Well-known security researchers will demonstrate how to hijack a GSM signal. With this method, cell phone conversations can be intercepted easily. Demos will take place Chris Paget, a leading security researchers enough, the mat annual DefCon in Las Vegas end of July 2010. Paget called the Base Station will be demonstrating the kind that can be deceptive counterfeit phones around so send voice calls to that device. He also will disclose any device used for the demo. As quoted from his personal blog, Tuesday (27/07/2010), Paget said it was preparing a few things that the demo was not ‘interfere’ in terms of privacy.

Armed with advice from the Electronic Frontier Foundation, the first thing mentioned is that the device Paget around the demo area will get a warning. “You will be warned clearly, that the use of mobile phones during the demo it means you agree to be tapped. If you do not agree, you should turn off the phone,” wrote Paget. Second, continued Paget, machines used for the demo will not have a disk. All data will be stored on a USB stick that after the demo will be directly destroyed by the EFF. Then, Paget will only use the transmission capacity 250mW (microwatt). Compare with 2W power of most mobile phones. Fourth, Paget claims will pursue all calls made during the demo will be redirected to the destination as much as possible. Although I can guarantee, he was also ready to divert emergency calls to local numbers.
