The company decided to cancel the talk after all-night negotiations with HID collapsed, said Josh Pennell, CEO of IOActive. In response, Black Hat organizers were forced to tear materials out of printed show proceedings and will instead present a discussion by a representative of the ACLU on the criticality of RFID security, said Jeff Moss, founder and director of Black Hat.

Paget's RFID cloning device was , where he how the device could be used to steal access codes from HID brand proximity cards, store them, then use the stolen codes to fool a HID card reader.

Paget's presentation at Black Hat Federal would have included'schematics and source code that attendees could use to create their own cloning device, and a discussion of vulnerable implementations of RFID technology in a wide variety of devices, Paget told InfoWorld at RSA earlier this month.
