Electronic Arts (EA), a game developer and publisher behind such popular brands as Madden NFL, EA SPORTS FIFA, Battlefield, The Sims, and Need for Speed, has suffered a security incident in which hackers stole a large trove of valuable information from the company.

The hackers claimed to have downloaded roughly 780 GB of data, including source code for games such as FIFA 21 and for the proprietary Frostbite game engine used as the base for many other high-profile games, as well as some debug tools.

According to Bleeping Computer, other stolen information includes FIFA 22 API keys and SDK & debug tools, debug tools, SDK, and API keys, proprietary EA games frameworks, XBOX and SONY private SDK & API key, XB PS and EA pfx and crt with key.

As proof of their claims the hackers shared several screenshots claiming to demonstrate their access to EA data, but they did not publish any of the stolen data. Based on advertisements on several underground forums, it appears that the hackers intend to sell the stolen information.

An Electronic Arts spokesperson said that the company is investigating the breach “where a limited amount of game source code and related tools were stolen.”

"No player data was accessed, and we have no reason to believe there is any risk to player privacy," the company said.

The "network intrusion" was not a ransomware attack and had happened recently, EA said, adding that it had already improved its security following the hack, and doesn’t expect an impact on its games or business.
