If you suspect that your Facebook account is compromised, you must change your password immediately. Then, if you use Facebook to log in to apps such as Spotify or Instagram then change those logins too. This will stop hackers from gaining access to these third-party services via your hacked Facebook account.
A hacked Facebook account can give hackers an unending supply of personal information. Hackers can make use of this information for nefarious purposes such as spamming people or sending fake credit card offers. Hackers can also use compromised accounts to send spammy messages or even post on your timeline (as if it was you who made the mistake).
One of the most popular ways hackers can gain access to an account is to exploit an error in Facebook’s application code. For instance, a vulnerability in the iOS Facebook app allowed hackers to hack cookies and take the iPhone user’s “access token.” These tokens are digital keys that allow them complete control over the user’s Facebook account — and, thanks to Single Sign-On, other websites the person is logged into using their Facebook credentials.
A hacker may also gain access to an account through brute force attacks. This technique involves guessing passwords, generally the most popular ones such as 1234567890 or 123456789. Lastly, hackers can also gain access to an account by scanning for compromised credentials.
