“Yahoo said Thursday a massive attack on its network in 2014 allowed hackers to steal data from half a billion users and may have been “state sponsored.”
Yahoo, which confirmed details of the breach months after reports of a major hack, said its investigation concluded that “certain user account information was stolen” and that the attack came from “what it believes is a state-sponsored actor.”
“Based on the ongoing investigation, Yahoo believes that information associated with at least 500 million user accounts was stolen,” a statement from the US internet giant in what is likely the largest-ever breach from a single organization.
“Yahoo is working closely with law enforcement on this matter.”
The comments come after a report earlier this year quoting a security researcher saying some 200 million accounts may have been accessed and that hacked data was being offered for sale online.”
