Worm propagation strategies in an IPv6 Internet

I like this paper, not only because it dispells a myth but it's also the same line of arguments I've been using for years. Thanks to Ismael for the tip. 

We discuss a number of strategies worms could use in an IPv6-based Internet to find new targets. We separate these into two categories, wide-area and local-area searches, somewhat mirroring the IPv6 address architecture. We argue that worms will use different types of information sources to first determine existing networks and establish a presence there, and then spread locally inside an organization. We hope to illustrate that simple reliance on the IPv6 address space for protection against scanning worms is not a wise defensive strategy, and we suggest areas where research could assist in detecting and limiting future worm propagation.
