#470 Information Spookyhighway
This week we take a closer look at a few of the downsides of the modern internet, and some of the security and privacy challenges that are becoming increasingly troublesome. Rachelle Saunders speaks with cyber security expert James Lyne about how modern hacking differs from the hacks of old, and how an internet without national boards makes it tricky to police online crime across jurisdictions. And Bethany Brookshire speaks with David Garcia, a computer scientist at the Complexity Science Hub and the Medical University of Vienna, about the recent Cambridge Analytica scandal, and how social media platforms put a wrench...
