Nimda and Code Red certainly set another precedent for the danger of worms, and they are not harmless. Nimda creates open network shares on infected computers, and it also creates a Guest account with Administrator privileges, thus allowing access to the system and opening it up to whatever a knowledgeable hacker wants to do to it. Code Red (and its variant, Code Red II, which also opened a backdoor for the attacker) defaces Web sites, degrades system performance, and causes instability by spawning multiple threads and using bandwidth.
