UAV

A drone; a physical reconnaissance and delivery threat.

A UAV, commonly called a drone, can serve as a physical reconnaissance platform or a delivery mechanism for rogue devices, and it bypasses ground based perimeter controls. Attackers may use one to photograph facilities, capture wireless signals from above, or drop a malicious access point onto a roof. Defenses fall under physical security and include airspace monitoring and counter drone measures. It illustrates that the threat surface extends beyond fences and locked doors.
