So far it has spilled military secrets and the private phone numbers of TV stars, airport security access codes and elementary school children's grades.

The culprit is a digital worm that infects computers using the file-sharing Winny software, a Japanese computer program that, like the infamous Napster, was designed to allow people to easily swap music and movie files
Perhaps most embarrassing have been the leaks from Japan's Self-Defense Forces, including data on surface-to-air missile tests and details of "Battle Scenario Training" for a simulated crisis on a transparently code-named "K Peninsula."

I may be wrong, but I don't think anything quite like this has hit filesharing programs used in the western world. Surely it is only a matter of time.
