Alexander Zaporozhsky
Zaporozhsky is a former KGB colonel who, started with the KGB in 1975 followed by the SVR and was responsible for the recruitment of informants in the United States and the Russians believe, ratted out FBI official Robert Hanssen as a double agent working for the Russians. The Associated Press also reports that he is believed to have helped expose Aldrich Ames, the CIA official convicted of passing secrets to the Russians in 1994. Zaporozhsky first began working with the CIA in 1995 and illegally left Russia in 1998 to move to Maryland, according to the Historical Dictionary of International Intelligence. After arriving in the United States, he worked for what the Russians believed to be a CIA front company. In November 2001 — nine months after Hanssen's arrest — Russian agents somehow lured Zaporozhsky back to his homeland, where he was promptly arrested. In 2003, he was sentenced to 18 years in prison. If it's true that Zaporozhsky gave up Hanssen and Ames, then he's one of the most valuable intelligence assets the United States had during the Cold War. Alexander Zaporozhsky (Russian: Александр Иванович Запорожский) is a former Colonel in Russia's SVR.
