Rkhunter 扫描问题

Rkhunter 扫描问题

我的 rkhunter 扫描有一些误报。然而我今天做了扫描,这些结果确实让我有点担心,我现在有 8 个警告。我将发布我不确定的警告。

 /usr/sbin/runlevel                                       [ Warning 
 /usr/bin/sudo                                            [ Warning 
  /usr/bin/systemd                                         [ Warning ]
  /usr/bin/systemctl                                       [ Warning ]
 /usr/lib/systemd/systemd                                 [ Warning ]

这些是出现的新警告。我查看了日志并发现了这一点。

我真的需要这方面的帮助来查明这是否是误报。 Systemd 确实与其他警告一起引起了我的关注。谢谢。

更新

一位用户告诉我查看最近的更新,我记得我确实做了一些 linux 希望我在过去 2 天做的更新,我在更新历史中发现了一些行 libsystemd0、systemd-coredump、libnss-systemd、systemd、libpam- systemd 和其他更新。看到所有这些涉及 systemd 的更新肯定是误报的迹象。在这些扫描之后,我需要更多地查看我的更新历史记录。我要查看 rkhunter 中的手册页,将每个警告恢复为 OK。它解决了。

答案1

当系统使用apt-get或进行更新时通常会出现这种情况apt。使用以下任一方法更新 rkhunter 文件属性数据库后再次尝试扫描:

sudo rkhunter --propupd

或者,

sudo rkhunter --update --propupd
