Siegeware: When Criminals Take Over Your Smart Building

A cybersecurity researcher presents a scenario for the employment of “siegeware,” whereby an adversary holds a building for ransom by hacking into the software that controls its functionality, including room temperature, door locks, and alarms. According to the researcher, this is not an imaginary scenario, as he claims to have met someone who was the victim of a siegeware attack. When the person’s company refused to pay the attackers, its use of the targeted building was disrupted. And in his further investigations, the researcher discovered other similar incidents involving siegeware.
