Attack Payloads with applications to Botnets

Crypto and standard attack techniques can be combined with payload engineering to create dangerous botnet attacks that leverage the size of the botnet, or in any case give the attacker some advantage, and include some stealth functionalities. Examples of this include a technique for automatically shopping on e-tailers sites keeping private the products sought and the expected prices, a worm that will spreads over the internet but performs a special operation on computers with a property which is kept private, et cetera.
