On July 16, 2001, vulnerabilities in the Windows
Internet Information Services Server (IIS) made media headlines when the
computer worms Code Red I and
later Code Red II propagated within hours of each other and moved rapidly
across the Internet, taking over every vulnerable computer on the Internet.
By definition, a worm is a virus-like program that spreads
from one computer to another without human intervention. Code Red II was
especially dangerous because it altered approximately 100,000 Windows NT and
Windows 2000 Web servers on the Internet and PCs, permitting any unauthorized
user to log onto them and exercise total control. As of August 10, 2001,
Symantec Security Response created a tool to perform a vulnerability assessment of computers
and to remove both Code Red I and II.
