Yahoo has confirmed a massive breach that compromised the personal information of 500 million of its users, affecting account holders of Yahoo Mail, Yahoo Finance, Yahoo Fantasy Sports, and Flickr. The tech giant was quick to issue a plan of action, with Yahoo chief information security officer Bob Lord posting an announcement on Tumblr on September 22. The post outlines the investigation, a protection plan, and security recommendations. Yahoo also confirms that user account information was stolen in late 2014, and the data may have included names, passwords, security questions and answers, as well as other personal information like dates of birth and email addresses. Lord’s report noted that there is no evidence to suggest that user payment card data or bank account information was compromised—the system housing that information is believed to be unaffected.
