It’s 4 AM at Spika, a small cramped Internet Café in downtown Prague. A young student is sipping a coffee in the back corner of the café. He enters a blog and posts a photograph with the caption Zhelayu vsego khoroshego or (wishing you the best). At precisely 6 A.M. dozens of Botnet operators visit the same blog page automatically retrieving the photograph posted as instructed.
