A security flaw has led to the personal information of 50 million Facebook customers being compromised.
The breach, which was discovered on 25 September, was caused by unknown hackers exploiting a weakness in the ‘View As’ feature of the social networking service, which led them to gain control of user’s accounts.
Those who had been potentially affected were prompted to log-in again, although they did not have to change their passwords.
Guy Rosen, the company’s Vice-president of Product Management, said that all affected accounts had been reset, along with a further 40 million as a precaution.
The social media giant – which has more than two billion active monthly users – confirmed that the accounts of Facebook founder Mark Zuckerberg and Chief Operating Officer Sheryl Sandberg were among those compromised.
Hackers will also have been able to log in to other accounts that use Facebook’s system, including AirBnB and the dating app Tinder.
Rosen said: "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."
Facebook recently faced criticism over the Cambridge Analytica data scandal, while the firm is also struggling to convince lawmakers in the US and elsewhere that it is capable of protecting the data of users.
