Our research attempts to determine the source of unauthorized copies by studying the availability and characteristics of recent popular movies in file sharing networks. 77% appear to have been leaked by industry insiders; consumer DVD copying currently represents a relatively minor factor compared with insider leaks. We analyze the movie production and distribution process, identify potential vulnerabilities, and offer recommendations. ... We hope you have enjoyed this tour through evidence of successful insider attacks against the movie industry and will be well equipped to watch out for it in future with utmost vigilance. The alert amongst you will already have discovered how to replicate all the observations made on this page in order to verify our results. We believe that analyses such as ours that have important consequences for policy and technology should be verifiable independently and encourage our readers to partake in this activity.
