Real RFID Hacking Scenarios

Posted by ryuzaki0 on from the rfid-underground dept.

kjh1 writes "Wired is running an article on RFID hacking that has potentially scary implications. Many RFID tags have no encryption and will happily transmit their information in the clear if they are active or within range of a reader. Worse yet is that they can be overwritten. Some interesting scenarios and experiments: snagging the code off of a security badge and replaying it to gain access to a secure building; vandalizing library contents by wiping or changing tags on books; changing the prices of items in a grocery or other store; and getting free gas by tweaking the ExxonMobil SpeedPass tags."

  1. Regarding security badges by benjjj · · Score: 5, Informative

    I think it's common practice for most serious security badges to rely on RFID for part of the verification, but some sort of user input for the rest. I have a prox card at work (which, I assume, is an RFID-based card), but the card only activates a keypad. Without my PIN, it's useless.
