[New Tool] Tastic RFID Thief – Proximity Badge Released

The Tastic RFID Thief is a silent, long-range RFID reader that can steal the proximity badge information from an unsuspecting employee as they physically walk near this concealed device.  Specifically, it is targeting 125KHz, low frequency RFID badge systems used for physical security, such as those used in HID Prox and Indala Prox products.


Design

They used an Arduino microcontroller to weaponize a commercial RFID badge reader (the HID MaxiProx 5375AGN00 – bought on Ebay) – effectively turning it into a custom, long-range RFID hacking tool.  This involved the creation of a small, portable PCB (designed in Fritzing) that can be inserted into almost any commercial RFID reader to steal badge info.

Note, this PCB can alternatively be inserted into an Indala reader to for testing Indala Prox deployments (e.g. Indala Long-Range Reader 620). The PCB can be inserted into any RFID reader that supports the standard Wiegand DATA0/DATA1 output (which is pretty much all of them).

The tool steals badge information silently, and conveniently saves it to a text file (CARDS.txt) on a microSD card for later use such as badge cloning.

This solution allowed us to read proximity cards from up to 3 feet away, making the stealthy approach an actual reality.  A typical attack would involve placing the weaponized reader into a messenger bag or backpack, walking by someone in line at the local Starbucks, and capturing the RFID badge info on their person.  A visualization of what the attack would look like is captured in the image below:

Note: The design was compiled and loaded onto the Arduino Nano v3.0using t Arduino v1.0.1 software with the added sdfatlib (05Dec2011) library to handle the microSD card writing. See Arduino – Libraries for more info on adding additional Arduino libraries.
