      Komahayown, Inverse Connection Remote Shell
    ------------------------------------------------------------------------

    DETAILS

    Komahayown is a shellcode and client for remote execution of commands
    through an inverse connection (using random ports using the TCP protocol).

    Such an inverse channel is needed because in most cases a Firewall will
    block incoming ports to a server, but will be a lot less restrictive on
    outgoing connections. By creating such an inverse channel, an attacker can
    cause the shellcode to run commands (by sending a simple ICMP packet), and
    send back the response via an unrestricted TCP port.

    A diagram illustrating the mechanism can be viewed by going to:
