Dailydave: Re: SIGINT and Telecommunications Intercept Capability of Cambodia

["matthew wollenweber" <mwollenweber () gmail com>]

It really depends on what you mean. It's not too hard to get a receiver that
can pick up GSM signals. Converting it to digital is a bit harder. Frequency
hopping.... getting expensive. Encryption -- depends on the version of GSM I
think. But you're talking about a nation state and as people said, almost
any nation state could replace your phone with custom hardware. Similarly
they can just query the telephone company.

I think the more fundamental question is can they possibly process a
reasonable amount of voice traffic for a large number of users? Data mining
itself is a monumental challenge. Converting (cellular) audio to something
that can be stored and analyzed in a reasonable manner is a huge endevour.

My final thought is that if you pissed someone off and they're targeting
you, then you're screwed. If you think the government is processing
everyone's cell calls -- i doubt they're doing it effectively.
