RFID Hacking: Live Free or RFID Hard

Have you ever attended an RFID hacking presentation and walked away with more questions than answers? This talk will finally provide practical guidance on how RFID proximity badge systems work. We’ll cover what you’ll need to build out your own RFID physical penetration toolkit, and how to easily use an Arduino microcontroller to weaponize commercial RFID badge readers – turning them into custom, long range RFID hacking tools.

This presentation will NOT weigh you down with theoretical details, discussions of radio frequencies and modulation schemes, or talk of inductive coupling. It WILL serve as a practical guide for penetration testers to understand the attack tools and techniques available to them for stealing and using RFID proximity badge information to gain unauthorized access to buildings and other secure areas. Schematics and Arduino code will be released, and 100 lucky audience members will receive a custom PCB they can insert into almost any commercial RFID reader to steal badge info and conveniently save it to a text file on a microSD card for later use (such as badge cloning). This solution will allow you to read cards from up to 3 feet away, a significant improvement over the few centimeter range of common RFID hacking tools.
