 U.S. penetrates Russian surveillance system used by FSB. More than 10 years ago, the U.S. special services could have hacked SOM, a Russian hardware and software system for monitoring telephone conversations, text messages and all message exchanges by residents of the Russian Federation on the Internet. Jacob Appelbaum, American hacker and journalist said this according to Medusa. If this really happened, information about the private lives of ordinary Russians was obtained not only by the Russian authorities but also by the American ones. Medusa said, Jacob Appelbaum claims that previously unpublished Edward Snowden documents refer to the hacking of Russian SOM by U.S. intelligence services. This follows from Appelbaum's dissertation, communication in a world of pervasive surveillance, which was defended at the Eindhoven University of Technology in the Netherlands in March 2022. Unpublished U.S. National Security Agency documents specifically point to the compromise of Russia's SOM lawful interception infrastructure as an example of the NSA's success in compromising civilian telecommunications infrastructure to spy on targets within reach of the Russian SOM system. On the NSA slides, there is the inscription, You talk, we listen, written in Cyrillic on the jackets of two Russian officers. Medusa said, Medusa believes that it refers to the period before 2013, when Snowden handed over the documents of the special services to journalists.
