Eric O'Neill was chosen because he had both computer knowledge and experience in spy hunting, making him one of the few people in the FBI with both skills. Additionally, he had no prior contact with Hanssen, which was crucial for the operation.
Operation Greysuit was designed to catch Robert Hanssen, the most notorious spy in U.S. history, who had been betraying the country for over two decades by handing over critical information to the Russians.
Hanssen exposed three KGB agents working for the U.S. in 1985, leading to their arrest and execution. In 1992, he hacked the FBI's computer system to steal Soviet documents, and in 1999, he signaled his readiness to trade secrets again.
Eric O'Neill worked undercover alongside Hanssen in a cybersecurity division, gathering information to determine if Hanssen was the spy they had been searching for and finding evidence to catch him in the act of espionage.
The turning point came when Hanssen discussed details of the Felix Bloch case, which only someone who had tipped off the Russians could have known. This information was scrutinized by analysts, confirming Hanssen's involvement.
O'Neill used social engineering to get Hanssen to leave his office for a shooting competition, during which he was able to retrieve the Palm Pilot, along with a data card and a floppy disk, from Hanssen's bag.
Hanssen made his final drop to the Russians, providing them with sensitive information, including Eric O'Neill's personal details, suggesting he could be a good recruit for the Russians.
Hanssen pleaded guilty to multiple counts of espionage in March 2002. In exchange for avoiding the death penalty, he agreed to cooperate fully with the FBI and provide all information about his espionage activities.
Working with Hanssen provided O'Neill with a masterclass in espionage, teaching him valuable lessons in counterintelligence and spy hunting, which significantly enhanced his skills and career.
In this classic True Spies episode, Eric O'Neill describes the hunt for the infamous FBI mole Robert Hanssen.
This entire operation hinges around Eric needing to get Hanssen into a hire car so his own car can be searched for evidence of his betrayal... but the hire car isn’t there.
