Feds At DefCon Alarmed After RFIDs Scanned

FourthAge writes "Federal agents at the Defcon 17 conference were shocked to discover that they had been caught in the sights of an RFID reader connected to a web camera. The reader sniffed data from RFID-enabled ID cards and other documents carried by attendees in pockets and backpacks. The 'security enhancing' RFID chips are now found in passports, official documents and ID cards. 'For $30 to $50, the common, average person can put [a portable RFID-reading kit] together,' said security expert Brian Marcus, one of the people behind the RFID webcam project. 'This is why we're so adamant about making people aware this is very dangerous.'"

      This is a legal gray area, but a couple years back Wired suggested that hitting the passport's chip with a hammer would disable the RFID without obvious signs--a disabled RFID chip does not invalidate the passport.

      I found this part really interesting:

      It's not known if any Feds were caught by the reader. The group that set it up never looked closely at the captured data before it was destroyed. Priest told Threat Level that one person caught by the camera resembled a Fed he knew, but he couldn't positively identify him.

      "But it was enough for me to be concerned," he said. "There were people here who were not supposed to be identified for what they were doing ... I was [concerned] that people who didn't want to be photographed were photographed."

      Priest asked Adam Laurie, one of the researchers behind the project, to "please do the right thing," and Laurie removed the SD card that stored the data and smashed it. Laurie, who is known as "Major Malfunction" in the hacker community, then briefed some of the Feds on the capabilities of the RFID reader and what it collected.

      Nice to see that - after they made their point - the organizers and attendees at "one of the most hostile hacker environments in the country" did the right thing and destroyed the data. I'm sure we could count on law enforcement, our employers and credit card companies to show the same moral character.

My friend's dad works in and out of Boston in some pretty rough neighborhoods, and after witnessing a crime and calling the police he had several DOCUMENTED threats made against his life (ie coming out to see WE ARE GOING TO F*CKING KILL YOU HONKY spraypainted on the side of his truck). Even with this, he was not able to obtain a concealed carry permit. His criminal record is 100% clean, and he even knew some guys high up in the force that could pull some strings, but eventually the reason he got was that they didn't see that he needed to carry a gun.

I was traveling again shortly after and tried to find someone who could tell me if it was still valid, but had no luck. I was going from the U.S. to Mexico and just figured I'd see how it went.

      The agent tried to scan the chip and when it didn't work, just treated it like an older passport. I've gone out of the country with it again since then and had the same result.

      I wouldn't recommend that approach, as is mentioned above, a hammer will do the job. It took me a while to dry out my passport then I had to leave it under a huge stack of books to get the pages flat again. Knowing that people keep them for 10 years makes me think that they must go through all kinds of things like that.

      The nano took longer to dry out completely but still works.
