It was simple and quick
Recently EA games was breached by hackers that involved gigabytes of private data stolen including the source code of some of their games.
The hacker group stole the source code for FIFA 21 as well as the source code for the Frostbite engine that powers game like Battlefield and other internal game development tools.
As a whole, the hackers claim they have 780GB of data and are advertising it for sale on the various dark web and hacking forums.
Now Motherboard is reporting that the group of hackers broke into the company in part by tricking an employee over Slack to provide a login token.
What actually happened?
One of the hackers from the group spoke to Motherboard via online chat and revealed the actual act that was performed as part of the breach.
It all started by purchasing stolen cookies for just $10 and using those to gain access to a Slack channel used by EA.
For starters, cookies are blocks of data that save the login details of particular users, and potentially let hackers log into services as that person.
In this case, the hackers were able to get into EA’s Slack using the stolen cookie.
The hackers then requested a multifactor authentication token from EA IT support to gain access to EA’s corporate network. The representative said this was successful two times.
After entering into EA’s network, the hackers found a service for EA developers for compiling games.
They successfully logged in and created a virtual machine giving them more visibility into the network, and then accessed one more service and downloaded game source code.
The representative for the hackers also provided screenshots to help corroborate the various steps of the hack, including the Slack chats themselves.

Furthermore, the hacker also provided Motherboard with a series of documents they say were stolen as part of the hack.
It included confidential materials on PlayStation VR, how EA creates digital crowds in the FIFA games and documents about AI in games.
