A Moscow court on Thursday jailed the leader of a notorious hacking group for two years for breaking into the accounts of high-ranking Russian officials.

Vladimir Anikeyev headed the Shaltai Boltai collective — Russian for “Humpty Dumpty” — believed to be behind high-profile hacks, including into the Twitter account of Prime Minister Dmitry Medvedev.

Anikeyev — who has been under arrest since October 2016 — was found guilty of gaining unauthorised access to computer data after a closed trial that was classified as “secret”, the court said in a statement.
