[Scan-DC] Secret US spy program targeted Americans' cellphones

[Andrew Clegg]

Can phones really be purchased anonymously? I thought you always had to provide an ID of some sort. I don't believe you can walk into a CVS and buy a phone for cash without providing any identifying information, but I could be wrong. Next time I'm there I'll give it a try.

I found this link very interesting as I am sure it cuts both ways in send and receive. I would think a tethered blimp at 1000 ft. with directional antennas would be a better bet to scarfing up cell phone info since you do not have the Doppler effect per se, FAA in-flight rules and other hindrances. The other thing is a cell phone can be bought in any drugstore for 20.00 as a throw-away. Use it once in one location or even twice and toss it in the garbage and buy another one with a different IMEI number and card. What would be the point of having data on a phone bought anomalously in a CVS and tossed into a dumpster?

I'm not sure that this isn't feasible. The Open BTS project (openbts.org) has implemented GSM base stations on software-defined radio platforms for the last few years, and I've seen demonstrations of unsuspecting cellphones attaching. It would not be hard to spoof a carrier's base station and capture some basic data from a user. There is a corresponding  effort underway for a public-domain LTE implementation, but I don't think that project is complete. I would not be surprised, though, if the intelligence community is further along, if not already equipped with the capability for a full LTE implementation, especially if they had cooperation from the industry. In my opinion, what's described in the article is within the realm of possibility. The biggest challenge would be signal strength loss from a handset on the ground up to an airplane. I can imagine that strategically-placed terrestrial base stations would work better.
