SnoopSnitch App uses radio signals to find nearby tracking devices
A new free App on the Google play market, created by security researchers Alex Senier, Karsten Nohl, and Tobias Engel from SRLabs in Berlin, called SnoopSnitch is now available. SnoopSnitch can detect and warn smartphone users if their devices are giving up their personal information and connecting to them. The security researchers presented their App at the recently concluded Chaos Computer Congress’ annual hackers conference in Hamburg.
The official Google Play listing reads: ‘SnoopSnitch collects and analyzes mobile radio data to make you aware of your mobile network security and to warn you about threats like fake base stations (IMSI catchers), user tracking, and SS7 attacks.’
The SnoopSnitch App scans for signals that indicate a switch from a legitimate tower to a International Mobile Subscriber Identity (IMSI) catcher aka ‘stingray’, where information may be being collected for intercepting mobile phone traffic and tracking the movement of smart-phone users.
The app can’t prevent a smart-phone from connecting to stingrays, but it does let a user know there is surveillance in a certain area.
