Tools Coming To Def Con For Hacking RFID Access Doors
jfruh writes: Next month's Def Con security conference will feature, among other things, new tools that will help you hack into the RFID readers that secure doors in most office buildings. RFID cards have been built with more safeguards against cloning; these new tools will bypass that protection by simply hacking the readers themselves. ITWorld reports that Francis Brown, a partner at the computer security firm Bishop Fox, says: "...his aim is to make it easier for penetration testers to show how easy it is to clone employee badges, break into buildings and plant network backdoors—without needing an electrical engineering degree to decode the vagaries of near-field communication (NFC) and RFID systems."
>> if you're able to access the communication wiring, you probably can just reach in and grab the strike wiring too and supply 24v to it to open the door
Hammer? Check.
3x 9V batteries in series? Check.
However, it's still more work than just tailgating someone with your arms full of lunch and a laptop...
