Yahoo has just confirmed that more than 1 billion accounts got hacked in 2013 by what the company believes to be a “state-sponsored actor” that was also responsible for breaching 500 million accounts in a separate attack that the firm announced earlier this year.
Yahoo said in a lengthy security announcement that information provided by law enforcement and which were closely analyzed by the company indicated that third parties were able to access Yahoo user data, and after investigations conducted by both the firm and outside forensic experts, they “found that it appears to be Yahoo user data.”
