700 megabytes of internal email from MediaDefender, a group of entertainment industry enforcers, has leaked onto the net. The emails detail MediaGuardian's procedures, their internal response to being outed for posting a fake download site to entrap users, the plans to induce users to link to their entrapment site, and the way the company sought to insulate their clients in the motion picture industry from negative publicity arising from their entrapment efforts. There's plenty more there — 700mb is a lot of mail — and I'm sure we'll see all kinds of interesting things in the coming weeks.

Unfortunately for Media Defender – a company dedicated to mitigating the effects of internet leaks – they can do nothing about being the subject of the biggest BitTorrent leak of all time. Over 700mb of their own internal emails, dating back over 6 months have been leaked to the internet in what will be a devastating blow to the company. Many are very recent, having September 2007 dates and the majority involve the most senior people in the company. Apparently this is not the first time that a MediaDefender email leaked onto the Internet.

According to the .nfo file posted with the Mbox file the emails were obtained by a group called "MediaDefender-Defenders". It states: "By releasing these emails we hope to secure the privacy and personal integrity of all peer-to-peer users. The emails contains information about the various tactics and technical solutions for tracking p2p users, and disrupt p2p services," and "A special thanks to Jay Maris, for circumventing there entire email-security by forwarding all your emails to your gmail account"
