I gave a talk at a local hacker meetup this past weekend.  My talk was a combination of LLMNR and NetBIOS Poisoning, Responder, and the Responder Monitor decoy in Mazerunner.  A lot of what is in the presentation is already posted here but I think it would be helpful to have an aggregate, in the form of a presentation, to put it all together.  The key points are:  What is Responder?  How the attack works.  Possible defensive measures.  Reality.  And finally, How Mazerunner can help identify the attacker.
