Virus Alert - Code Red Worm


Brink15

Recommended Posts

If you are running Windows NT (either workstation or server) or any of the W2K versions, go to Microsoft's website to get the Code Red Worm Patch:

quote:

Summary: The Code Red Worm and mutations of the worm pose a continued and serious threat to Internet users. Immediate action is required to combat this threat. Users who have deployed software that is vulnerable to the worm (Microsoft IIS Versions 4.0 and 5.0) must install, if they have not done so already, a vital security patch.

How Big Is The Problem? On July 19, the Code Red worm infected more than 250,000 systems in just 9 hours. The worm scans the Internet, identifies vulnerable systems, and infects these systems by installing itself. Each newly installed worm joins all the others causing the rate of scanning to grow rapidly. This uncontrolled growth in scanning directly decreases the speed of the Internet and can cause sporadic but widespread outages among all types of systems. Code Red is likely to start spreading again on July 31st, 2001 8:00 PM EDT and has mutated so that it may be even more dangerous. This spread has the potential to disrupt business and personal use of the Internet for applications such as electronic commerce, email and entertainment.

Who Must Act? Every organization or person who has Windows NT or Windows 2000 systems AND the IIS web server software may be vulnerable. IIS is installed automatically for many applications. If you are not certain, follow the instructions to determine whether you are running IIS 4.0 or 5.0. If you are using Windows 95, Windows 98, or Windows Me, there is no action that you need to take in response to this alert.

What To Do If You Are Vulnerable?

a. To rid your machine of the current worm, reboot your computer.

b. To protect your system from re-infection: Install the patch as specified in the instructions.

The security bulletin that describes the patch and the vulnerability it addresses is posted at:

Because of the importance of this threat, this alert is being made jointly by:

The above info from Microsoft indicates this is ONLY applicable if you run both IIS and NT or W2K. Several other reports indicate any O/S based on the NT kernel may be at risk.

This NO joke.

The most recent estimate is that it has infected over 300,000 new sytems since the report.
