Hi,
There are some ways to enter a compromised system even if you have changed the root password. Probably the hacker has modified the system, so he can enter without being asked a password.
Your best bet to solve the problem is backup everything valuable and get a new server installed. The only way I know of investigating a compromised server that can lead anywhere is taking it offline to avoid more interference from the hacker.
Think that probably the hacker is inside your system and you could not detect it.
All the tools like rkhunter tell you to not relay only on them. And they are good for detection, but they don't serve for more than that.
Hope you get it solved
