I mean, "game cheats" might be an understatement. Bungie runs an online service, and Ring-1 is creating and selling millions of dollars worth of exploits that allow users to cheat at a game that includes financial transactions and competitive play, by exploiting the servers that run the game.

Successfully attacking their online service, while indicative of Bungie running an insecure service, would be considered a form of cybercrime, as compared to simply exploiting the game code on your machine. You can't legally make and sell hacking tools that exploit online services.

And cheating at competitive play with real-world stakes is fraud.
