Submitted by Penurious Penguin
Penurious Penguin (2687307) 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, e.g. "stingrays", has caught some attention. The EFF and ACLU have submitted an amicus brief in the Rigmaiden case; and EPIC, who after filing a FOIA in February and receiving a grossly redacted 67 out of 25,000 (6,000 classified) pages on the "stingray" devices, is now requesting 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. The use of a pen-register (outgoing) and trap & trace (incoming) device, requires little more than a mewl of penal curiosity before a court, and no warrant or follow-up on the case is needed. The pen/trap seems unwieldy enough, as the EFF explains:

Most worrisome, we've heard some reports of the government using pen/trap taps to intercept content that should require a wiretap order: specifically, the content of SMS text messages, as well as "post-cut-through dialed digits" (digits you dial after your call is connected, like your banking PIN number, your prescription refill numbers, or your vote for American Idol). intercept information about your Internet communications as well.

Precisely what data these "stingrays" collect will hopefully be soon revealed through such efforts as those of EPIC.
It should be noted that the Stingray is one of multiple devices with the same application. The Stingray and several others are trademarks of the Harrison Corporation. Some are quite pricey ($75,000), and others are, as mentioned last year by a Slashdot reader, peculiarly affordable — and available.

  • If this submission is of any interest, it looks like it will need some editing. I was unable to discover why the final paragraph is italicized, and those above may be a bit wordy. It was somewhat of a beast to try to summarize, at least for me.

      I do hope that this submit gets accepted.

      It is way too important to NOT let any government entity to get off so easily with black-project-devices such as "stingray" which they will definitely use to spy on the citizens.

      And the most dangerous aspect on this case is that the government in question is not the government of Iran or North Korea or Russia or Cuba or China.

      Rather, it is the government of the United States of America which is employing such devices to spy on its own citizens !!

      It has gone way beyon

Heuristics are bug ridden by definition. If they didn't have bugs, then they'd be algorithms.
