FBI career and first espionage activities (1976–1981) Upon becoming a special agent on January 12, 1976, Hanssen was transferred to the FBI's field office in
Gary, Indiana. In 1978, he and his growing family of three (eventually six) children relocated to NYC when the bureau transferred him to its field office there. The next year, Hanssen was transferred to
counterintelligence and given the task of compiling a database of Soviet intelligence for the FBI. During his first espionage cycle, Hanssen provided a significant amount of information to the GRU, including details of the FBI's bugging activities and lists of suspected Soviet intelligence agents. His most important leak was the betrayal of
Dmitri Polyakov, a
CIA informant who passed enormous amounts of information to U.S. intelligence while rising to the rank of general in the
Soviet Army. Following a second betrayal by CIA
mole Aldrich Ames in 1985, Polyakov was arrested in 1986 and executed in 1988. Ames was officially blamed for giving Polyakov's name to the Soviets, while Hanssen's attempt was not revealed until after his 2001 capture.
FBI counterintelligence unit, further espionage activities (1985–1991) used by Hanssen, including on the day of his arrest. In 1981, Hanssen was transferred to
FBI HQ in D.C., and relocated his family to the suburb of
Vienna, Virginia. His new job in the FBI's budget office gave him access to information involving many different FBI operations. This included all the FBI activities related to
wiretapping and
electronic surveillance, which were Hanssen's responsibility. He became known in the FBI as an expert on computers. Three years later, Hanssen transferred to the FBI's Soviet analytical unit, responsible for studying, identifying, and capturing Soviet spies and intelligence operatives in the United States. Hanssen's section evaluated Soviet agents who volunteered to provide intelligence to determine whether they were genuine or
re-doubled agents. In 1985, Hanssen was again transferred to the FBI's field office in NYC, where he continued to work in counterintelligence against the Soviets. After the transfer, while on a business visit back to Washington, he resumed his espionage career. On October 1, 1985, Hanssen sent an anonymous letter to the
KGB offering his services and asking for $100,000 in cash, . In the letter, he gave the names of three KGB agents secretly working for the FBI:
Boris Yuzhin,
Valery Martinov, and
Sergei Motorin. Although Hanssen was unaware, Ames had already exposed all three agents earlier that year. Yuzhin had returned to Moscow in 1982 and had been subject to an intensive investigation by the KGB because he had lost a concealed camera in the Soviet consulate in San Francisco, but he was not arrested until he was exposed by Ames and Hanssen. Martynov and Motorin were recalled to Moscow, where they were arrested, charged, tried, and convicted of espionage against the Soviet government. Martynov and Motorin were executed via gunshot to the back of the head; Yuzhin was imprisoned for six years before he was released by a general amnesty granted to political prisoners and he subsequently immigrated to the U.S. Because the FBI blamed Ames for the leak, Hanssen was neither suspected nor investigated. The October 1 letter began a long, active espionage period for Hanssen. Hanssen was recalled to D.C., yet again in 1987. He was tasked with studying all known and rumored penetrations of the FBI to find the man who had betrayed Martynov and Motorin; in effect, he was charged with searching for himself. Hanssen ensured that he did not reveal himself in his study, but he also gave the entire study—including the list of all Soviets who had contacted the FBI about FBI moles—to the KGB in 1988. That same year, Hanssen, according to a government report, committed a "serious security breach" by revealing secret information to a Soviet
defector during a debriefing. The agents working for him reported this breach to a supervisor, but no action was taken. Later that year, Hanssen gave the KGB extensive information about U.S. planning for
MASINT, a general term for intelligence collected through various electronic means, such as
radar, spy satellites, and signal intercepts. When the Soviets began construction on a
new embassy in 1977, the FBI dug a tunnel beneath their decoding room. The FBI planned to use it for eavesdropping, but never did for fear of being caught. Hanssen disclosed this information to the Soviets in September 1989 and received a $55,000 payment the next month, . On two occasions, Hanssen gave the Soviets a complete list of American
double agents. In 1990, Hanssen's brother-in-law, Mark Wauck, an FBI employee, recommended that the FBI investigate Hanssen for espionage after his sister, Hanssen's wife, told him that their sister, Jeanne Beglis, had found a pile of money on a dresser in the Hanssens' house. Bonnie previously told her brother that Hanssen once talked about retiring in Poland, then part of the
Eastern Bloc. Wauck also knew that the FBI was hunting for a mole and spoke with his supervisor, who took no action.
Later FBI career, continued espionage activities (1992–2001) When the
USSR dissolved in December 1991, Hanssen, possibly worried that he could be exposed amid the ensuing political upheaval, ceased communications with his handlers for about 10 months. The following year, after the
Russian Federation assumed control of the defunct Soviet spy agencies, Hanssen made a risky approach to the
GRU. He went to the Russian embassy in person and physically approached a GRU officer in the parking garage. Hanssen, carrying a package of documents, identified himself by his Soviet
code name, "Ramon Garcia", and described himself as a "disaffected FBI agent" who was offering his services as a spy. The Russian officer, who did not recognize the code name, drove away. The Russians then filed an official protest with the
DOS, believing Hanssen to be a triple agent. Despite having shown his face, disclosed his code name, and revealed his FBI affiliation, Hanssen escaped arrest when the FBI's investigation into the incident did not advance. Hanssen continued to take risks in 1993 when he hacked into the computer of a fellow FBI agent, Ray Mislock, printed a classified document from Mislock's computer, and took it to Mislock, saying, "You didn't believe me that the system was insecure." Hanssen's superiors began an investigation into his activities. In the end, officials believed his claim that he was merely demonstrating flaws in the FBI's security system. Mislock has since theorized that Hanssen probably went onto his computer to see if his superiors were investigating him for espionage and invented the document story to cover his tracks. In 1994, Hanssen expressed interest in a transfer to the new
NCSC, which coordinated counterintelligence activities. When told that he would have to take a
lie detector test to join, Hanssen changed his mind. Three years later, convicted FBI mole
Earl Edwin Pitts told the FBI that he suspected Hanssen due to the Mislock incident. Pitts was the second FBI agent to mention Hanssen by name as a possible mole, but superiors were still unconvinced, and no action was taken.
IT personnel from the NSD's IIS Unit were sent to investigate Hanssen's desktop computer after a reported failure. NSD chief Johnnie Sullivan ordered the computer impounded after it seemed to have been tampered with. A digital investigation found that an attempted hack had occurred using a
password cracking program installed by Hanssen, which triggered a security alert and a lockup. After the FBI CART Unit confirmed the attempted hack, Sullivan filed a report with OPR requesting a further investigation. Hanssen claimed he was trying to connect a color printer to his computer, but needed the password cracker to bypass the administrative password. The FBI believed his story, and Hanssen was merely warned. While the investigation into his computer was underway, Hanssen searched the FBI's internal case records to see whether he was under investigation. He was indiscreet enough to type his name into FBI search engines. Finding nothing, Hanssen decided to resume his spy career after eight years without contact with the Russians. He established contact with the
SVR (a successor to the KGB) in autumn 1999. Hanssen continued to perform incriminating searches of FBI files for his name and address. == Investigation and arrest ==
