50 Million accounts exposed after Facebook security breach. Facebook has revealed that almost 50 million of its users accounts were left exposed due to a security flaw. Facebook has more than two billion active monthly users, making security a high priority concern. The security breach has caused Facebook’s shares to drop by 3% on Friday, 28 September.
The breach was discovered this week, and is the latest controversy surrounding Facebook after British company Cambridge Analytica gained access to information of 87 million users, and the controversy surrounding disinformation in elections. However, this breach has been the largest in the company’s 14-year history.
Facebook has said the attackers exploited two bugs in the site’s “View as” feature. The feature, which was designed to give users a clearer view of their presence and more control over their privacy, allows users to check what information other people can see about them. The flaw allowed users to gain “access tokens” which allow access to accounts, through Facebook’s video-uploading program for birthday celebrations. Although it’s not yet known when the attack happened, it seems to occurred after the video-uploading program was introduced. Attacked attempted to harvest user’s personal identifiable information (PII). After the attack was discovered, Facebook forced 90 million users to log out. Facebook has not announced where in the world the 50 million users are.
There have been some major changes in Facebook’s security teams after its Chief Security Officer, Alex Stamos left in August this year for a teaching position at Stanford University. Facebook decided to split the team members so that security employees work within different teams across the company, in order to make security an innate part of Facebook.
Facebook’s data breach was a trending topic on Friday with users posting the breaking story as news outlets released it. User’s found that some of their posts were removed because Facebook’s algorithm saw them as suspicious activity or spam.
