Nimda - New Email and Web Worm
WinInfo | at | by Mike
Federal authorities have described a new Internet-based worm that is targeting Windows machines through email and Web servers as being more disruptive than this summer's "Code Red" worm. The worm, dubbed "Nimda" ("admin" spelled backwards), likely originated in China and is unique because it attacks a number of known flaws in various versions of Windows. Viewers can obtain the worm visiting tainted Web sites, and it can be sent via an email attachment called "readme.exe". Security experts say that it doesn't delete any data, but it's very hard to remove, quite easy to spread, and can be used in Denial of Service (DoS) attacks.
