More than one million Russians are expected to be under wiretap surveillance by the end of 2016, Russian activists have reported.

Data collected by journalists Andrei Soldatov and Irina Borogan for their book "The Red Web: The Struggle Between Russia's Digital Dictators and the New Online Revolutionaries" shows that the number of wiretaps signed off by the Russian courts doubled between 2007 to 2015, jumping from 265,937 to 539,864.
