The story of a suspected KGB mole who shook the FBI in the 1960s

Readers of this blog will know about the infamous case of James Jesus Angleton, who headed the counterintelligence department of the Central Intelligence Agency from the 1950s to the 1970s, and led the biggest mole hunt in the Agency’s history. David Wise, author of several intelligence-related books, including the best-selling Spy, about FBI double agent Robert Hanssen, writes in a new article that the Federal Bureau of Investigation (FBI) was also shaken by a similar mole hunt, which never became public. In an article published in this month’s Smithsonian Magazine, Wise claims that the probe constituted “the first mole hunt in the history of the FBI” and that it was “one of the most sensitive investigations” in the history of the Bureau. Wise suggests that the mole hunt began in the spring of 1962, when Aleksei Kulak, a 39-year-old Soviet scientific consultant to the United Nations, who was in fact KGB operative, defected to the FBI. He was instructed by his American handlers to operate as an agent-in-place and supplied the FBI for a decade with secret information from the Soviet Union. The FBI gave him the codename FEDORA, also known in Bureau files as “Source 10”. In his article in The Smithsonian, which is based on interviews with no fewer than 30 current and former FBI agents, Wise describes FEDORA as “one of the most important sources the FBI had” at the time. Kulak and another KGB agent, Valentin Lysov, who defected to American intelligence in the mid-1960s, told the FBI that the Soviet Union kept a source inside the FBI, known as “Dick”. But neither defector knew whether Dick was the source’s real name, or whether it was simply a KGB operational codename. The FBI, says Wise, gave the alleged mole the code term UNSUB (“unknown subject”) Dick, and began a massive mole hunt. Read more of this post
