Tom Uren and Amberleigh Jack talk about Microsoft CEO Satya Nadella’s messaging around personnel changes at the top of its security organisation. These signal a focus on selling security products rather than on making secure products.

They also discuss Expedition Cloud, a Chinese cyber range that replicated the critical infrastructure of neighbouring countries, apparently to develop and fine-tune cyber disruption operations.

Finally, they talk about what we’ve learnt about the role of cyber operations in the US bombing of Iranian nuclear facilities. It was far bigger than we previously thought.
