Facebook says almost 50 million of its users were left exposed by a security flaw.
The company said attackers were able to exploit a vulnerability in a feature known as “View As” to gain control of people’s accounts.
The breach was discovered on Tuesday, Facebook said, and it has informed police.
Users that had potentially been affected were prompted to re-log-in on Friday.

Facebook hate speech glitch investigated by firm
The flaw has been fixed, wrote the firm’s vice-president of product management, Guy Rosen, adding all affected accounts had been reset, as well as another 40 million “as a precautionary step”.
Facebook – which saw its share price drop more than 3% on Friday – has more than two billion active monthly users.
The company has confirmed to reporters that the breach would allow hackers to log in to other accounts that use Facebook’s system, of which there are many.
This means other major sites, such as AirBnB and Tinder, may also be affected.

Who has been affected?
The firm would not say where in the world the 50 million users are, but it has informed Irish data regulators, where Facebook’s European subsidiary is based.
The company said the users prompted to log-in again did not have to change their passwords.
“Since we’ve only just started our investigation, we have yet to determine whether these accounts were misused or any information accessed. We also don’t know who’s behind these attacks or where they’re based. “
He added: “People’s privacy and security is incredibly important, and we’re sorry this happened.”
The company has confirmed that Facebook founder Mark Zuckerberg and its chief operating officer Sheryl Sandberg were among the 50 million accounts affected.

What is ‘View As’?
Facebook’s “View As” function is a privacy feature that allows people to see what their own profile looks to other users, making it clear what information is viewable to their friends, friends of friends, or the public.
Attackers found multiple bugs in this feature that “allowed them to steal Facebook access tokens, which they could then use to take over people’s accounts”, Mr Rosen explained.
“Access tokens are the equivalent of digital keys that keep people logged in to Facebook so they don’t need to re-enter their password every time they use the app,” he added.

What does this mean for Facebook?
The breach comes at a time when the firm is struggling to convince lawmakers in the US and beyond, that it is capable of protecting user data.
Facebook founder Mark Zuckerberg said on a conference call on Friday that the firm took security seriously, in the face of what he said were constant attacks by bad actors.
But Jeff Pollard, vice-president and principal analyst at Forrester, said the fact Facebook held so much data meant it should be prepared for such attacks.
“Attackers go where the data is, and that has made Facebook an obvious target,” he said. “The main concern here is that one feature of the platform allowed attackers to harvest the data of tens of millions of users.
“This indicates that Facebook needs to make limiting access to data a priority for users, APIs, and features.”
When asked by the BBC, Facebook was unable to say if the investigation would look into why the bugs were missed, or if anyone at the company would be held accountable for the breach.
