So. I had some requests asking me about how I did what I did with GSM. What tools did I use, what hardware and what options?
Since I believe strongly that GSM needs to be “out in the hands of the people” meaning everybody should have access to cheap hardware and free, opensource software that helps understanding GSM in practice I thought I will create a series of write-ups describing the whole process from the beginning.
Third step: uncover the TMSI
The script I used at Hacktivity needs to be finalized, also the Android app (SilentSMS) needs some re-factoring, so this step is going to be released later.
UPDATE (19/10/2013): I started fixing the code, first up is the Android app which seems to be ready from my point of view, but since I haven’t checked it with anyone else I am going to say it is alpha quality code, a little bit better than a PoC.
