Anyone played around with mobile interception?

Post by Shyft » Thu Feb 21, 2013 3:36 pm

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 :P

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.
