About 50m Facebook accounts were imperilled by an attack that enabled hacker to take control over user’s account, Facebook uncovered on Friday.
The hacking happened because of a flaw in Facebook’s “View As” feature, which enables you to see your profile as others do. Users can type in a person’s name to get a comprehension of what can be seen when a specific individual is seeing their page.
According to Facebook, the attacker exploited three bugs that were introduced into the site’s “view as” feature in July 2017. “View as” allows users to see what their profile looks like to other users. The company does not yet know when the hack took place, but it said that it began an investigation after discovering unusual activity on 16 September.
In addition to the 50m accounts whose access tokens were taken, Facebook said that it would require 40m additional users who used the “view as” tool since July 2017 to log out of their accounts as a precaution. This will reset those users’ access tokens, protecting their accounts.
Facebook said it did this as a precautionary step, logging out anyone who used the “View As” feature whether their account was actually affected or not. Users who were logged out do not need to change their password to be protected. The rightful owners of affected accounts will be able to log in with their current username and password.
Currently, the “View As” feature is not available while Facebook works to rectify the problem, those who try to use this feature should see an error message.
At the point when Facebook reported the attack on its blog last Friday, it said affected users would get a notification at the top of their News Feed when logging back into their account explaining what occurred and what ventures to take moving ahead.
