Phiningbrev från Microsoft

På "SANS Internet Storm Center" skriver Marcus H. Sachs att flera personer har hört av sig efter att ha fått falska e-postmeddelanden. Avsändaren ser ut att vara från Microsoft och i meddelandet uppmanas man att installera en kritisk säkerhetsuppdatering som är bifogad med brevet.

Subject: Security Update for OS Microsoft Windows
From: "Microsoft Official Update Center"

Dear Microsoft Customer,

Please notice that Microsoft company has recently issued a Security Update for OS Microsoft Windows. The update applies to the following OS versions: Microsoft Windows 98, Microsoft Windows 2000, Microsoft Windows Millenium, Microsoft Windows XP, Microsoft Windows Vista.

Please notice, that present update applies to high-priority updates category. In order to help protect your computer against security threats and performance problems, we strongly recommend you to install this update.

Since public distribution of this Update through the official website would have result in efficient creation of a malicious software, we made a decision to issue an experimental private version of an update for all Microsoft Windows OS users.

As your computer is set to receive notifications when new updates are available, you have received this notice.

In order to start the update, please follow the step-by-step instruction:
1. Run the file, that you have received along with this message.
2. Carefully follow all the instructions you see on the screen.

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. In that case, at this point the upgrade of your OS will be finished.

We apologize for any inconvenience this back order may be causing you.

Thank you,

Steve Lipner
Director of Security Assurance
Microsoft Corp.

E-postmeddelandet har även, enligt skribenten på SANS, en legitim PGP-signatur, och ser ut på detta sätt:

Version: PGP 7.1
