Harry Magdoff was accused by a number of authors as having been complicit in Soviet espionage activity during his time in US government. He was accused of passing information to Soviet intelligence networks in the United States, primarily through what the FBI called the "Perlo Group."

Other authors have taken issue with some of the broader interpretations of such materials which implicate many Americans in espionage for the Soviet Union, and the allegation that Harry Magdoff was an information source for the Soviets is disputed by several academics and historians asserting that Magdoff probably had no malicious intentions and committed no crimes.
