No. It is normal.
It is one of the normal accounts put there in a standard install.
It is essentially a root account by another name.
Some things used to like to use it to own their installed stuff but
avoid using root directly.
I don't know if anything really does that any more.
I sometimes use it as a model pw entry when in vipw for
creating new accounts directly to help avoid missing a field.

This has been brought up and answered numerous times in the past.
You might try and search for information on toor account. You
should be able to find something.
