Black Hat: Long Range RFID Hacking
Page 1 of 1
Radio-frequency identification tags are widely deployed around the world and commonly used for building security system cards. As it turns out, those RFID security cards might not be all that secure.
That is the conclusion of Francis Brown, managing partner at security firm Bishop Fox, who detailed his research on RFID hacking on July 31 at the Black Hat security conference here. In an interview with eWEEK, Brown said he started out doing his RFID research focused on a specific requirement: He needed to break in to a building.
Although there are multiple types of RFID technologies, the focus of Brown's efforts is on the 125KHz frequency, which is the primary technology used for badge readers and physical security systems in buildings.
