PHANTOM EVASION 3.0

Phantom-Evasion is an antivirus evasion tool written in python (both compatible with python and python3) capable to generate (almost) fully undetectable executable even with the most common x86 msfvenom payload.

The following OSs officialy support automatic setup:

  1. Kali Linux
  2. Parrot Security

The following OSs likely support automatic setup but require manual installation of metasploit-framework:

  1. OSX (tested on Catalina)
  2. Ubuntu
  3. Linux Mint
  4. Elementary
  5. Deepin
  6. other Debian distro
  7. Centos
  8. Fedora
  9. Blackarch

The following OSs require manual setup:

  1. Windows 10

Simply git clone or download and unzip Phantom-Evasion folder

Setup:

Automatic setup, open a terminal and execute:

python3 phantom-evasion.py --setup

or:

chmod +x ./phantom-evasion.py

./phantom-evasion.py --setup

or start phantom-evasion in interactive mode and select option 7

Dependencies (only for manual setup)

  1. metasploit-framework
  2. mingw-w64 (cygwin on windows)
  3. gcc-multilib
  4. apktool
  5. apksigner
  6. strip
  7. osslsigncode

CMDLINE/INTERACTIVE:

  1. Launch phantom-evasion in interactive mode:
python3 phantom-evasion.py

or:

./phantom-evasion.py
  1. Otherwise to see cmdline mode options:
python3 phantom-evasion.py --help

or:

./phantom-evasion.py --help
