PageRank and similar ranking algorithms on graphs can be used to detect monitoring attempts in P2P botnets [0] (a botmaster can detect when researchers/law enforcement start monitoring a botnet).
For my master's thesis, I evaluated these algorithms and tried to find ways to prevent detection and came to the conclusion that it is hard if you don't want to deploy about as much sensor nodes as the botnet has active peers. Those algorithms are working really well and are hard do work around.
