Jack Koziol of the InfoSec Institute (infosecinstitute.com) gave a presentation at ChicagoCon 2008 titled "Understanding Heap Overflow Exploits". A PDF of the slide deck can be found on ChicagoCon.com or EthicalHacker.net.
The following table details Koziol's slides that were taken from other sources, making up 76% of the material (100% if you ignore non-content slides). Given the single source used, it is clear that Koziol willfully infringed copyright and plagiarized most of the material. Given the list of ISI clients he includes on the ISI web site and other presentations, it is disturbing that so many agencies and companies have paid them for services.
Several slides appear to be written by Koziol, but are merely title (#1), biography (#2), introductory (#3), brief history of exploit writing (#4), and closing (#21) slides. Ignoring these slides, 100% of the content of the presentation is taken from a single source without attribution.

A reader also points us to the accompanying audio track. Around 8:30, Koziol does not appear to realize that the "486 architecture" is still present in modern x86 processors, among other statements that suggest a level of unfamiliarity with the material.
