What did Robert Hanssen give to Russia?

Robert Hanssen, a former FBI agent, provided valuable classified information to the Soviet Union and later Russia over a period of more than 20 years.

Robert Hanssen’s espionage activities began in the late 1970s and continued until his arrest in 2001. During this time, he passed on a significant amount of sensitive intelligence to the Russian intelligence services (initially the KGB and later the SVR).

The exact details of the information Hanssen provided are not publicly available in their entirety, as much of it remains classified. However, it is known that he compromised numerous FBI operations and investigations, as well as revealed the identities of multiple American intelligence assets.

Hanssen handed over classified documents, operational procedures, technical information, and other intelligence materials that were of great value to Russia.

Some of the types of information Hanssen disclosed include Counterintelligence operations. Hanssen exposed FBI efforts to track Russian spies and operations on US soil, jeopardizing ongoing investigations and compromising the safety of American agents.

Hanssen  also revealed the identities of several valuable double agents working for the United States within the Russian intelligence community, resulting in their capture, imprisonment, and, in some cases, execution.
