Hackers claim to have broken into the Russian prisoner database and displayed pictures of anti-Kremlin activist Aleksei Navalny while also stealing information on hundreds of thousands of Russian prisoners and their relatives, CNN reported on April 1, citing those said to be involved in the alleged breach. CNN reported that a message on the hacked website said: “Long live Aleksei Navalny.” CNN said the hackers were a “mix of nationalities,” including Russians and Ukrainians. Navalny died on February 16 at a remote Arctic prison in mysterious circumstances.
