** [Crpt] Utility Manager exploit v2.666 modified by kralor [Crpt] **
|
|
*******************************************************************************************
|
|
** 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.. **
