Like passwords, from infected computers. Ferguson said he believes Eastern Europeans are behind the Waledac worm. He suspects they created the Storm botnet to try different payloads and business models and that Waledac resulted from that. Ferguson speculates that they may be putting their lessons learned from earlier efforts into practice with Conficker. "There is empirical evidence that these guys are a for-hire, for-profit criminal operation on the Internet and that Conficker is nothing more than part of that organization's best efforts to monetize their efforts on the Internet," Ferguson said. Vincent Weafer, vice president of Symantec Security Response, confirmed the Waledac connection with Conficker, but wouldn't speculate on who exactly might be spreading the worms. The fact that Conficker now downloads a Waledac file "reconfirms our belief that ultimately this is a large botnet designed to make money," he said. "It's the first example of how these guys are trying to leverage this botnet for profit."As for the May 3 expiration date in the latest Conficker code, Weafer said it appears to be trying to shut down code related to the first variant of Conficker, Conficker.A, which generated more noise on the Internet than later versions did.Symantec researchers are calling the latest Conficker code that is circulating a new variant of the worm and have dubbed it Downadup.E, with Downadup being another name for Conficker. The worm spreads via a hole in Windows that Microsoft patched in October, as well as through removable storage devices and network shares with weak passwords. The worm disables security software and blocks access to security Web sites. To check if your computer is infected you can use this Conficker Eye Chart or this site at the University of Bonn.

RE: Best Practice for cleaning downadup on winsvr2003 Posted May 22, 2012 11:26 AM Hi,W32.Downadup, also known as Conficker by some news agencies and antivirus vendors, is an extremely interesting piece of malicious code and one of the most prolific worms in recent years. It has an extremely large infection base – estimated to be upwards of 3 million computers - that have the potential to do a lot of damage.This is largely attributed to the fact that it is capable of exploiting computers that are running unpatched Windows XP SP2 and Windows 2003 SP1 systems. Other worms released over the past few years have largely targeted older system versions, which have an ever decreasing distributionCheck Symantec notes & run removal tool. 5.
