World of Warcraft and Diablo III developer Blizzardhas announced an intrusion into its internal network. Some data was illegally accessed, including the global Battle.net user email list outside of China, the answer to personal security questions on North American servers, encrypted Battle.net passwords, and information relating to Mobile app and Dial-in authenticators. According to Blizzard, the information alone isn't sufficient for unauthorized parties to gain access to Battle.net accounts.
