How to check if your Facebook account was hacked

"As we look for other ways the people behind this attack used Facebook", the company said, "as well as the possibility of smaller-scale attacks, we'll continue to cooperate with the FBI, the US Federal Trade Commission, Irish Data Protection Commission, and other authorities".

The exact number hadn't been known before.

Facebook has revealed around 30 million accounts were affected by a recent security breach.

The hackers accessed name, email addresses or phone numbers from those 29 million accounts. The social media giant said users should visit Facebook's Help Center to see if their account was affected.

Facebook also said that hackers were unable to access any private messages, with one notable exception: Facebook page administrators who had received or exchanged messages in that role could have seen those messages exposed.

Initial worries that the token pilfering might have led to the compromise of third-party apps implementing Facebook Login turn out to be completely unfounded.

Facebook added that the bureau has asked it not to discuss who may be behind the attack.

Facebook said cyberattackers accessed that data plus additional information including gender, religion, hometown, birth date and places they had recently "checked in" to as visiting.

Using these initial accounts, the attacker used a bug in Facebook's code relating to a the "View As" feature to access the profiles of friends, which it believes existed since July past year.

This is very bad for Facebook.

Company officials declined to say what countries the hackers had targeted, but described the security breach as a "broad" attack. Facebook discovered the attack September 25.

The 30 million people who were affected will receive "customized messages" in the coming days, explaining what information the hackers might have accessed.

The vulnerability the hackers exploited existed from July 2017 through late last month, when Facebook noticed an unusual increase in use of its "view as" feature.

Rosen said the FBI investigation also limited what he could disclose about what the hackers' end-goal may have been, but maintained that Facebook had "no reason to believe this attack was related to the mid-term elections" in the U.S. Instead, Facebook is doing all it can to sweep this under the rug, once again only notifying affected users (full disclosure: I was one of them) with an innocuous link at the top of their News Feed.

The revelation is the latest black eye for Facebook as it tries to recover from the scandal that came to light earlier this year in which Cambridge Analytica funneled highly personal details of more than 80 million users to an organization supporting then-presidential candidate Donald Trump.
