zombie machines

Microsoft was granted a recommendation by a federal magistrate judge to size 276 internet addresses used to control “Waledac,” a massive botnet that the software company has been working to bring down. The recommendation by Magistrate Judge John F. Anderson of the US District Court for Eastern Virginia is a victory in Microsoft's experimental campaign to wrest control of one of the net's biggest menaces.

Last year the Kraken botnet which was considered as the single biggest botnet zombie network, was dismantled. But the new data show that the network seems to be resurrecting. A security researcher reports that the reborn scheme is exploiting about 320,000 PC machines worldwide.
