The tried and true method of going after the IRC command and control server for a botnet is coming to a slow death. Where there is money there is ingenuity, and when you combine that with organized crime, it all happens quickly. Much as is stated in the article, having an IRC server brought down is, surprisingly enough, not a simple task even when it is clearly involved in botnet activity. You can now imagine compounding that problem by the thousands as you will now have to go after the individually infected hosts. There really has to be a simpler way. For me this is simple. Get the ISP’s involved. Ratchet up the penalties levied against people convicted of controlling botnets. I’d say it’s a good start.
