Beginning on September 14, 2007, MediaDefender experienced a security breach caused by a group of hackers led by high school student "Ethan". This group called themselves MediaDefender-Defenders. According to an SEC filing, this ultimately cost parent company
ARTISTdirect at least $825,000. The breach included emails, a phone conversation, and a number of internal anti-infringement tools, including some source code.
Leaked e-mails On September 14, 2007, 6,621 of the company's internal
e-mails were leaked, containing information contradicting previous statements and details of strategies intended to deceive copyright infringers. The emails link MediaDefender to projects that management previously denied involvement in. The
Associated Press and other media outlets suggest that the leak may confirm speculation that MiiVi.com was an anti-copyright infringement "
honeypot" site. One e-mail suggests using the
MiiVi client program to turn users' PCs into drones for MediaDefender's
eMule spoofing activities. The leaked e-mails discuss responses to unexpected and negative press, and expose upcoming projects, problems in and around the office,
Domino's pizza orders, and other personal information about employees. Beyond strategic information, the leak also exposed login information for
FTP and
MySQL servers, making available a large library of
MP3 files likely including artists represented by MediaDefender's clients. The emails also revealed that MediaDefender probably was negotiating with the New York Attorney General's office to allow them access to information about users accessing pornographic material. The e-mails also revealed direction by MediaDefender founder
Randy Saaf to have developer Ben Ebert attempt to eliminate the information about MiiVi from MediaDefender's
English Wikipedia entry. Ebert responds in an email on the same day saying, "I will attempt to get all to miivi removed from wiki. I should easily be able to get It contested. We'll see if I can get rid of it."
Leaked phone conversation On September 16, 2007, MediaDefender-Defenders released a 25-minute excerpt of a phone conversation between the
New York Attorney General's office and MediaDefender as a
torrent on The Pirate Bay. MediaDefender-Defenders claims in information released with the phone conversation that they have infiltrated the "internals" of the company.
Leaked source code On September 20, 2007, MediaDefender-Defenders released the source code of TrapperKeeper, MediaDefender's decoy systems on The Pirate Bay. A large chunk of MediaDefender's
software was available by Bittorrent. ==Revision3 controversy==
