I have VPS based on Linux and this server is compromised at the root level by malware known as ShellBot. This malware is known to cause errors when running the "crontab" command but can potentially cause many other problems including not being able to start certain services.
The presence of the following file is an indication of this malware.

I think this probably occurred as a result of the recent Exim vulnerability CVE-2019-10149, since the GID on the file is 'mail'.
The reason this server was exploited is because cPanel updates were disabled by setting the version to 184.108.40.206 in the cpupdate.conf file:
[root@s148-72-213-141 ~]# grep CPANEL /etc/cpupdate.conf
The only actions that can be considered to reasonably address a root compromised server are to either perform a fresh Operating System and WHM/cPanel installation and restore account backups or to migrate the accounts to a known clean server that hasn't been previously root compromised.
Now what should I do???
Contacting phone support in this instance is probably your best option. As to be transferred to the Hosting Department and they should be able to give you some options.
Once your issue is resolved,
please be sure to come back and click accept for the solution
Hey Thanks man but unfortunately they won't help, I have received different responses from there end like they don't have specialist staff and now that I am not using managed services so I have to change my package for assistance.
See following is the evidence of the malware:
[root@s148-72-213-141 ~]# sha256sum /lib/libgrubd.so

I think Im on my own, it wasn't a wise decision to shift to Godaddy indeed!
