In April 2013 the Dungeons and Dragons Online interactive video game suffered a significant data breach affecting approximately 1.6 million players. The incident involved the exposure of sensitive user credentials which were subsequently traded on various underground hacking forums. The breach was primarily focused on the game forum database and included sensitive authentication details and personal identifiers. This security failure allowed unauthorized parties to access a large volume of player information potentially leading to account takeovers across other services where users reused their passwords.
