Arrest of Ex-German Spy Chief Highlights History of Notorious Double Agents

Germany’s former spy chief, August Hanning, has been arrested on suspicion of passing state secrets to a foreign intelligence service. Hanning, 80, headed up the Federal Intelligence Service, known by its German acronym BND, from 1998 to 2005. A federal prosecutor’s statement said it strongly suspected him of “treasonous espionage, obtaining state secrets, attempted treason” through contact with foreign intelligence services since 2010, while working as a private consultant. He is accused of obtaining around 2,000 sensitive documents from a former bureau chief who has also been arrested.

However, he is not the only high-ranking intelligence officer discovered to have worked for foreign governments over the years. A look back at history reveals several notable cases of high-profile espionage.

1940s to 1960s – Kim Philby and the ‘Cambridge Five’

Kim Philby was a British intelligence officer who secretly spent decades working for the Soviet Union during World War II and the early Cold War years. Recruited by Soviet Intelligence while studying at Cambridge University in the 1930s, he became the most prominent member of the “Cambridge Five” spy ring. During the war, he joined MI6, eventually heading its counter-Soviet division, and was later posted to Washington, DC, gaining access to sensitive information through links to the CIA and FBI. His tip-offs to Soviet handlers scuppered many Western operations, including efforts to overthrow Albania’s communist leader Enver Hoxha.

Philby came under suspicion in 1951 after Guy Burgess and Donald Maclean defected to the Soviet Union. Though formally cleared in 1955, he fled to Russia in 1963 as the net closed in, living with his wife Rufina Pukhova until his death in 1988. He provided state secrets, agent identities, cabinet minutes, and atomic research to the Soviet Union for nearly 20 years, earning a reputation as the most damaging spy in British history. Among those unmasked and subsequently executed were Soviet defector Constantin Volkov and hundreds of anti-communist agents involved in the joint CIA-MI6 Albanian operation.

1970s and 1980s – Oleg Gordievsky

Oleg Gordievsky was a KGB colonel who spied for British intelligence for more than a decade. The son of an NKVD officer, he was recruited by MI6 in the early 1970s following the Prague Spring in Czechoslovakia in 1968 and the building of the Berlin Wall. Stationed in Copenhagen and later London, where he became KGB station chief in 1985, he provided invaluable intelligence regarding KGB fears over NATO’s 1983 Able Archer exercise, helping the West de-escalate tensions.

After being recalled to Moscow in 1985 under suspicion, Gordievsky was interrogated before MI6 executed a daring rescue operation, smuggling him out of Russia in the boot of a car across the Finnish border. Sentenced to death in absentia by Russia, he lived under protection in the UK until his death in 2025.

1980s and 1990s – Robert Hanssen

Robert Hanssen was a high-ranking agent at the US Federal Bureau of Investigation (FBI) who spied for the Soviet Union and Russian intelligence services between 1979 and 2001. After joining the FBI in 1976, he approached Soviet military intelligence in 1979, operating under the alias “Ramon Garcia” using dead drops to exchange classified documents for cash and diamonds.

Hanssen handed over thousands of pages of material, including US nuclear war plans and the identities of Russian officials working for the US, leading to the execution of sources such as Dmitri Polyakov and Valery Marynov. His arrest in February 2001 followed the 1994 capture of Aldrich Ames. Hanssen pleaded guilty to avoid the death penalty and died in prison in 2023.

2000s – Alexander Yuk Ching Ma

Alexander Yuk Ching Ma is a former CIA officer who was caught spying for China. Having worked for the CIA from 1982 to 1989 and become a US citizen in Honolulu, he was approached by officers of China’s Shanghai State Security Bureau in March 2001. In exchange for $50,000, he and a now-deceased former CIA officer provided classified information during a meeting in Hong Kong.

The FBI subsequently hired Ma as a contract linguist to monitor his activities before arresting him in a sting operation. Ma pleaded guilty in May 2024 and is currently serving a 10-year prison sentence.
