Hackers have broken into gaming giant Electronic Arts, the publisher of Battlefield, FIFA, and The Sims, and stole a wealth of game source code and related internal tools. “You have full capability of exploiting on all EA services,” the hackers claimed in various posts on underground hacking forums. A source with access to the forums, some of which are locked from public view, provided Motherboard with screenshots of the messages. In those forum posts the hackers said they have taken the source code for FIFA 21, as well as code for its matchmaking server. The hackers also said they have obtained source code and tools for the Frostbite engine, which powers a number of EA games including Battlefield. Other stolen information includes proprietary EA frameworks and software development kits (SDKs), bundles of code that can make game development more streamlined. In all, the hackers say they have 780GB of data and are advertising it for sale in various underground hacking forum posts viewed by Motherboard.
