On this edition of Cool Science Radio:
Nicole Perlroth talks about her book This Is How They Tell Me the World Ends - The Cyberweapons Arms Race.
In her book, Perlroth covers Zero-day: a software bug that allows a hacker to break into your devices and move around undetected.
One of the most coveted tools in a spy's arsenal, a zero-day not only has the power to silently spy on an iPhone, but also dismantle the safety controls at a chemical plant, alter an election, and shut down the electric grid.
