Cyber conflicts are fought in the shadows, but in the case of Russia’s invasion of Ukraine, it is a group that calls itself Anonymous that has made the most public declaration of war. Late on Thursday the hacker collective tweeted from an account linked to Anonymous, @YourAnonOne, that it had Vladimir Putin’s regime in its sights.

In the days since, the group has claimed credit for several cyber incidents including distributed denial of service attacks – where a site is rendered unreachable by being bombarded with traffic – that have brought down government websites and that of Russia Today, the state-backed news service. The DDoS attacks still appeared to be working on Sunday afternoon, with the official sites for the Kremlin and Ministry of Defence still inaccessible.
