The hackers posted the emails on peer to peer networks and reportedly include confidential threads related to asset protection on specific titles. The emails also expose some personal information like social security numbers, emails, and phone numbers.

The most damaging revelations might be regarding the company’s planned MiiVii site that would allow people to upload and download copyright movies, TV shows and music. Apparently, the service would also secretly track people’s activities and report it back to MediaDefender.

In addition to the phone call and emails, blogs are reporting that a huge MySQL database dump from a MediaDefender server was leaked on BitTorrent as well. The database shows tracking and decoy file information for the Gnutella network which is used by P2P clients such as LimeWire.

This is a big set back to MediaDefender’s image with it’s clients. It should serve as a reminder to everyone that much of what we think of as secure is really unsecure.

So here’s the roundup on what people are claiming:

Microsoft announced announced that the company will make search query data anonymous after 18 months by permanently removing cookie IDs, the entire IP address and other identifiers from search terms. In connection with its efforts to support a common industry approach to privacy issues, Microsoft also announced that it will join the Network Advertising Initiative (NAI) later this year when it begins to offer third-party ad serving broadly. And, get this, they even have a Chief Privacy Strategist.

Ask.com recently announced they would start implementing a new service called AskEraser that will offer its searchers control over their privacy when searching for information on the Web. With AskEraser, users of the search site can ensure that their search history will not be retained by Ask.com.

Microsoft and Ask have also joined together to call on the industry to develop global privacy principles for data collection, use and protection related to searching and online advertising.

Microsoft and Ask.com are proposing that leading search providers, online advertising companies and privacy advocates convene to engage in an active dialogue to discuss privacy considerations posed by the proliferation of online advertising and search. The goal of the dialogue is to determine ways that the industry can work cooperatively to define privacy principles that take these new considerations into account. The companies will provide an update on their progress in September.

Yahoo said it would delete identifying addresses and cookies after 13 months unless users want the data held longer or law enforcement agencies require it to store the information for longer.

Google recently announced on its blog that they will anonymize search server logs — including IP addresses and cookie ID numbers — after 18 months, however this seems to conflict a little with an earlier posting describing the time period to be 18 to 24 months.

On a separate front, it will be interesting to see what Google does to Feedburner’s privacy policy now that they are acquiring Feedburner as I raised this concern some time ago. As a side note, Dave Winer has furthered the conversation about Google’s acquisition of Feedburner to raise concerns about the power position Google is building and the risks it creates.
