InternetNews.com: FBI, CERT Warn New Worm Spreading Fast

"The Federal Bureau of Investigation and private sector security experts Tuesday warned of a sophisticated new virus dubbed Nimda, which spreads both as a worm exploiting the same vulnerabilities used by the recent Code Red and sadmind/IIS worms, and as an e-mail virus. Experts said the worm could proliferate as widely as Code Red.

The Computer Emergency Response Team Coordination Center (CERT/CC), based at Carnegie-Mellon University, said "User machines that are infected by this virus might see an increase in scanning as the virus tries to compromise IIS servers. Many sites are experiencing high loads of e-mail and network traffic as a result of this activity."

London-based GFI Security Labs said Tuesday afternoon that Nimda replicates quickly and has the ability to spread through e-mail clients even if recipients don't open the attachment, ReadMe.exe, which comes with infected e-mails."
