Detecting Stingrays
Researchers are developing technologies that can detect IMSI-catchers: those fake cell phone towers that can be used to surveil people in the area.
This is good work, but it’s unclear to me whether these devices can detect all the newer IMSI-catchers that are being sold to governments worldwide.

I’ve been wondering: Stringrays report a new tower ID and then design so the phone favors it? Or do they re-use the tower ID of a nearby one? If they use a new one, is having the phone alert for new Tower IDs a help in determining the message might be intercepted? At least for someone like me that spends 90% of his time within the same 5 mile radius? (The phone app Tasker for Android shows Tower IDs of connectable cell phone towers, so it seems that information is accessible.)
