From the New York Times article, Vast Spy System Loots Computers in 103 Countries, by John Markoff

Intelligence analysts say many governments, including those of China, Russia and the United States, and other parties use sophisticated computer programs to covertly gather information.

The electronic spy game has had at least some real-world impact, they said. For example, they said, after an e-mail invitation was sent by the Dalai Lama’s office to a foreign diplomat, the Chinese government made a call to the diplomat discouraging a visit. And a woman working for a group making Internet contacts between Tibetan exiles and Chinese citizens was stopped by Chinese intelligence officers on her way back to Tibet, shown transcripts of her online conversations and warned to stop her political activities.
