Riot says League of Legends and TFT source code stolen in cyberattack

The League of Legends and Teamfight Tactics developer suffered a social engineering attack on January 20, though it looks like player information is safe.

League of Legends and Teamfight Tactics developer Riot Games has given an update regarding data compromised by a recent social engineering attack it suffered.

“Over the weekend, our analysis confirmed source code for League, TFT, and a legacy anticheat platform were exfiltrated by the attackers”, Riot’s Twitter thread states. According to the studio, ransom demands have been made, though it says that it won’t pay.

Fortunately, Riot remains “confident” that neither player data nor personal information was compromised in the attack.

As a result of source code getting out, the studio remains wary of new cheats being developed. To combat this, it has kept a close eye on its anticheat, and has devs poised to “deploy fixes as quickly as possible if needed”.

Riot also warns that “a number of experimental features” have also been compromised, though it isn’t guaranteed that any of them will ever see a full release. As such, should you see anything floating around the web, be sure to not treat it as a given.

On January 20, Riot reported that “systems in our development environment were compromised.” As a result of this, there have been major delays to much of the content originally planned for the 13.2 patch cycle for both League and TFT.

Fortunately, players won’t have to wait too long for chunks of it, with Riot looking to implement B and even C patches to get it out. Additionally, the developer states that its “regular patch cadence going forward” shouldn’t be upset by the attack, with system repairs well underway.

Riot says that a full report on the attack will be released “in the future”.
