Secret Stingray Warrantless Cellphone Tracking
Penurious Penguin writes "Last year a Slashdot story mentioned the case of Daniel David Rigmaiden, or 'the Hacker.' With the help of an IMSI-catcher device, law enforcement had been able to locate and arrest the elusive 'Hacker,' leading to U.S. v. Rigmaiden. But far more elusive than the 'Hacker,' is the IMSI-catcher device itself — particularly the legalities governing its use. The secrecy and unconstitutionality of these Man In The Middle devices, i.e. 'stingrays,' has caught some attention. The EFF and ACLU have submitted an amicus brief in the Rigmaiden case; and EPIC, after filing an FOIA request in February and receiving a grossly redacted 67 out of 25,000 (6,000 classified) pages on the "stingray" devices, has now requested a district judge expedite disclosure of all documents. Some Judges also seem wary of the 'stingray,' having expressed concerns that their use violates the Fourth Amendment; and additionally, that information explaining how the technology is used remains too obscure. Perhaps the most controversial aspect of ISMI-catchers is their several-kilometer range. When a "stingray" is used to spoof a cellphone tower, thousands of innocent users may be collaterally involved. And while the government claims to delete all gathered data unrelated to the target, it also means no one else can know what that data really was. The government claims that because only attributes of calls — but not their content — are captured in the attack, search warrants aren't necessary."(More, below.) Read more of this story at Slashdot.
