A white hat hacker, with over 30 years of experience as a cybersecurity analyst at a major Silicon Valley company, talks about why he turned his back on black hat hacking for the greater good. He talks about the reality of just how vulnerable our systems really are - from the very real threat of hackers taking the American power grid or medical facilities offline, to how easily accessible our private information is to anyone with WiFi and some time on their hands. Informer is a series where we hear the anonymised confessions and insights of people on the inside of different industries, institutions and events.
