Cyber insurers including MSIG, QBE, and Beazley are now revising their underwriting frameworks to account for a category of risk that barely existed a few years ago: autonomous AI agents that act unpredictably, independently, and sometimes destructively. No damages have been reported from the disclosed incidents.
