Riot Games updated the fans with the situation about the recent security breach, stating the group responsible is now seeking material gain.
Now the company updated the fans with their findings about what was taken and what the perpetrators wanted.
The source code for the two games that launch from the same client is the main takeaway here although a legacy anti-cheat platform was also exfiltrated. Perpetrators later contacted Riot Games in an attempt to extort a ransom but the company refused.
Even though no personal information was leaked this way, there is still reason for warning. Namely, each time source code is leaked for any game, it increases the odds of seeing cheaters in the future.
League of Legends has been cheater-free for the vast majority of its history but cases of scripting have been witnessed in the past.
It's not impossible we will see more instances of this happening in the future but Riot's anti-cheat teams have been on point so far so there is good reason to be optimistic about them plugging this leak as well.
