Blizzard has been granted almost 8 Million euro in court for damages that the German cheats en hacks maker, Bossland, caused by violating Blizzard's copyright. According to the judge, Bossland developed hacks to get around Blizzards anti-cheat technology, which is basically violating the US Digital Millennium Copyright Act as the company made the software available for the masses with related instructions how to use it.
The judge has forbidden Bossland to continue promoting and selling their product in the US. In July 2016, Blizzard sued Bossland for multiple cheat tools including the Overwatch cheat tool which showed the user all important stats from other players in game. As a results, a huge amount of cheaters were banned from the game. In public, Bossland announced that they were working on software to get around this detection technology causing the bans. This wasn't the only game on which Bossland anticipated. Also WoW, Diablo 3 and Heroes of the Storm were addressed.
It's not the first time Blizzard sues a cheat maker for violating the game play. Recently they won a case against LeagueSharp whom provided cheat software for League of Legends.
The blocked hacks include Watchover Tyrant, Demonbuddy, Stormbuddy, Hearthbuddy, and Honorbuddy, plus all other cheatsoftware regarding Blizzard games.
