XProbe, The Year After

Presented at DEF CON 10 (2002), Aug. 2, 2002, 11 a.m. (50 minutes).

Xprobe, written and maintained by Fyodor Yarochkin & Ofir Arkin, is an active operating system fingerprinting tool based on Ofir Arkin's "ICMP Usage in Scanning" research project (http://www.sys-security.com). Last year at the Blackhat briefings, July 2001, the first generation of Xprobe was released. The tool's first generation (Xprobe v0.0.1) relies on a hard coded static-based logic tree. Although it has a lot of advantages (1-4 packets only, accurate, fast, efficient, etc.) the tool suffers from a major drawback - its logic is static. At Defcon 10 we will be releasing Xprobe2, a complete re-written active operating system fingerprinting tool with a different approach to operating system fingerprinting. Xprobe2 rely on fuzzy signature matching, probabilistic guesses, multiple matches simultaneously, and a signature database. As with the previous year - Don't miss the demonstration!
