The largest (Schwechat) tunnel was from Wyke’s villa in the Schwechat suburb. [2]
Although the operation was considered a success, the details of it were passed on to the KGB in October 1953 by George Blake, a British double agent.[3]
The British monitoring station was disguised as a shop that sold tweed clothing. The operation ended only when Austria regained full sovereignty in 1955.
In 1951, when the American CIA planned a similar operation in Berlin, the British revealed Operation Silver to the Americans and the two countries then jointly ran Operation Gold, an operation to tap into landline communication of the Soviet Army headquarters in Berlin using a tunnel into the Soviet-occupied zone. Blake had also informed the Soviet authorities about Operation Gold in its very beginning, and they "discovered" the tunnel in 1956. The KGB has kept the operation secret to avoid compromising Blake.

The Venona project was a United States counterintelligence program initiated during World War II by the United States Army's Signal Intelligence Service and later absorbed by the National Security Agency (NSA), that ran from February 1, 1943, until October 1, 1980. It was intended to decrypt messages transmitted by the intelligence agencies of the Soviet Union. Initiated when the Soviet Union was an ally of the US, the program continued during the Cold War, when the Soviet Union was considered an enemy.
Operation Keelhaul was a forced repatriation of Soviet citizens and members of the Soviet Army in the West to the Soviet Union after World War II. While forced repatriation focused on Soviet Armed Forces POWs of Germany and Russian Liberation Army members, it included many other people under Allied control. Refoulement, the forced repatriation of people in danger of persecution, is a human rights violation and breach of international law. Thus Operation Keelhaul would have been called a war crime under modern international humanitarian law, especially in regards to the many civilians forced into Soviet work camps, many of whom had never been Soviet citizens, having fled Russia before the end of the Russian Civil War.
John Cairncross was a British civil servant who became an intelligence officer and spy during the Second World War. As a Soviet double agent, he passed to the Soviet Union the raw Tunny decryptions that influenced the Battle of Kursk. He was alleged to be the fifth member of the Cambridge Five. He was also notable as a translator, literary scholar and writer of non-fiction.
Operation Gold was a joint operation conducted by the American Central Intelligence Agency (CIA) and the British MI6 Secret Intelligence Service (SIS) in the 1950s to tap into landline communication of the Soviet Army headquarters in Berlin using a tunnel into the Soviet-occupied zone. This was a much more complex variation of the earlier Operation Silver project in Vienna.

American espionage in Germany was significantly intensified during World War II and the following occupation of Germany. As the Iron Curtain ran through the middle of Germany during the Cold War, divided Germany was an important center of US espionage activities. US intelligence monitored the politics of the Federal Republic of Germany as well as conducting espionage and propaganda against the Eastern Bloc. The CIA and other American intelligence services worked closely with the West German BND, which was a close ally of the Americans. Even after German reunification, a significant American intelligence presence in Germany remained. In 2013, the global surveillance and espionage affair revealed that the American NSA had eavesdropped on and spied on almost all top German politicians, including Chancellor Angela Merkel. The revelations also brought to light that the CIA had informants in politics and the security services of Germany.
