Chris Paget, a security expert said that he has come up with a simple and low-cost way to eavesdrop on cellphone communications, claiming that most of the wireless networks are unequipped of assuring calls won’t be intercepted.
His technique only works with wireless systems based on GSM technology, which is used by most of the world’s wireless carriers.
“GSM is broken,” Paget said on Tuesday in a telephone interview. He said he plans to demonstrate his low-cost IMSI catcher by asking audience members to make calls using GSM phones, than tap into their conversations from the podium.
Thousands of hackers will attend the Defcon conference in Las Vegas that starts on Friday, where researchers like Paget will disclose security vulnerabilities in systems from cell phones and business software to systems that run the electrical grid.
