Olson, who served more than 30 years overseas, had been intercepting sensitive Russian information that was being sent over microwave transmissions.
For this series, Eamon Javers spent nearly a year investigating a criminal network and exploring how wealthy Russian hackers stole millions from U.S. investors.
Javers interviewed FBI agents, prosecutors — and even spies like Olson — to reveal the shocking details of a massive criminal enterprise.
Javers asked Olson what it feels like to go on such a mission, something he called "Mission Impossible stuff."
"It's humbling because you have this sense that your country put that much trust in you to carry out that mission," Olson said.
