#!/usr/bin/perl
# This is made for trashing cisco 7940 ip phones. kokanin made/discovered this.
# A packetcount of 1000 and a packetdelay of 0.002 sent to port 80 makes my 
# phone reboot - play with the settings and stuff. PRIVATE PRIVATE PRIVATE!!!
# not private anymore. Vulnerable phones are running ver. 7.0(2.0) using the skinny
# protocol - this is not for the SIP firmware.
