cPanel VPS Server Cannot Login as root

I was worried the server was hacked, I was logged in already as root but couldn't login to CPanel or a new SSH session.  I even reset the password from the shell and it did not work still.

The reason is CPanel Hulk, it detected a brute-force attack so it locked down the root account entirely even from the correct password.  According to cPanel the best way around this is to whitelist your IP.

I was aware of CPanel Hulk but didn't know it completely locks an account even if the password is correct from non-offending IPs so this is something to be aware of, someone could potentially create a denial of service against any of your services/accounts just be intentionally bruteforcing them.

The most practical quick way is to just disable cpHulk:
