Installing the WannaCry virus with administrative rights?

Question

System administration

I wanted to clarify, one of the users can install this virus from the mail, if he has lowered rights? Or does this require no rights at all

Answer 1

Not needed. The user is not involved at all in this case.
The attack comes from outside on port 445 on SMB

I just don't know how many "admins" don't know about firewalls.
