IBM’s Tom Cross presented a white paper at Black Hat DC 2010 titled Exploiting Lawful Intercept to Wiretap the Internet. The paper describes Cisco’s implementation of CALEA for law enforcement-directed wiretaps. It’s a great piece of work which I wish I had read earlier. I got more out of taking 20 minutes to read Tom’s 15 pages of material than I could have trying to make sense out of his 41 slides. In this post I’d like to show how Tom did use PowerPoint well so that I keep these ideas in mind when I need to brief audiences.”]
