Aleksey Kulak

Aleksey Isidorovich Kulak, code name FEDORA, was a KGB Colonel who offered his services to the FBI and CIA between 1962 and 1977. Kulak's assertion that there was a KGB mole within the FBI led to a decades-long mole hunt that seriously disrupted the agency. Kulak's information was taken seriously by American intelligence, but some have claimed that he was a KGB double agent meant to sow chaos within the FBI. Prior to his work in intelligence, Kulak was decorated as a Hero of the Soviet Union for his heroism as a Red Army officer on the Eastern Front. He was posthumously stripped of his awards and rank in 1990, five years after Aldrich Ames ostensibly revealed Kulak's betrayal.
