Anyone played around with mobile interception?
I'm thinking something along these lines will be my next project. I watched the Defcon talk from a couple of years ago and it got me interested. So has anyone here played around with intercepting mobile phone traffic, or setting up OpenBTS/IMSI catcher? Are you using a USRP or a cheaper alternative? What's your software/hardware setup? Have you had much success? Encountered any major problems? etc.

Only interception i have been involved in was back in the old analog mobile days, with a few modified motorola mobiles, remember how you could put them in programming mode / test mode and open up the monitor and tx feature, and could select the channel number, lol good times

the way it works now is it sniffs the 3G and saves it to a file and the contents have to be deciphered. I read about it 3 years ago. So 3G is not even worth apparently trying to listen in (cant be done on the fly)

USRP has been tried & tested, the OpenBTS team have dedicated hardware but that's more expensive and less flexible than a USRP.

The RTL-SDR is all the rage these days and only costs around $10. Interestingly enough you can use it to pick up GSM signals along with a whole bunch of other stuff.
