Black Hat and Defcon 2008 Presentation Video and Slides
Summary
The Nmap Security Scanner was built to
efficiently scan large networks, but Nmap's
author Fyodor took this to a
new level by scanning millions of Internet hosts during the Summer of
2008 as part of the Worldscan project. In this presentation given at
the Black Hat Briefings and Defcon (August 2008), he presents the most
interesting findings and empirical statistics from these scans, along
with practical advice for improving your own scan performance. An
overview of new Nmap features is also provided, including
the Nmap Scripting
Engine, Zenmap UI,
new performance options, Ncat, and Ndiff. Most of these features are now
available in Nmap 4.75 and later
(download
page, Changelog).
