Simple ways on how to hack a facebook account

The attacker first needs to click on the "Forgot account?" link on the Facebook.com homepage. Now, when asked for a phone number or email address linked to the target account, the hacker needs to provide the legitimate phone number.

The attacker then diverts the SMS containing a one-time passcode (OTP) to their own computer or phone, and can login to the target’s Facebook account.

The issue affects all Facebook users who have registered a phone number with Facebook and have authorized Facebook Texts.

Besides Facebook, researchers’ work shows that any service, including Gmail and Twitter, that uses SMS to verify its user accounts has left open doors for hackers to target its customers.

Although the network operators are unable to patch the hole sometime soon, there is little the smartphone users can do.

Do not link your phone number to social media sites, rather rely solely on emails to recover your Facebook or other social media accounts.
Use two-factor authentication that does not use SMS texts for receiving codes.
Use communication apps that offer "end-to-end encryption" to encrypt your data before it leaves your smartphone over your phone's standard calling feature.

Update: However, the important thing to note is that the issue has actually nothing to do with Facebook security or other website's security, instead it is the weakness in the telecom network.

"Because this technique [SSL exploitation] requires significant technical and financial investment, it is a very low risk for most people," Facebook spokesperson told The Hacker News.

"As an added precaution, we recommend turning on two-factor authentication, called Login Approvals, in your Facebook security settings. Doing this will disable recovery via SMS on your account so even if someone has your phone number, they'll still need your password to access your account."
