In the meantime, they are quite capable of fixing selectively. The author can not say they do so or not, but knows exactly what is possible in principle to itself – have. Someone may say that, to example, the GSM standard, all negotiations on the radio – is encrypted. Serious and powerful. How to fix? My answer: encryption exists only on the radio at the same switch, all data are processed in unencrypted form and do not need any additional equipment, besides the standard interface to SORM to get full access to information. Further, everything happens for a standard scheme.
The same thing – and with Internet traffic: it can be encrypted on subscriber line service provider, but the provider works with unencrypted traffic. The exception applies only to tunnel junctions, when the public access network used to transmit traffic encrypted sender and that can only decode the recipient! So, the FSB officers have access to resources quite all communications providers and can quite arbitrarily listen to any calls, and analyze traffic any subscriber. But that's not all. Also, they can carry out the substitution rates. But they are not alone.
For example, the long evenings on the switch, the author invented a fun one: he cheated on most PBX her phone number and For example, when he phoned her friend, she determines the number of her beloved mother, and not the number of the author. This was done just by pressing a couple buttons on the keyboard. Exactly the same things can make employees KGB: the author made repeated calls to discharge the same way that it was determined the same author's own room! To demonstrate the possibilities, the staff has also been shown to have full access to all resources Stations provaydrov all, to the point that they can just temporarily disable multiple base stations with absolutely no knowledge of the provider. So if your cell phone lost network in the city center, it is quite possible, it is not technical issues, and information blockade during special opertsii. As you can see, the KGB about the opportunities that exist in the FSB, could only dream of, and hence the phrase: let's meet – it's not a phone conversation, not lose its relevance, rather the opposite – Big Brother is gaining momentum.
