How to Hijack Facebook Email to Hack a Facebook Account?

If you know the primary email of a Facebook user, think that you have completed the half journey of hacking his/her Facebook account. The further task is to hack email account. When you have access to email account, you can easily reset password of Facebook through email address. In this way you can hack any Facebook account. But revealing the email of Facebook users is not easy if it is hidden behind security setting. However, 75% of emails on
Facebook are indirectly public regardless of how strictly the users have hidden it. Try the techniques given below.

1. Copy the username of a user and insert it in the username area.

2. Click on 'forgot your password.'

3. Insert the username again in the 'find your account' box and hit 'search'.

4, Guess easily what email the victim is using. Most of the emails match with the name of the the user.

5. Check the email whether it is right or wrong.

6. See another example.

7. Now, you know the email of the user. When you know the email of your victim, you can hack his/her email account by applying one of the following ways:
a. Getting physical access to the mobile of the user.
b. Getting access to the alternative email of the user.
c. Getting access to the government issued identity card like license, citizenship, etc.

Note: The Facebook users mentioned in the above illustrations are my friends. They are not hacked.

Important: I have already reported this vulnerability to the Facebook Team under White Hat Hacking Programme.
