Well, this could get interesting. Following the leak
of MediaDefender's emails, the folks behind The Pirate Bay now believe they have enough evidence to sue many major entertainment firms
for "infrastructural sabotage, denial of service attacks, hacking and spamming." Basically, there's evidence in the emails that a bunch of firms, including Universal, EMI, Sony, Paramount and others were using MediaDefender to try to mess with The Pirate Bay's system. Whether or not the lawsuit actually goes anywhere may depend on a lot of factors (including Swedish laws, which I am totally unfamiliar with). There may be some questions about how the emails in question were obtained. And, of course, the entertainment companies will likely counter that they were just trying to protect their own materials -- which could find a sympathetic ear in a courtroom. Either way it would be quite a lawsuit.
