The latest notice covers personal data identified as leaked during the ongoing investigation. No new breaches have occurred.
On the 21st, Kakao Games announced on its website that personal information of 103 RINK (Link) users had been additionally leaked. The leaked data includes company-assigned identification codes and country codes (for some users). Identification codes refer to codes arbitrarily assigned by the company for member identification purposes.
Previously, the company announced on the 16th that personal information of 140 users from "Partners" and RINK had been leaked. The company explained that no important personal information such as names, addresses, or gender was identified as compromised in this incident either. Kakao Games is currently investigating the specific cause and scope of impact with relevant institutional investors and security experts.
Kakao Games confirmed the leak of personal information for 103 users at 6:22 p.m. on the 21st. The hacking attack is estimated to have occurred between 10:44 p.m. on the 12th and 7:37 p.m. the following day (the 13th). Upon becoming aware of the incident, Kakao Games immediately blocked access paths and implemented emergency measures.
The company has reported the incident to relevant institutional investors, including the Personal Information Protection Commission, and is currently investigating the cause of the breach and the exact scope of damage in collaboration with external security experts. The scope of damage may expand depending on investigation results. Users whose personal information was leaked have been individually notified via email. A "Personal Information Violation Inquiry Page" has also been established for public notice of the incident. Logs and evidence related to the breach have been secured.
RINK is a service that streams game screens from Kakao Games running on a PC to a smartphone app for remote control. It stands for "Remote play IN Kakaogames." Partners is a program that collaborates with creators or general users to produce content for promoting the company's games.
