Veil
Veil by Veil-Framework is a tool designed to generate metasploit payloads that bypass common anti-virus solutions.
Veil is current under support by @ChrisTruncer
Veil 3.1, the latest edition uses a more sophisticated way and will now allocate memory with RW permissions, to enable the stager to write shellcode into the allocated memory. After writing the shellcode to the allocated memory, the stager will call VirtualProtect to change the memory permissions from RW to RX. At this point, the stager will continue on to call CreateThread and WaitForSingleObject as normal. Making it even more powerful.
Software Requirements:
The following OSs are officially supported:
- Debian 8+
- Kali Linux Rolling 2018.1+
The following OSs are likely able to run Veil:
- Arch Linux
- BlackArch Linux
- Deepin 15+
- Elementary
- Fedora 22+
- Linux Mint
- Parrot Security
- Ubuntu 15.10+
- Void Linux
Setup
Kali’s Quick Install
apt -y install veil
/usr/share/veil/config/setup.sh --force --silent
Git’s Quick Install
NOTE:
- Installation must be done with superuser privileges. If you are not using the root account (as default with Kali Linux), prepend commands with
sudoor change to the root user before beginning. - Your package manager may be different to
apt. You will also need an X server running, either on the system itself, or on your local system.
sudo apt-get -y install git
git clone https://github.com/Veil-Framework/Veil.git
cd Veil/
./config/setup.sh --force --silent
./config/setup.sh // Setup Files
This file is responsible for installing all the dependences of Veil. This includes all the WINE environment, for the Windows side of things. It will install all the necessary Linux packages and GoLang, as well as Python, Ruby and AutoIT for Windows. In addition, it will also run ./config/update-config.py for your environment.
It includes two optional flags, --force and --silent:
--force ~ If something goes wrong, this will overwrite detecting any previous installs. Useful when there is a setup package update.
--silent ~ This will perform an unattended installation of everything, as it will automate all the steps, so there is no interaction for the user.
This can be ran either by doing: ./Veil.py --setup OR ./config/setup.sh --force.
./config/update-config.py // Regenerating Configuration file
This will generate the output file for /etc/veil/settings.py. Most of the time it will not need to be rebuilt but in some cases you might be prompted to do so (such as a major Veil update).
It is important that you are in the ./config/ directory before executing update-config.py. If you are not, /etc/veil/settings.py will be incorrect and when you launch Veil you will see the following:
Main Menu
0 payloads loaded
Don’t panic. Run either: ./Veil.py --config OR cd ./config/; ./update-config.py.
Py2Exe
NOTE: Using Py2Exe is recommended over PyInstaller (as it has a lower detection rate).
MANUALLY Install on a Windows Computer (as this isn’t done by Veil’s setup):
