The worlds media has slapped the label of Drone onto any Quadrocopter, Octocopter or any other modern platform without actually investigating the differences between commercial and military models. Drone technology has just as many undisclosed security issues as any other Internet of Things (IoT) device.

Governments and Aviation Authorities have attempted to instigate to curb the menace only to see a threat evolving which poses a danger to the drones themselves.”]
