Yahoo: Hackers who hit 500M users may be ‘state-sponsored’

SAN FRANCISCO: 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.”
