This talk covers tag-side attacks against NFC communication protocols, including cracking of Mifare encryption keys and performing targeted attacks against NFC readers. In addition, it will cover the design and creation of devices capable of emulating NFC tags down to the raw protocol using standard components and tools, with no abstraction to dedicated hardware, covering and expanding on the capabilities of available products. This talk will contain how 13.56MHz NFC works at a raw level, how tools can be built for analysing it, how the protocol can be implemented in full on standard Microcontrollers, and the security weaknesses present in its design.
