I’ve also noticed I don’t really find much malware in the wild, at least nothing targeting you’re typical PC user. Maybe I’ll find some boring, barely obfuscated adware, but of it seems to target larger, enterprise organization, which I suppose also makes sense. There was a write up a few days ago about an exploit targeting MS Word that was at least mildly more interesting than most of the stuff I hear about now.
Maybe the attack is already completely done, and they're just leaving the C&C servers and the rest of the botnet up to avoid leaking "The C&C servers went offline at X time" as a piece of information.
