It has commands to: - - * read any kind of 125 kHz unidirectional tag - * simulate any kind of 125 kHz unidirectional tag - -(This is enough to perform all of the silly cloning attacks, like the -ones that I did at the Capitol in Sacramento, or anything involving -a Verichip. From a technical standpoint, these are not that exciting, -although the `software radio' architecture of the proxmark3 makes it -easy and fun to support new formats.) - -As a bonus, I include some code to use the 13.56 MHz hardware, so you can: - - * do anything that a (medium-range) ISO 15693 reader could - * read an ISO 14443 tag, if you know the higher-layer protocol - * pretend to be an ISO 14443 tag, if you know the higher-layer protocol - * snoop on an ISO 14443 transaction - -I am not actively developing any of this. I have other projects that -seem to be more useful. - -USING THE PACKAGE: - -The software tools required to build include: - - * cygwin or other unix-like tools for Windows - * devkitPro (http://wiki.devkitpro.org/index.php/Getting_Started/devkitARM) - * Xilinx's WebPack tools - * Modelsim (for test only) - * perl - -When installing devkitPro, you only need to install the compiler itself. Additional -support libraries are not required. - -Documentation is minimal, but see the doc/ directory for what exists. A -previous familiarity with the ARM, with digital signal processing, -and with embedded programming in general is assumed. - -The device is used through a specialized command line interface; for -example, to clone a Verichip, you might type: - - loread ; this reads the tag, and stores the - ; raw samples in memory on the ARM - - losamples ; then we download the samples to - ; the PC - - vchdemod clone ; demodulate the ID, and then put it - ; back in a format that we can replay - - losim ; and then replay it - -To read an ISO 15693 tag, you might type: - - hiread ; read the tag; this involves sending a - ; particular command, and then getting - ; the response (which is stored as raw - ; samples in memory on the ARM) - - hisamples ; then download those samples to the PC - - hi15demod ; and demod them to bits (and check the - ; CRC etc. at the same time) - -Notice that in both cases the signal processing mostly happened on the PC -side; that is of course not practical for a real reader, but it is easier -to initially write your code and debug on the PC side than on the ARM. As -long as you use integer math (and I do), it's trivial to port it over -when you're done. - -The USB driver and bootloader are documented (and available separately -for download, if you wish to use them in another project) at - - http://cq.cx/trivia.pl - - -OBTAINING HARDWARE: - -Most of the ultra-low-volume contract assemblers that have sprung up -(Screaming Circuits, the various cheap Asian suppliers, etc.) could put -something like this together with a reasonable yield. A run of around -a dozen units is probably cost-effective. The BOM includes (possibly- -outdated) component pricing, and everything is available from Digikey -and the usual distributors. - -If you've never assembled a modern circuit board by hand, then this is -not a good place to start. Some of the components (e.g. the crystals) -must not be assembled with a soldering iron, and require hot air. - -The schematics are included; the component values given are not -necessarily correct for all situations, but it should be possible to do -nearly anything you would want with appropriate population options. - -The printed circuit board artwork is also available, as Gerbers and an -Excellon drill file. - - -FUTURE PLANS, ENHANCEMENTS THAT YOU COULD MAKE: - -At some point I should write software involving a proper real-time -operating system for the ARM. I would then provide interrupt-driven -drivers for many of the peripherals that are polled now (the USB, -the data stream from the FPGA), which would make it easier to develop -complex applications. - -It would not be all that hard to implement the ISO 15693 reader properly -(with anticollision, all the commands supported, and so on)--the signal -processing is already written, so it is all straightforward applications -work. - -I have basic support for ISO 14443 as well: a sniffer, a simulated -tag, and a reader. It won't do anything useful unless you fill in the -high-layer protocol. - -Nicer (i.e., closer-to-optimal) implementations of all kinds of signal -processing would be useful as well. - -A practical implementation of the learning-the-tag's-ID-from-what-the- -reader-broadcasts-during-anticollision attacks would be relatively -straightforward. This would involve some signal processing on the FPGA, -but not much else after that. - -It would be neat to write a driver that could stream samples from the A/Ds -over USB to the PC, using the full available bandwidth of USB. I am not -yet sure what that would be good for, but surely something. This would -require a kernel-mode driver under Windows, though, which is more work. - - -LICENSING: - -This program is free software; you can redistribute it and/or modify -it under the terms of the GNU General Public License as published by -the Free Software Foundation; either version 2 of the License, or -(at your option) any later version. - -This program is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
