Until now, getting into NFC/RFID hacking required enthusiasts to buy special hardware and learn about the underlying transfer protocols. No longer! NFCProxy is a new tool (being released at DEF CON 20) that allows you to proxy RFID transactions using Android phones. NFCProxy can record and replay RFID transactions from the perspective of the tag or the PCD (proximity coupling device). NFCProxy is an open source tool/framework that can be used to analyze 13.56?MHz RFID protocols and launch replay (and potentially man in the middle) attacks. You can even use NFCProxy as a virtual wallet by storing previously scanned RFID enabled credit cards and replaying them later at a POS (point of sale) terminal. No fancy equipment needed…just two NFC capable Android phones running ICS (one with a custom rom). Owning RFID enabled credit cards just got easier!
