This second blog post on the OSINT field will talk about Facebook. Again, it is a really simple tips but very interesting.
Facebook is probably the most known social network in the world. During the third trimester 2020, there were 1.82 billions active users each day!
To create an account on Facebook a simple e-mail address is required. This e-mail address can be publicly share with friends or with all users! But some users prefer to hide the mail address connected to their Facebook profile. In a OSINT point of view, it is sometimes important to know if a mail address is linked to a Facebook account.
There is, at least, one way to check if a mail address is used for a Facebook account.
To check the linked account, you have to be a Facebook page administrator. If you are not, you can create a page only for this purpose.
If your OSINT investigation must to be without interaction with anyone, pay attention to not click on the name displayed! It will be send a notification (and probably an email) to the user!
A lot of people share information on their Facebook profile. It is sometimes voluntary, but the default Facebook settings share some information with your friends (important to check times-to-times, because it is change often). A few years ago, it was possible to find a lot of pictures, likes,... published on Facebook thanks to Graph Search. Now, it is not possible to use this tool any more so, it is more difficult to collect data from Facebook but still possible!
One basic advise: check your Privacy settings on your account to know what are the informations share with who!
