Yahoo Says Hackers Stole Data on 500 Million Users in 2014
SAN FRANCISCO — Yahoo announced on Thursday that the account information of at least 500 million users was stolen by hackers two years ago, in the biggest known intrusion of one company’s computer network.
In a statement, Yahoo said user information — including names, email addresses, telephone numbers, birth dates, encrypted passwords and, in some cases, security questions — was compromised in 2014 by what it believed was a “state-sponsored actor.”
While Yahoo did not name the country involved, how the company discovered the hack nearly two years after the fact offered a glimpse at the complicated and mysterious world of the underground web.
