Conficker seems to have slowly started activity. According to Symantec researchers, the worm's authors have started installing a second virus, called Waledac, onto some infected computers, reports redOrbit. Waldec turns the PC into a botnet that sends out spam. In addition, notes myfoxdc.com, a third virus carried by Conficker prompts infected PC owners to buy a bogus antivirus program called Spyware Protect 2009 for $49.95. If users take the bait, their credit card information is stolen.
Originally, it was thought that Conficker would become active on April Fool's Day, but the media hype proved to be just that. A few days later, there appeared to be some activity as the worm began contacting infected computers via a binary file over peer-to-peer.
Vincent Weafer, a vice president with Symantec Security Response, warns that infection from Conficker will be "long-term, slowly changing," which means the economic impact could be very high. In fact, according to ZDNet, the Cyber Secure Institute believes that the economic loss due to the Conficker worm could be as high as $9.1 billion.
