Summary
"NFC Hacking with Proxmark3" has been conducted during a school project, in which we analyzed the implementation of our NFC System. Which includes our on-campus cards, the printing system, snacks and drinks machines and the classroom doors. The additional output of this project was a (tested) guide on how to install the Proxmark3. For further details with regards to our project, concrete tests and more advanced commands please see our documentation Proxmark.pdf.
Requirements
Please see the Install Proxmark3 guide for a full overview of requirements. However, the Operating systems on which we tested the installation on are:
- Ubuntu 16.04/18.03
- Windows 10
- MacOS 10.x
In order to complete the "Introduction" described below, you have to complete the Install Proxmark3 guide first.
Introduction
This introduction should only give you a glimpse of the available commands and possibilities of the Proxmark3. The official Proxmark3-Repository as well as the more advanced Ice-Man-Fork Repository (both linked in the reference section) provide lots of functions, though most of them are still in their alpha stage and therefore still need a bit of user-tinkering in order to work well. For further commands and our security analysis of our university feel free to have a look at our documentation!
The Basics
After you have successfully completed the Install Proxmark3 guide, you should see a screen similar to this when connecting to your proxmark3:
