The FRITZ!Alert project is a software that allows you to monitor your network traffic in real time if you have an AVM FritzBox.
I started this project to detect P2P file sharing in my network reliably and save the evidence of the user which did share a file over P2P / torrents etc.
In my case I did not want to restrict the users of my network from their freedom of using whatever software they like, I just needed a solution for saving up evidence in case someone did something illegal. This is why I created this software.
At the time of writing I have not published the backend code yet.
Please understand that this software may not only help in clarifying illegal activities but may also be used with the intent of causing something illegal!
Another reason is that at the time of writing this software is not 100% tested, and therefore I could not publish it with a peace of conscience if the gathered evidence would somehow be falsified and used in a court case or something similar.
I will however publish bits and pieces of it in the future to make it a well-rounded proof-of-concept with no warranty!
You may however want to check out the live demonstration with no backend functionality.
I am open for discussion on this project.
