CNet looks at the leak of tons of confidential information from Media Defender, a company that thwarts and gathers evidence against alleged online copyright infringers. A few thousand of their emails, most of their important source code, and even recorded audio of phone conversations have all been stolen and posted online, in part due to shoddy security practices. The information reveals a company that is willing to push up against and sometimes cross ethical lines in order to pursue file sharers. John Palfrey (my boss twice removed) is spot-on with his comments on the ethics of the thing. As is Hilary Rosen, former head of the MPAA, who suggests that perhaps Media Defender needs to spend a bit more time defending themselves.
