Yesterday, Facebook notified users of a massive data breach affecting over 50 million people. The breach had taken place three days earlier, on the afternoon of 25 September.
The social media giant says it doesn’t know exactly what kind of information has been compromised. However, in an updated statement yesterday, it did admit the hack affected those who use Facebook to log into other accounts.
How do you know if you’ve been impacted?
If you’ve been affected by the breach, Facebook logged you out of your account yesterday. The social network said it would also notify these people in a message on top of their News Feed about what happened.
However, an important thing to note: If you were logged out, you weren’t necessarily breached. Facebook has also logged out everyone who used the ‘View As’ feature since the vulnerability was introduced as a “precautionary measure”. The social network says this will require another 40 million people or more to log back into their accounts, adding: “We do not currently have any evidence that suggests these accounts have been compromised.”
Has the issue been fixed?
According to Facebook, yes. It believes it has fixed the security vulnerability, which enabled hackers to exploit a weakness in Facebook’s code to access the ‘View As’ privacy tool that allows users to see how their profile looks to other people.
