Introducing X: Playing Tricks with ICMP

Presented at DEF CON 9 (2001), July 14, 2001, noon (50 minutes)

During my research with the �ICMP Usage In Scanning� project, I have discovered some new active and passive operating system fingerprinting methods using the ICMP protocol. Methods that are simple, and efficient.

The active operating system fingerprinting methods were not correlated into a certain logic. A logic that would allow us to have the ability to use any available method in order to, wisely, actively fingerprint an operating system.

In this talk I will be releasing a new active operating system fingerprinting tool using the active OS fingerprinting methods with the ICMP protocol I have discovered. I will be explaining the tool�s inner works and the various active OS fingerprinting methods with ICMP implemented and used with the tool.

The tool�s limitations, ways to detect its usage, and how to defend our selves from its abilities will also be discussed. Future plans and enhancements, which include a different approach to OS detection, will be presented as well.
