proxmark3 VS ProxSpace

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).

After pulling and compiling a newer proxmark3 generic firmware from the RfidResearchGroup repo I got farther but now have a new message I've not found much about with static nonces. https://github.com/RfidResearchGroup/proxmark3/

you could use linux (ubuntu) https://github.com/RfidResearchGroup/proxmark3/blob/master/doc/md/Installation_Instructions/Linux-Installation-Instructions.md

You will have to do the leg word, but this is a starting point: https://github.com/RfidResearchGroup/proxmark3/blob/master/client/luascripts/hf_mf_sim_hid.lua

Grab yourself a Proxmark3, read the instructions here, and you can extract your iClass elite key in a few seconds. You can pick up a PM3 easy for a few bucks.

I cloned whatever the latest commit was at https://github.com/RfidResearchGroup/proxmark3, which is what the guide on dangerous things suggests (where I bought my PM).

I recommend picking up a Proxmark3 Easy. It will cost you (around $50-60)[https://www.ebay.com/sch/i.html?_from=R40&_nkw=proxmark3+easy&_sacat=0&_sop=15] depending on where you order it. Once you receive it you will need to download, compile, and install new firmware on the device. I recommend checking out (ProxSpace)[https://github.com/Gator96100/ProxSpace] which tries to automate much of this process. There are also (pre-compiled versions)[https://www.proxmarkbuilds.org/] available which make things a little easier.
