  • Apr 29, 2011 · This means an attacker can watch all the TCP based connection made on the local network, and possibly "hijack" the session. After the connection is made, the attacker can watch the entire session (for a telnet session, this means the attacker sees the "playback" of the entire session. This is like actually seeing the telnet window).

    Finally, Nmap tells the user how difficult tcp sequence number prediction is for the remote host. This information can be used to target hosts that have a high potential for session hijacking. Such measures might be employed when a remote system has no vulnerable services running, or when it is shielded behind a firewall.
