A security researcher is pulling a presentation of RFID security from the Black Hat Briefings following legal threats of patent infringement from a company whose proximity cards he showed to be vulnerable to attack. A planned talk on RFID security by a security researcher has been pulled from this week’s Black Hat Federal security conference after secure card maker HID Corp. claimed the talk violated the company’s patent rights and threatened to take legal action against Chris Paget, the researcher, and IOActive Inc., Paget’s employer, if the talk went forward.
