In Episode 3, host and former lead cybersecurity and digital espionage reporter for The New York Times, Nicole Perlroth visits a welding shop in rural Wisconsin where Chinese hackers have set up shop in a dusty, back-office server. Hackers are using the welding shop as staging grounds to attack a staggering range of American businesses, including a major American airline, fast-growing Silicon Valley start-ups, law firms and research labs, in search of capitalism’s crown jewels: Intellectual property.

Nicole revisits a period that cybersecurity experts now call “the most dangerous time in American history”-- a period in which the blueprints to airplanes, stealth fighter jets, turbines, genetically-modified seeds, oil exploration strategies, even the formula for white paint, were smuggled back to China.
