  Iceman Fork - Proxmark3

  

Project mention: Flipper Zero: Multi-Tool Device for Geeks | news.ycombinator.com | 2024-01-21

I would check out the Proxmark3 Github repo [0]. They have a cheatsheet [1] with the basics on how to get started. I also did a talk about RFID security last year about the basics [2]

To get started, the basics are: low freq (LF) is usually around 125khz and is rarely encrypted (HID Prox is the most common in the US). The data is often encoded in Wiegand format for access control systems (something to keep in mind when reading the raw data).

High freq (HF) (aka NFC) is ~13Mhz and is readable by most Android phones with NFC. Not all tag data can be read however. HF cards support a lot of different options including data storage (normally in a block layout with permissions to read and write depending on keys) and encryption (iCLASS and SEOS being the HID offerings and very common). Some can be cloned (like hotel cards) while others (like SEOS) require a downgrade attack to work correctly (SEOS -> normal SEOS reader -> Weigand data -> older style card like HID Prox).
