Cyber attacks can feel a layer detached from the real world. Yes, businesses frequently see IP stolen, get frozen out of systems, or have data wiped by malicious actors. But if you haven’t got your finger on the pulse, cyber attacks can also fail to register in your day to day.

But there are instances where cyber attacks come crashing into the lives of everyday people, and become impossible to ignore: when attackers go after critical infrastructure and operational technology. Breaches and malware attacks at power and water plants, against core supply chain organizations, or against transport networks can all cause catastrophic damage, enormous financial losses – and even lead to deaths.

In this episode, Rory speaks with Magpie Graham, technical director of intel and services at Dragos, to discuss attacks on operational technology, critical infrastructure, and the future of large-scale cyber attacks.
