If you make this mistake, your Facebook is more at risk of being hacked
You probably know someone whose Facebook account was hacked. You would think a company as large and powerful as Meta would be better at preventing that sort of thing, but it’s all too common.
Hackers hijack social media accounts to spread malware, steal personal and financial information and spread lies. And the problem is you may not even know your account was compromised until it’s too late. Tap or click here for the warning signs to look out for.
A hacker who gains access to one of your accounts can use it to cause damage elsewhere. This is why we recommend using unique logins with strong passwords across your accounts. A security researcher was able to hijack Facebook accounts by users logging in with their Gmail credentials.
Here’s the backstory
Do you log in to your Facebook account with Gmail? We’ve warned you about using the same account for multiple logins, and here’s a prime example of why you shouldn’t.
Security researcher Youssef Sammouda showed that a threat actor could hijack a Facebook account after stealing a Gmail OAuth id_token/code used to login to Facebook.
OAuth is a common authentication framework that lets you grant limited access from one application to another. You see this when you use your Facebook or Gmail account to log into other accounts. You get access to that account without providing it with your login credentials.
Sammouda was able to chain multiple bugs using Google OAuth to exploit a series of Facebook vulnerabilities. “We log out the user from their Facebook account, we force the login to the attacker’s Facebook account,” Sammouda told The Daily Swig.
Sammouda reported the bugs to Meta on Feb. 16, and the company fixed the issue on March 21. Meta paid Sammouda a bug bounty of $44,625 for his work.
