The [[FBI]] first detected Koral in 1941 while surveiling [[Gaik Ovakimian]], whom the FBI did not realize at the time was the head of KGB operations in the United States. The FBI noted Ovakimian meeting several times with Koral, though no espionage could be proved.  Koral was working at the time as a school district maintenance man.

After [[World War II]], in 1947 Koral confessed when confronted by the FBI to being a courier for the KGB from 1939 to 1945.  Koral told the FBI he was paid two thousand dollars to travel to different cities to pick up and deliver small packages and envelopes to different persons, including [[Greg Silvermaster]] and [[Helen Silvermaster]]. In December 1945 Koral was sent to tell Silvermaster “no more visits would be made to him”, at the time of [[Elizabeth Bentley]]'s defection and the Soviet networks were being compromised.  Koral identified [[Semyon Semenov]] as one of his contacts in Soviet intelligence to whom he had delivered materials.
