SilkRoadOnline.net

In 2012 the popular massively multiplayer online role playing game Silkroad Online suffered a major data breach affecting approximately 4 million unique users. The incident resulted in the exposure of a database containing 11 million records because new entries were generated for each server a user joined. The breach was particularly severe as it included plain text passwords and sensitive account details. The data was widely circulated in the underground hacking community and remains a classic example of early decade gaming platform vulnerabilities where lack of encryption led to total account compromise for millions of players globally.
