Hi
I have an issue with the root access of my server. I think it’s been compromised and now I can no longer SSH my server. I am not sure how to investigate and resolve this issue. Any suggestions are highly welcome.
Many thanks in advanced
Regards,

First think you need to do is get access back to the SSH. Almost all providers provide virtual console attribute you may use in emergency cases to get access to your server using SSH. When you do regain your access to the server change the root password and SSH port. Then you can check your log files for further investigations.

Another possibility would be to boot to recovery, then mount the disks and check the logs. You need to make a backup first (if you don’t already have one) and then reinstall.

Try restarting the server in the rescue mode and then change the root password. This will get you access to shh . So now you can reboot and limit access to shh to your IP only. Then you can check your log files.
