Attackers hope getting administrator privileges always. If they had get it, they can do anything. Therefore, they try to get administrator privileges in various ways, such as account stealing, privilege escalation, UAC bypass.
I have found one way to escalate privileges to administrator without using vulnerability. I hope you to see the demo, understand the mechanism, and prepare against the attacks.
