    Hi all, 
    
    We posted the following description of the recent Nimda worm, which includes a few details I did not see on other posts: 
    
    "This new worm took everyone by surprise. It is one of the first few to infect both client and server computers, making it highly effective in spreading fast, and almost automatically, without the need for user intervention. It makes use of 2 security vulnerabilities in Microsoft products, the IIS Unicode Vulnerability, as well as another vulnerability in Internet Explorer and Windows Media Player 6.4 (which is included with Windows 2000). This worm also makes use of hosts previously infected by Code-Red II as well as infection through the NETBIOS protocol."
