The first thing you should do if you suspect that your Facebook account has been compromised is to change your password. Then, if you are using Facebook for logging into apps like Spotify or Instagram change your logins too. This will prevent the hacker from accessing these third-party services through your compromised Facebook account.
Hackers can find many personal details in compromised Facebook accounts. Hackers could make use of the information for malicious reasons like contacting people or sending fake credit card offers. They could also use the compromised account to send spam messages to friends, or share a status update on your timeline that includes your name (as in the case that you did it yourself).
One of digital rights management the most frequent methods hackers gain access to an account is to exploit an error in Facebook’s application code. For example, a bug in iOS’s Facebook application allowed hackers to hijack cookies and take an iPhone user’s “access token.” These tokens are digital keys that allow them complete control over the user’s Facebook account as well as, thanks to Single Sign-On, any other websites that the user connects to using their Facebook credentials.
Hackers may also gain access to accounts through brute-force attacks. This method involves figuring out a password, often the most frequently used ones like 123456789 or 1234567890. In addition, hackers could gain access to an account by scanning for compromised credentials. There are several tools for free that can be used to scan for stolen information, including the popular website called HaveIBeenPwned.
