Worm Planted in Fake Microsoft Security Update

It's Tuesday, time for more security patches from Microsoft right? Not quite. It seems the malware crowd is exploiting Microsoft's routine of releasing fixes on Tuesdays and sending out fake security emails bent on infecting their targets with a worm.

Windows users familiar with Microsoft's modus operandi will sniff out this scam immediately, though, and not only because of the cracked English in the message. The missive contains the security update in an attachment. Microsoft never sends security updates in attachments.

"Please notice that Microsoft company [sic] has recently issued a Security Update for OS Microsoft Windows," the fake notice reads in typical fractured prose. It then goes on to give instructions for installing the fake security file, KB453396-ENU.exe. "If nothing changes after you have run the file, probably in the settings of your OS you have an indication to run all the updates at a background routine," it explained.
