443 Type A tags. Unlike its predecessors, version 2.3.1 incorporates refined error handling and extended key diversification algorithms. The software’s core capabilities are threefold: (enumerating sectors and blocks on a card), reading (extracting encrypted data from sectors when a valid key is provided), and writing (cloning data to UID-writable tags). A significant addition in this version is the integrated nested authentication attack . This exploit leverages the linear feedback shift register (LFSR) vulnerability in the CRYPTO1 cipher. By capturing a successful authentication with one known key, MCT 2.3.1 can reverse-engineer other sector keys of the same card within seconds, a process that would take weeks using brute force on legacy hardware.
