The first thing you need to do if you suspect that your Facebook account has been compromised is to change your password. If you use Facebook as a login to apps like Spotify or Instagram then you must change the logins. This will prevent the hacker from accessing those third-party services app-ink.net/what-you-should-know-about-youtube-music through your compromised Facebook profile.
Hackers can uncover many personal details in hacked Facebook accounts. Hackers could use this information for malicious reasons, like getting credit card numbers, and spamming people with fake credit card offers or scams that involve phishing. Hackers can also use compromised accounts to send out spam messages or even post on your timeline (as if it was you who was responsible).
One of the most frequent ways hackers get into an account is to exploit an error in Facebook’s application code. A bug in the iOS Facebook application allows hackers to take over cookies and steal the “access token” of an iPhone user. These tokens are digital keys, grant them complete control over the user’s Facebook Account, as well as any other websites they visit using their Facebook credentials.
Hackers also have the ability to gain access to accounts through brute-force attacks. This technique involves guessing the password, usually the most commonly used ones like 123456789, or 1234567890. Hackers gain access to accounts by scanning compromised credentials. There are several free tools that can be used to check for stolen data, including the popular website called HaveIBeenPwned.
