Your Phone, the Snitch
Posted on Jul 10, 2012
Devices that intercept calls and text messages and dig into data stored on your mobile phone are being marketed to police departments across the United States “as being perfect for covert operations in public order situations.” Or, as the ACLU’s Privacy SOS blog puts it: protests.
IMSI, which stands for the dull and deceptively innocuous-sounding “International Mobile Subscriber Identity,” acts as a mobile phone tower that tricks cellphones into sending data to it instead of a nearby tower. Such “man-in-the- middle” attacks defy detection, usually occurring without the caller’s knowledge.
Police departments say they do not need warrants to use IMSI catchers. A case on the matter is working its way through the courts. The FBI already uses the device. Except for turning your cellphone off, there appears at the moment to be no way to shield yourself from such attacks.
