Raiatto Games Victim of Social Engineering Attack

On Saturday, January 21, 2023 (Japan time), RYAT Games reported a social engineering attack on its development environment systems. First of all, we would like to emphasize that there is no evidence that any player data or personal information was obtained.

Social engineering refers to methods other than information and communication technology used to obtain passwords and other information to break into a network. In other words, unlike hacking or cracking as commonly imagined, it takes advantage of human psychological gaps, weaknesses, or behavioral errors. Examples include "pretending to be an administrator on the phone and asking for passwords," "looking over one's shoulder to steal passwords," and "going through one's trash. For more information, please refer to the Ministry of Internal Affairs and Communications' information security website.

Actual Damage

The social engineering attack exposed the source code of "League of Legends" and "Teamfight Tactics" as well as previous anti-cheat platforms. The perpetrators also revealed that they received an email demanding a ransom. Of course, Riat Games has not responded to this demand.

The biggest concern about the release of these source codes is the "emergence of new cheats. Since the attack, Riat Games has been assessing the impact on anti-cheaters and preparing fixes if necessary.

The leaked source code includes many changes and prototypes of new game modes, but RYAT Games also emphasizes that these changes may not actually be released.

Future Policies

Riat Games' security team and external consultants continue to analyze the attack and audit its own systems. We have also notified legal authorities and are actively cooperating with them to investigate the attack and the group behind it.

RYAT Games plans to release a detailed report summarizing the techniques used by the perpetrators, the failures in RYAT Games' security controls, and measures to prevent a recurrence.

Impact on the Patch Cycle

Many of the titles developed by RYAT Games are regularly updated (patch releases), but there was concern that the damage could delay these content releases.

Since a lot of progress has been made between the damage and today, it has also been announced that the situation will be repaired by the end of this week (week of January 23, 2023), allowing us to maintain a regular update cycle in the future.
