New ham software to hack easily GSM signals (call and sms)

The ability to hack some GSM signals has been around for some time now, but the steps to reproduce the hack have been long and difficult to set up. Recently reader Bastien wrote into us to let us know about his recently released project called Topguw. Bastien’s Topguw is a Linux based program that helps piece together all the steps required in the GSM hacking process. Although the steps are simplified, you will still need some knowledge of how GSM works, have installed Airprobe and Kraken, and you’ll also need a 2TB rainbow table which keeps the barrier to this hack still quite high. Bastien writes about his software:

So like I said my software can “crack” SMS and call over GSM network. 

How ?

I put quotation marks in crack because my software is not enough to deciphered GSM itself. My software can make some steps of the known-plaintext attack, introduce by Karsten Nohl, and by the way, increase the time to decipher an SMS or call. I’ll not explain here all the steps because they are long and tedious, but there is a lot of work done behind the Gui.
