Facebook “Password Changed” E-mail Scam Spreading On Non Protected Machines

By Cesar Ortiz
Multiple sources are reporting that users are falling on this simple but malicious attack via e-mail. If you receive in your PC an e-mail message that says:

 Dear user of FaceBook. Your password is not safe! To secure your account the password has been changed automatically. Attached document contains a new password to your account and detailed information about new security measures.” Thank you for attention, Administration of Facebook.”

Delete the message and ignore it. It is a scam. (1) Did you notice that the name “FaceBook” is not written correctly on the salutation? (2)  Will Facebook staff do such a mistype?  (3) Why Facebook will send an attachment? (4) Did you tried login-off and login-in again to make sure your password was changed? The scam has several links, all directing users to click on an attached ZIP file that “contains a new password”. User problems begins when the attachment is opened, the computer is infected with the Trojan:Win32/LockScreen.AO. According to Microsoft, AO is a Trojan that gains control of the affected computer by locking the screen and preventing the user from accessing the desktop. It forces the user to send an SMS to a premium number to regain access to the computer (money for the hacker).

A blue and white screen that says “Windows ????????” is a sure indication that your computer got the malware. Almost all paid anti-virus and malware detection software providers will have the means to detect and remove or quarantine the virus. If you have none consider using one of the free versions or subscribe for a free trial. In a worse case scenario, with an already infected PC, press F8 when booting your PC, select “Safe Mode with networking”, open your Internet browser,  go to Kapersky Labs , download and run the Kaspersky Virus Removal Tool at the bottom of the screen. This is one of the free tools developed by Kaspersky for fighting some of the more popular viruses. Remember, Users common sense and caution, play a big role in preventing malware infections.
