Massive hacker attack against the Russian public media conglomerate Vgtrk.

"Online broadcasts and internal services are down. Internet and telephones are also down. It will take a long time. I heard that they wiped everything from the servers, including the back up", testified a source, quoted by Gazeta.ru, defining the attack as "unprecedented".
