I am pleased to announce the immediate availability of the current development code of Xprobe2. Xprobe2 is an 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. The tool's release is accompanied by a white paper explaining our fuzzy approach to operating system fingerprinting and the various problems facing other remote active operating system fingerprinting tools available today, which we have tried to remedy. The current development code is available from: http://www.sys-security.com/archive/tools/xprobe2/xprobe2-current-devel. tar.gz The White Paper is available from: http://www.sys-security.com/archive/papers/Xprobe2.pdf Yours Ofir Arkin [ofir@sys-security.com] Founder The Sys-Security Group http://www.sys-security.com PGP CC2C BE53 12C6 C9F2 87B1 B8C6 0DFA CF2D D360 43FA
