Copyright infringement monitors are the latest target of a well-organized, motivated hacking group.

The group calling itself the MediaDefender-Defenders (MDD) has, as promised, struck again, this time leaking what appears to be the full, uncompiled source code to anti-piracy watchdog MediaDefender’s toolset.

MediaDefender’s software is used internally on behalf of clients like the RIAA and Sony BMG to control the illegal distribution of copyright movies, music and other media online. One company e-mail, leaked last Saturday, detailed the performance of the company’s attempts to poison the distribution of pirated copies of “Spiderman 3” just days after its theatrical release.

“The [leak] is complete for their operations regarding Kazaa, bittorrent, gnutella etc. This system is … released for the public in order to identify the decoys [MediaDefender] set up,” states the leak’s accompanying NFO file.

The leak is a treasure trove of information for anyone seeking to better understand the anti-piracy operations of MediaDefender and its ilk. Judging by the sheer quantity of different programs written for each network, BitTorrent seems to be MediaDefender’s largest target, with the leak containing 16 different tools target it. In addition to software for creating bogus media files, the leak includes tools for to control the who’s who of filesharing networks: Ares, DirectConnect, eDonkey2000, FastTrack/Kazaa, Gnutella, Kademlia, Overnet, Piolet, SoulSeek and WinMX networks, among others.

Unlike the previous two leaks, MDD claims it received the leaked source code directly from a MediaDefender employee. and the NFO file ends with “a special thanks to the MD employee that gave this to us.”

While DailyTech has been unable to verify the authenticity of any of the leaked materials, MediaDefender has indirectly validated them through a series of cease-and-desist notices sent to various BitTorrent trackers earlier this week; the letters admit that “despite security precautions by our client, a person or persons illegally accessed MediaDefender’s email and other files,” and that the sites in question “immediately and permanently cease and desist from posting, distributing or otherwise making available MediaDefender’s trade secrets and confidential information.”

Responses have varied, ranging from compliance to outright mockery. In one case, replied publicly in a profanity-laden tirade against MediaDefender’s legal firm.

MediaDefender’s woes began last Saturday, when almost 700MB of the company’s e-mails hit the underground. The following day, MDD released copies of a VOIP conversation between MediaDefender and the New York Attorney General. In a previous NFO file, MDD promised that there was “more to come,” and it looks like the group will continue to make good on its claim.
