Listen, I’m not going to pretend to understand any of this Conficker business. But the folks over at Gizmodo do, and they’re basically saying the following: hold on to your effin’ hat.
“And here’s why that is deeply, deeply scary. As we explained, Conficker has built a zombie botnet infrastructure by registering hundreds of spam DNS names (askcw.com.ru, and the like), which it then links up and uses as nodes for infected machines to contact for instructions. In its earlier forms, Conficker attempted to register 250 such DNS names per day. But with the third version of the software, the Conficker.c variant which has been floating around for the last month or so, the number of spam DNS takeovers was boosted to 50,000 per day–a number security pros can no longer keep up with.
What the April 1 update did was simple: It provided instructions for linking up with the thousands, perhaps tens of thousands of new nodes registered by Conficker.c over the last few weeks, effectively growing the size of the p2p botnet to a point where it can not be stopped.”
