This video is boring and it's too long. This guy needs to get to the point of the discussion. Anyway people have been listing in to cellphone conversations for years, then there's the embarrassing reveal two years ago of the NSA spying on cellphone conversations for years.

I dont beleive the NSA was spying on cell phone conversations - just sifting thru metadata. Great video and very informative.

Interesting that the GSM base tower picks all of the settings to instruct the handset - I thought it was the other way around. For a couple thousand dollars you can intercept phone calls and meta data associated with those hand held devices and networks. IMSI catchers are being used by local police and intel agencies but does raise serious civil liberties and privacy issues.

Long but informative video. Cell phone spying is not something unheard or uncommon practice. Law enforcement agencies use it to tap suspect's phones.

As pointed out, I don't think most people know anything about the GSM base tower picking up the cell phone settings and instructing the handset. I also don't think most are aware that police and intel are listening in on some conversations. It was an interesting demo but took awhile to demonstrate the point.
