Computer science researchers Denis Foo Kune, associate professors Nick Hopper and Yongdae Kim, and undergraduate student John Koelndorfer have discovered that cell phone hackers can track your physical location without your knowledge. Using a cheap phone, readily available equipment, and no direct help from a service provider, hackers can listen to unencrypted broadcast messages from cell phone towers.
The group described their work in a recently released paper “Location Leaks on the GSM Air Interface” which was presented at the 19th Annual Network & Distributed System Security Symposium in San Diego, California. The research has received extensive media coverage both locally in the StarTribune, on MPR, KMSP, Fox9 and others as well as global coverage on various tech news websites. You can read their full paper; Location Leaks on the GSM Air Interface (pdf).
