A PoC tool and documentation about the italian Ecozona card and how to crack it.
This page is only about documenting and reporting how weak and easy this system can be. This is not meant to be used actively and it's considered a felony.
The full and detailed explanation of how is it possible to modify the card content it's available in the docs page
I'm also working on a GUI tool that enables any Linux user to deal with the card easily. It's still work in progress and I'm coding it just because I need to train with Qt, if you want to understand (and in case fix ) how the exploit works, check the docs page.
