Andrew Grill returned to BBC Bristol with John Darvall to discuss the news that an OpenAI agent hacked into Australia’s Medicare system, and what it actually means for the average listener’s own devices.
The conversation covered:
• Why the systems you use every day matter more than your personal firewall, AI bots aren’t coming for individual phones and laptops
• Two-factor authentication — the digital equivalent of a second bike lock, a one-time password that changes every 30 seconds
• Password managers — why not knowing your own passwords is a feature, not a problem, and how it cleans up your “digital hygiene”
• The family password — a phrase only your family knows, never shared over WhatsApp or email, for the moment a cloned voice calls in a panic asking for money
Andrew’s line for anyone who thinks this doesn’t apply to them: with voice and video cloning now trivial, “you’re on the radio, I’m on the radio, so they can clone our voice.”
All of these tips are included in chapter 15 of Digitally Curious.
