An Update on the Code Red Worm
The Code Red Worm hit the Internet in July, exploiting a vulnerability in Microsoft's IIS software that was announced in June. The writer(s) of Code Red took advantage of hundreds of thousands of unpatched IIS servers worldwide to launch what could have been a distributed denial of service (DDoS) attack on the White House web site. While the DDoS attack itself might not have been successful, we all were part of history -- Code Red was self-propagating throughout the Internet turning servers into DDoS agents ("zombies"), waiting for the trigger to launch an attack. This kind of thing has been predicted for years.
This presentation provides an overview of the Code Red Worm, describes how it works, and offers suggested counter-measures. URLs for many Internet sites with patches, tools, and additional information are also provided.
