You know the cyberattack is bad when radiation monitors at the Chernobyl nuclear plant have to switch to manual. Just weeks after another worldwide attack that shut down hospitals in Britain, chaos strikes again. Is it down to the carelessness of intelligence services, software makers or customers too lazy to install the latest security updates? But this goes beyond the so-called "Ransomware" viruses dispersed by criminals. It's about just how vulnerable we've become in the digital age. Produced by François PICARD, Yi SONG and Theodora LOULOUDIS.
