Greek Air Force squadron leader Christos Flessas was arrested on suspicion of espionage for China, accused of transmitting top secret military information, including classified NATO documents, to Chinese intelligence using specialized encryption software. He allegedly received tradecraft training in China during an undeclared trip and was recruited through online contact and a NATO conference. Financial incentives of €5,000 to €15,000 per transmission were reportedly offered. Greek authorities were tipped off by the CIA. The case highlights China's ongoing effort to infiltrate Western military and intelligence services and penetrates Greece's military communications infrastructure. Flessas was commanding a battalion training in telecommunications at the time of arrest and had previously served as a NATO information systems evaluator.
