Greg coordinated the primary field-based research for the GhostNet and the ShadowNet investigations in the Dalai Lama’s Office and the Tibetan Government-in-Exile in Dharamsala, India, where he worked with a team that uncovered global cyber espionage botnets operating out of China, and penetrating the United Nations, NATO, governments, diplomatic missions, and civil society computers all over the world.
