Defend Your Sensitive Mobile Communications

Against IMSI Catchers/Stingrays

Efani’s mobile government solutions provide the protection that public sector organizations need to carry out their mandates securely.

IMSI Catchers: Part of Today’s Digital Threat Landscape

IMSI catchers, commonly known by the brand name Stingray, are essentially spoof cellular towers used to intercept calls, texts, and any other information being shared using mobile devices.

About the size of a laptop computer, IMSI catchers can be used from a hotel room, car, coffee shop or drone, and pose significant risks to our national security. They are commonly used by malicious actors, including criminal organizations and the intelligence agencies of hostile foreign governments.

Ironically, IMSI catchers started out as a law enforcement technology. Since the late 1990s, however, almost anyone with the expertise has been able to build one using about $1,000 in parts and instructions freely available online.

As with all technologies, now that IMSI catchers have emerged from Pandora’s box, there’s no way to put them back in. But organizations can still take steps to defend themselves.
