- Nimda mass mailing worm. It uses various known IIS
- vulnerabilities to compromise the server.
-
- Anyone visiting compromised Web servers will be prompted to
- download an .eml (Outlook Express) email file, which
- contains the worm as an attachment.
-
- Also, the worm will create open network shares on the infected
- computer, allowing access to the system. During this process
- the worm creates the guest account with Administrator privileges.
-
- Solution: Take this server offline immediately, rebuild it and
- apply ALL vendor patches and security updates before reconnecting
- server to the internet, as well as security settings discussed in
- Additional Information section of Microsoft's web site at
-
- http://www.microsoft.com/technet/security/bulletin/ms01-044.mspx
-
- Check ALL of your local Microsoft based workstations for infection.
- Note: this worm has already infected more than 500,000 computers
- worldwide since its release in late 2001.
