Get your hands dirty playing with RFID/NFC

You will enjoy playing with RFID/NFC+ devices. SCL3711, ACR122U, Proxmark3, HydraNFC and more. During both days you will deal with different types of the most common transponders that can be found in the wild (aka tags, tokens, etc.). More tinkering, hacking and hands-on than ever, starting right away from the first day. No tons of theory. You can read the papers later, right?

The workshop covers RFID from the Low Frequency band (mainly used for individual physical access to buildings, garages, hotels, etc.) to the High Frequency band, where credit cards, passports, but also NFC come into play. We will provide you with all the tools, materials and references for further study and research, with a strong emphasis on free software & free hardware.

You will understand which type of access cards can be emulated or even cloned; then we are going to use traditional NFC USB readers, we will compile and execute the famous LibNFC, and play with some special hardware like the Proxmark3 and HydraNFC. Arduino examples will be shown to deal with both Low and High frequency cards and tokens. You will learn how to deal with the most common LF and HF transponders.

HID iClass vulnerabilities will be discussed as well as the NXP MIFARE Classic (and Plus) technology along with its public hacks.

We will discuss some case studies, practical hacks and lessons learned from working systems the can be found in the wild, including ePassports, RFID Toys, Credit Cards and Host-based Card Emulation. Also, a Proxmark3 board will be provided to each attendee to keep. There is no additional charge for this item, but if you would like, you can feel free to make a donation to the TROOPERS’ Charity!

Requirements

• No prior RFID / NFC technology knowledge is required. We will start from the very beginning. Any RFID / NFC transponder or device is very welcome to share experiences and try some hacks on/with them.

• Laptops with preferably a linux setup (natively or in a VM, e.g. a Kali) and a compilation environment (git, gcc and gcc-arm <5) to play with the equipment

• It is desirable to have a minimum knowledge of C language – debugging, compiling, and running. You may succeed using other OSes but you’re on your own…
