What way did the Venona papers justify some of the hysteria of the Red Scare?

The Venona papers, which revealed decrypted Soviet intelligence communications, provided evidence that some American citizens, including government officials, were indeed involved in espionage activities for the Soviet Union. This information lent credence to the fears of communist infiltration and espionage that fueled the Red Scare, suggesting that there were legitimate threats to national security. However, while some individuals were found to be spies, the broader hysteria often led to unfounded accusations and violations of civil liberties, highlighting the tension between genuine security concerns and the overreach of anti-communist paranoia.
