Warning for Visitors to Ombudsman's Web site

This message describes a specific spyware risk for anyone who recently
visited the Office of the Ombudsman Web site, and a general warning to MSU
Webmasters about the use of third party Web page counter software.

On Friday, February 13, 2004, we discovered that the Ombudsman’s Web site,
http://www.msu.edu/unit/ombud/ , was attempting to download spyware.
(Spyware is software that attempts to locate personal information on your
computer, which it then forwards to others on the Internet.) The Ombudsman
site itself was not compromised; however, it was linking to an off-campus
Web page counter service, which in turn was serving a banner ad that
attempts to infect visitors’ computers.

Any computer used to visit the Ombudsman Web site before February 13 could
be infected with spyware. In some cases, anti-virus software may have
detected the intrusion attempt and prevented infection. In other cases,
spyware is able to infect computers even if you use anti-virus software.

After infection, the user’s Internet Explorer settings were changed, a
“tracking cookie” installed, and an Internet site called
findthewebsiteyouneed was accessed. Here is Symantec’s description of the
exploit tool used:

Spyware is a growing threat to privacy. You may become a victim of spyware
if you install certain software -- file sharing programs are notorious
examples – or through other means of infection. Specialized tools are
available to scan your computer in order to detect and remove spyware. Two
of the most popular anti-spyware tools are Ad-aware and Spybot. You can
download current versions of these tools from sites such as
http://download.com .

We also suggest that all computers be protected with current anti-virus
software. The MSU Computer Store offers anti-virus tools at deep discounts,
including McAfee anti-virus software for students for $10. See
http://cstore.msu.edu .

Also, all Windows users should run Windows Update on a regular basis in
order to reduce the threat posed by vulnerabilities in the Windows operating
system. See http://windowsupdate.microsoft.com .

Finally, we urge MSU Webmasters to avoid using third party page counters.
Using these page counters could expose your site visitors to similar risks.
Moreover, by revealing http referrer information, these services could
compromise the privacy of your site visitors, perhaps even violating MSU’s
Acceptable Use Policy. Consider using Web log analysis software that
aggregates statistics so as to preserve personal privacy in order to measure
your site’s popularity.
