The AllFacebook blog reports that people are receiving e-mails and messages in their inboxes with links such as "areps.at." Clicking it takes you to a fake Facebeook login page. If you enter your information, the site will quickly login to your account and change your password, blocking you from Facebook,. It will then forward a malicious link to all of your friends via your account.
