This is a story of VoIP security, a disgruntled employee and the trouble that can be caused in an unsecured environment. The presentation is done in a minimalist style popularized by Professor Lawrence Lessig. The 248 slides were presented in about 15 minutes at ClueCon 2009 in Chicago on August 5, 2009. A video recording will be made available and an update will be posted here. Do note that I did give an older version of this talk at ETel 2007 as "The Black Bag Security Review".]]>
