(PhysOrg.com) -- Researchers have demonstrated how it is possible to use GSM (Global System for Mobile communications) data along with a few tools to track down a person’s mobile phone number and their location, and even listen in on calls and voicemail messages.
Independent researcher Nick DePetrillo and security consultant Don Bailey demonstrated their system at the SOURCE Boston security conference earlier this week. Using information from the GSM network they could identify a mobile phone user’s location, and they showed how they could easily create dossiers on people’s lives and their behavior and business dealings. They also demonstrated how they were able to identify a government contractor for the US Department of Homeland Security through analyzing phone numbers and caller IDs.
Bailey and DePetrillo’s demonstration showed up inherent weaknesses in the way mobile providers expose interfaces to each other to interoperate over the GSM infrastructure. They used the Home Location Registry (HLR) and GSM provider caller ID database, along with some of their own tools and voicemail-hacking techniques.
