RFID Exploration Workshop

Event Start: 10 Monate, 1 Woche her // Event Information

RFID-like technologies are becoming pervasive, but traditionally have not been very open or experimenter-friendly. In the past few years, a growing variety of hardware and software tools have been enabling open-source experimenters to interact with contactless devices in a new way. In this workshop, we: - Show some common tag types and demonstrate ways of identifying them - Describe the very cheap/common Mifare Classic chip type and protocol - Crack the secret keys inside a Mifare Classic card, and clone the content onto a copied card - Have a cute, beepy badge reader to test cloned tags with; lights and sound will show you if your clone worked Participants will: - Learn some RFID basics, learn some UART (Serial Port) basics - (With the PN532 boards) Solder on through-hole header pins - Download and run open source software to control the hardware (works best on Linux; best-effort support for MacOS and Windows/WSL) - Crack the "secret" unknown keys of a provided card, dumping it to a file - Write the dump file to a new card, effectively cloning the original card No novel research or new information will be presented -- this workshop is aimed at empowering more people to interact and experiment with the devices that surround us. Seasoned RFID hackers are welcome to join in and hang out.

For the hardware used to connect computers with contactless devices, there are two types of kits available for participants to buy: - (~35 available; sliding scale €5,-€10,) USB-UART Board + NXP PN532 board (HF tag types) - (~2 available; sliding scale €30,-€50,) Proxmark3 Easy (HF + LF tag types) - (~20) Mifare Classic 1k Cards with the "secret" keys inside - (many/~100; €0,50) "Magic" Mifare Classic 1k Cards that can change their "unique" ID

Participants should bring: - A computer: - running Linux (or able to run a Linux VM and pass through a USB Device) - with USB type A connectors - any RFID devices or cards you are curious about

To borrow or experiment with during the workshop (but need to be returned at the end): - USB HF readers - Chameleon Mini - Chameleon Tiny
