If you ever encounter a message or a post in Facebook or in a Facebook application that makes you click a certain link,and the page that the link brought you to tells you to enter your Facebook login details again, please make sure that the URL of the login page is from Facebook.com.

Kindly look at this Facebook login page from some link from a Facebook mesage:

Pretty much the same as the Facebook login page,right? But if you look at the URL(the address bar encircled below), the URL address is not from Facebook.

Once you enter your details in the login form, they will save your info, and redirect you back to a Facebook application without you noticing it. Once they got your login information, they can access your profile and can do whatever they want with it(change password, delete profile, spam your friends, etc.). This type of hacking is called phishing, and still many persons don’t know this and is often victimized by it.

Just a friendly advise, if ever you are entering any login information or sensitive data in a form, always check the address bar if you are in the site you are accessing. This will prevent phishing attacks not only in your Facebook account but also in your accounts on other websites as well.
