The hackers who stole 780GB of data from Electronic Arts (EA) are now releasing some of the data on the internet.
The leaking of the stolen data comes after the cybercriminals tried to extort EA, the publisher behind gaming franchises like FIFA, The Sims and Battlefield but received no ransom.
"Few week ago we send email for ransome (sic) to EA but we don't get any response so we will posting the src (source)," one of the posts from the hackers read, according to Vice's Motherboard.
Motherboard also viewed a compressed 1.3GB cache of the files the hackers released, which included references to internal tools and EA's Origin game store.
"If they don't contact us or don't pay us we will keep posting it," the hackers said.
At the time of the hack the cybercriminals said the data they had stolen included the code for FIFA 21 as well as the code and tools for the Frostbite engine, which powers games like Star Wars Battlefront II and the Need For Speed franchise.
"We're aware of the recent posts by the alleged hackers and we are analysing the files released," EA said in a statement.
"At this time, we continue to believe that it does not contain data that poses any concern to player privacy, and we have no reason to believe that there is any material risk to our games, our business or our players.
"We continue to work with federal law enforcement officials as part of this ongoing criminal investigation."
The hackers had been advertising it for sale on underground forums, telling prospective purchasers "you have full capability of exploiting on all EA services".
EA had previously said security improvements had already been made in light of the attack and did not expect an impact on games or its business.
The hackers were reportedly able to breach the company's servers by purchasing a cookie for EA's Slack server for just $10 on an underground invite-only site called Genesis Market.
