How to Generate a PHP Backdoor using Weevely – Kali Linux

Weevely is a web shell designed for post-exploitation purposes that can be extended over the network at runtime.

Upload weevely PHP agent to a target web server to get remote shell access to it. It has more than 30 modules to assist administrative tasks, maintain access, provide situational awareness, elevate privileges, and spread into the target network.

Read the Install page to install weevely and its dependencies.

Read the Getting Started page to generate an agent and connect to it.

Browse the Wiki to read examples and use cases.

Features

  • Shell access to the target
  • SQL console pivoting on the target
  • HTTP proxy pivoting on the target
  • Upload and download files
  • Spawn reverse and direct TCP shells
  • Audit remote target security
  • Run Meterpreter payloads
  • Port scan pivoting on target
  • Mount the remote filesystem
  • Bruteforce SQL accounts pivoting on the target

Agent

The agent is a small, polymorphic PHP script hardly detected by AV and the communication protocol is obfuscated within HTTP requests.
