The Conficker worm has been wreaking havoc on the Internet for several months. A new analysis of Conficker by SRI International shows that the worm s authors have added further code obfuscation and other mechanisms to avoid analysis and removal. The SRI research team said that it appears that as much as 85 percent of the worm’s code was changed in the current version. The result, the SRI authors say, is that if organized into a coordinated offensive weapon, this multimillion-node botnet poses a serious and dire threat to the Internet.
