RE: Retina-Nimda Scanner detects Win9x as infected...

[Stephen Villano <steve () LWR yi org>]

It would APPEAR that way. However I know for a fact that nimda was
contracted on a workstation on my network and never infected the server
where the "open guest access" was present. Then again I had the free Nimda
scanner from eEye scan port 80 when it detected that on my server, which is
using port 8080 instead of port 80, it detected NOTHING on port 8080 setting
scan of the same server.

Subject: Retina-Nimda Scanner detects Win9x as infected...


A scan with eEye's free Retina - Nimda Scanner on my network shows all
Windows 9x systems that have the "File and Printer Sharing for Microsoft
Networks" service installed on them as infected (Banner = Open Guest
Access).  Even though these systems have nothing shared out.  Once this
service is removed, the scan does not detect them.  The obvious conclusion
is that just by having that service on a system, (without actually sharing
anything) it is vulnerable to Nimda and other Trojan's.  Is that correct?
