  ISH Detection Tool
------------------------------------------------------------------------

DETAILS

ISH Detect is a tool that is able to detect the presence (off the wire) of
the product of ICMP Shell.
<http://www.securiteam.com/tools/5PP0M0K60O.html> ICMP Shell is a program
written in C for the UNIX environment that allows an administrator to
access their computer remotely via ICMP packets.

ICMP Shell uses an identifier of 16 bits in each ICMP packet to
communicate between the client and the server. ISH Detect tries to detect
the presence of the ICMP Shell by sending ICMP packets while varying the
identifier from 0 to 65535 and watching for the response. If the server
receives a package with a bad identifier, it will not answer (unlike
normal operating system behavior).
