What are Stingrays and IMSI catchers you ask?
IMSI catchers, otherwise known as stingrays, are those surveillance tools that masquerade as cell towers and trick mobile phones into connecting, spewing private data in the process. Law-enforcement agencies have been using them for awhile, but there's never been a good way for individuals to detect them. But that was before SnoopSnitch.
SnoopSnitch scans for radio signals that indicate a transition to a stingray from a legitimate cell tower.
"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 over-the-air updates."
And just when you though Mobile Phones where safe for private discussions, financial transactions and not to mention those unmentionable selfies.
