The NIMDA Worm
Code Red meets I Love You
It was just over two months ago that the Code Red I and II worms hit the Internet, exploiting a vulnerability in Microsoft's IIS software. And it was well over two years ago that viruses started to self-propagate via e-mail.
Today we are experiencing the Nimda worm. Nimda is more potent than any single previous virus/worm because it takes advantage of more flaws. Nimda has four separate and distinct propagation vectors by exploiting vulnerabilities in IIS, Internet Explorer, and MAPI e-mail clients. Nimda moves from host-to-host, client-to-Web server, and Web server-to-client. When Code Red came out, many wondered if it was a proof-of-concept. Nimda makes all these other things look like a dress rehearsal.
This presentation provides an overview of the Nimda Worm, describes how it works, and offers suggested ways in which to protect your sites. URLs are also provided for Internet sites with information and patches.
