…According to a new study published by AT&T Labs, the prime source of unauthorized copies of new movies on file-sharing networks appears to be movie industry insiders, not consumers. The study is "the first publicly available assessment of the source of leaks of popular movies," according to its authors.

Nearly 80 percent of some 300 copies of popular movies found by the researchers on online file sharing networks "appeared to have been leaked by industry insiders," and nearly all showed up online before their official consumer DVD release date, suggesting that consumer DVD copying represents a relatively minor factor compared with insider leaks.

"Our conclusion is that the distributors really need to take a hard look at their own internal processes and look at how they can stop the insider leaks of their movies" before taking measures that might hamstring consumers' technologies and rights, said Lorrie Cranor, a researcher at AT&T Labs and lead author of the study.
