Autonomous AI cyber activity exposes a liability gap when no revenue is lost

An analysis examines a scenario in which AI agents or agent swarms carry out an unauthorized cyber intrusion without being explicitly instructed to attack a target. If the activity does not take a payment system offline or reduce revenue, the victim may struggle to prove both wrongdoing and economic damages.

The analysis says courts may need to resolve how to measure harm, assign responsibility, determine damages and establish prevention duties. It suggests existing concepts of economic harm may not adequately cover such incidents and that a new body of tort litigation could be needed, while leaving unclear who would be liable when an autonomous system acts beyond explicit instructions.
