Recently, Facebook has disclosed a widespread security flaw that has affected many Facebook accounts. The security breach allowed hackers or other malicious third parties to access an affected user’s account by extracting their security token. According to the reports, the flaw has affected as many as 50 million people. Moreover, around 90 million users now have to log back into their accounts to be safe.
Hacker Stole Login Information of 50 Million Facebook Accounts
The security breach was tied to a vulnerability in the code that impacted “View As”. It is a feature that lets people see what their own profile looks like to someone else. Hackers exploited that vulnerability. Moreover, it allowed them to steal Facebook access tokens. It helped them to take over 50 Million people’s accounts.
Access tokens are actually the digital keys that keep people logged into the social network. It helps them in a way so that they don’t have to re-enter their password every time they use the app. The access tokens for the 50 million accounts have been reset.
If your account was among those who got affected, then you will find yourself logged out of Facebook. You will have to log back in. However, there is no need to change your password as attackers never had access to it. The CEO Mark Zuckerberg stated that:
“On Tuesday, we discovered that an attacker exploited a technical vulnerability to steal access tokens that would allow them to log into about 50 million people’s accounts on Facebook”
Facebook informed the Law enforcement agencies about the breach. According to them, the vulnerability has now fixed. Moreover, a Taiwanese hacker by the name of Chang Chi-yuan has also pledged to delete Zuckerberg’s personal page on Sunday. He revealed that he wanted to demonstrate some type of security flaw in Facebook. Let’s see will it happen or not.
