Abstract-- Physical control systems are increasingly controlled by reconfigurable, network-enabled devices to increase flexibility and ease commissioning and maintenance. Such capability creates vulnerabilities. Devices may be remotely reprogrammed by a malicious actor to act in unintended ways, causing physical damage to mechanical equipment, infrastructure, and life and limb. In this paper, past examples of actual damage to cyber- physical systems are shown, threats posed by software-controlled Variable Frequency Drives (VFDs) are analyzed, and a small-scale version of an attack on ubiquitous VFD equipment is demonstrated.

PreventOTPhysDamage: Anticipating and Preventing Catastrophic OT Physical Damage Through System Thinking Analysis

Physical industrial control systems are increasingly controlled by reconfigurable, network-enabled devices to increase flexibility and ease commissioning and maintenance. Such capacity creates vulnerabilities. Devices may be remotely reprogrammed by a malicious actor to act in unintended ways, causing damage to mechanical equipment, infrastructure, and life and limb. In this paper, a few examples of actual damage to cyber-physical systems are shown and a small scale version of an attack on ubiquitous equipment is demonstrated.
