January 2009 is shaping up to be one of the worst months ever as the Cornficker or Downadup worm is said to have infected more than 10 million computers worldwide and could become the biggest botnet network ever according to some experts.
F-Secure reported that nearly nine million computers were compromised on Friday 16th at 2PM GMT, a near four fold increase in 100 hours or so, that's roughly 67700 new PCs turning to Zombies every hour (or 1.625 million per day).
At this rate, the botnet will have doubled in size to reach nearly 20 million by the end of the week, at least two orders of magnitude compared to previous bonets.
There are indications that whoever are behind the attack is about to modify the worm's code to make it more aggressive.
One trick that Cornficker is employing is the use of brute force password attacks to crack open home networks through the use of removable USB drives and other flash memory; this means that even patched PCs could potentially fall prey to the virulent malware.
Here is proof of concept.
This demonstrates one could create a bot net big enough to take down the
