Aaron, code-named "Lighthouse," initiated contact with the KGB on November 5, 1981. After a cautious period of mutual testing, the first official encounter took place on January 1, 1982.
The first batch of intelligence Aaron passed on was extremely valuable; the CIA's spy network in Eastern Europe, which had been established for many years, was directly dismantled, and Aaron did not ask for any payment.
In July 1982, Aaron voluntarily provided intelligence to the KGB for the second time, leading to the confirmation that a high-ranking Moscow government official had leaked information to the CIA multiple times. The KGB unearthed a significant mole.
After the second encounter, Aaron's value was undoubtedly confirmed. It was also after this meeting that the KGB offered Aaron a $50,000 reward and Yarebin personally attempted to meet with Aaron in London for the first time.
The first meeting failed, Yarebin was unable to meet Aaron.
