Japanese game developer Koei Tecmo has disclosed a data breach and taken their European and American websites offline after stolen data was posted to a hacker forum.
Since learning of the attack, Koei Tecmo released a data breach advisory stating that a forum on a UK subsidiary's website was compromised and the stolen data was leaked online.
The user data that may have been leaked through hacking is perceived to be the account names and related password and/or registered e-mail address," Koei Tecmo disclosed in a data breach advisory.
Update 12/28/30: The hacker behind the breach contacted BleepingComputer and stated that they leaked the data because Koei Tecmo failed to follow GDPR guidelines.
"From 25 May 2018, the General Data Protection Regulation introduces a requirement for organizations to report personal data breaches to the relevant supervisory authority, where the breach presents a risk to the affected individuals. Organizations must do this within 72 hours of becoming aware of the breach."
