MENLO PARK, Calif. — Almost 30 million Facebook users’ phone numbers and email addresses were accessed by hackers in the biggest security breach in the company’s history, Facebook said on Friday. The attackers accessed even more details on 14 million of those users, including the area where they live, their relationship status and their religion.
The new details come two weeks after Facebook first announced that attackers had access to 50 million users’ accounts — meaning they could have logged in as those users. Facebook said on Friday that, “We now know that fewer people were impacted than we originally thought,” and said that 30 million people had been impacted.
Despite Friday’s announcement, there are still many details about the hack that have not been made public, including who was behind it.
The attack prompted Facebook to take the unprecedented step of logging out the 50 million users whose accounts were exposed and logged out another 40 million users as a precautionary measure.
