Leaky Cellphone Nets Can Give Attackers Your Location

Posted by samzenpus on Sunday February 19, 2012 @04:06PM from the there-you-are dept.

alphadogg writes "GSM cellular networks leak enough location data to give third-parties secret access to cellphone users' whereabouts, according to new University of Minnesota research. 'We have shown that there is enough information leaking from the lower layers of the GSM communication stack to enable an attacker to perform location tests on a victim's device. We have shown that those tests can be performed silently without a user being aware by aborting PSTN calls before they complete,' write the authors, from the College of Science and Engineering, in a paper titled 'Location Leaks on the GSM Air Interface' (Pdf). The researchers are working with carriers and equipment makers, including AT&T and Nokia, to address the security issues."

I'm trying to think of one thing someone could do to me armed with knowldege of my current location.
1. Determine that you're far away from home while they burglarize your house.
2. Determine that you were in the vicinity of a burglarized house and throw you behind bars without a warrant for 48 hours while they try to find evidence.
3. Determine you were someplace "unsavory" and use it as blackmail, or to deny you future employment, etc.
