A PHP reverse shell is a script that, when executed on a target web server, initiates an outbound connection back to your machine, providing a command-line interface to the server. This technique is commonly used during penetration testing to gain interactive access after discovering a file upload or code execution vulnerability. 1. Obtain a Reverse Shell Script

A PHP reverse shell is a common technique used in penetration testing to gain interactive command-line access to a remote server. Unlike a standard shell where you connect to the server, a forces the server to initiate an outbound connection to your machine. This is highly effective because most firewalls allow outgoing traffic even if they block incoming connections. Deep Dive: Understanding and Using PHP Reverse Shells 1. How a Reverse Shell Works
