— The MIFARE Classic, despite being introduced decades ago, remains widely deployed in access control, public transport, and campus identification systems. Its proprietary CRYPTO1 stream cipher is vulnerable to several cryptographic attacks, notably the nested authentication attack and darkside attack. This paper presents the design, implementation, and evaluation of a recovery tool that extracts the 48-bit secret keys from a MIFARE Classic 1K tag using only a standard NFC reader (e.g., ACR122U) and open-source libraries. The tool demonstrates that practical key recovery can be achieved in under 90 seconds for a fully encrypted sector.
