WordPress网站被黑了,我尝试了一切

几个星期后,我的WordPress网站被黑了。随机地,黑客修改某些文件的内容,以包含发送数千封垃圾邮件的恶意代码。

我尝试了一切,包括:

  • 更新WordPress
  • 更新所有插件
  • 更新所有外部插件(Revolution Slider,Visual Composer等)
  • 删除所有默认主题和插件,例如Twenty Sixteen,Akismet等,以确保他们不会'有任何恶意代码

我已经安装了WordFence并对两个被黑客攻击的安装启用了全面保护。它会在恶意代码出现时通知我,但我无法找到问题的根源。每次我解决问题,几天后代码出现在其他文件中。

同样重要的是,修改后的文件不具有" Last modified"改性。所以他们以某种方式修改文件而不改变" Last modified"日期戳。

另请注意,文件不会通过FTP或任何其他方法修改,因为除了我之外没有其他任何人登录FTP / cPanel / ssh。

恶意代码是
