Four fixes, three of them from auditing the simulation against M134034 rather than from a failing test, and one found by the audit's own new test. An error status now ends the authenticated session. "The CMAC is not calculated and attached, if an error code is returned. Then the application of the PICC leaves the authenticated state and needs to be authenticated again" (7.3.4). The simulation had 127 error returns and eight of them cleared the session, so a reader saw an authenticated session survive errors no real card survives. It is applied once where a command's answer leaves the dispatcher, rather than at every error return, so a new error path cannot forget it. 0x00, 0x0C, 0x90 and 0xAF are the four statuses that are not errors. Answers are sized from the reader's frame size. The reader states it in its RATS -- FSDI in the high nibble of the parameter byte -- and the simulation ignored it in favour of a fixed 96 byte chunk. That is safe against a reader asking for 256 and wrong against anything below 128, which would be sent frames it cannot receive. The chunk now comes from FSDI, rounded to a whole cipher block. A reader asking for less than 32 bytes still cannot be served, because the status byte, a CMAC and the framing cost twelve before any payload, but nothing in practice asks for that and this card's own ATS advertises 64. The length of a write is taken from the command instead of guessed. WriteData, WriteRecord and UpdateRecord each carry a 3 byte length in their header, and the header is in the clear in every communication mode, enciphered included, so the total is known from the first frame. The simulation had been treating "this frame looked full" as "more is coming", which is guesswork about something the protocol states outright. Writing that test found that a chained write never worked at all. The dispatcher refused an 0xAF continuation unless a read was being chained or an authentication was half done, so the second frame of any write longer than one frame came back 91 1C. Every write tested until now fitted a single frame. It is one more condition on that check. Tested against the simulation: 100 byte writes in plain, MACed and enciphered mode all complete over two frames and read back byte for byte, `hf mfdes dump` walks three applications and six files with no errors, and the regression harness passes.

Iceman Fork - Proxmark
The Proxmark is the swiss-army tool of RFID, allowing for interactions with the vast majority of RFID tags on a global scale. Originally built by Jonathan Westhues, the device is now the goto tool for RFID Analysis for the enthusiast.
Iceman repository is considered to be the pinnacle of features and functionality, enabling a huge range of extremely useful and convenient commands and Python/LUA scripts to automate chip identification, penetration testing, and programming.

How to build?
Proxmark5
The last hardware generation is called Proxmark5. It has
- MCU: AT32F435, a 288 MHz Artery Cortex-M4
- Gowin FPGA
- TypeC Extended Port (CEP)
- BLE / Wifi / Battery Addon, via a ESp32c2
- Swappable antennas (LF, HF, UHF)
- 125, 134, 250, 375, 500 KHz Low Frequency Antenna (LF)
- 13.56 MHz High Frequency Antenna (HF)
- as a addon: 860-960 MHz Ultra High Frequency Antenna (UHF), ** not developed yet **
At the moment, Proxmark5-specific instructions are all grouped in a single Getting Started guide. Read it to build, flash and run your Proxmark5 device. See the instruction links in the tables above to get the compilation environment.
- ⚠ The firmware is not stable at the moment and is actively being developed at.
- ⚠ Don't install the BWM addon board for now.
Proxmark3 RDV4
See the instruction links in the tables above to build, flash and run for your Proxmark3 RDV4 device.
Generic Proxmark3 platforms
In order to build this repo for generic Proxmark3 platforms we urge you to read Advanced compilation parameters
We define generic Proxmark3 platforms as following devices.
Supported
- RDV1, RDV2, RDV3 easy
- Ryscorp green PCB version
- Radiowar black PCB version
- numerous Chinese adapted versions of the RDV3 easy (kkmoon, PiSwords etc)
- Proxmark3 SE (Special Edition) (BLE enabled)
- Proxmark3 X
- Note: Community tested
- Note: unknown device hw
- iCopy-X
- Note: Compatible ONLY after installation of iCopy-X Open Source firmware
- Factory firmware is not compatible (Client Commands are different / Factory UI closed source / Factory Firmware enforces tag DRM)
Not supported
- ⚠ Proxmark Evolution (EVO)
- Note: unknown pin assignments.
- ⚠ Ryscorp Proxmark3 Pro
- Note: device has different fpga and unknown pin assignments.
- Note: Company have disappeared, leaving their customers in the dark.
Experimental support
- ⚠ Proxmark3 Ultimate
- Note: unknown device hw
- Note: FPGA images is building for it. Use on your own risk.
Unknown support status
- ⚠ VX
- Note: unknown device hw
When it comes to these new unknown models we are depending on the community to report in if this repo works and what they did to make it work.
256KB flash memory size of generic Proxmark3 platforms
⚠ Note: You need to keep a eye on how large your ARM chip built-in flash memory is. With 512KB you are fine but if its 256KB you need to compile this repo with even less functionality. When running the
./pm3-flash-allyou can see which size your device have if you have the bootloader from this repo installed. Otherwise you will find the size reported in the start message when running the Proxmark3 client./pm3.
What has changed?
See the Changelog file which we try to keep updated.
Development
⚠ Note: This is a bleeding edge repository. The maintainers actively is working out of this repository and will be periodically re-structuring the code to make it easier to comprehend, navigate, build, test, and contribute to, so DO expect significant changes to code layout on a regular basis.
👉 Remember! If you intend to contribute to the code, please read the coding style notes first. We usually merge your contributions fast since we do like the idea of getting a functionality in the Proxmark3 and weed out the bugs afterwards.
The public roadmap is an excellent start to read if you are interesting in contributing.
Supported operating systems
This repo compiles nicely on
- WSL1 on Windows 10
- WSL2 on Windows 10/11
- Proxspace environment release v3.xx
- Windows/MinGW environment
- Ubuntu, ParrotOS, Gentoo, Pentoo, Kali, NetHunter, Arch Linux, Fedora, Debian, Raspbian
- Android / Termux
- macOS / Homebrew (or MacPorts, experimental) / Apple Silicon M1
- iOS (Jailbroken, rootful)
- Docker container
Precompiled binaries

Proxmark3 GUI
Most community driven GUI for Proxmark tends to be quite old and out-of-date. Here is a list of a few:
- Proxmark3 Universal GUI will work more or less.
- Proxmark3 GUI cross-compiled which is recently updated and claims to support latest source of this repo.
- Proxmark3_GUI simple gui in vb.net
