MediaDefender DoSes Revision3 (you stay classy, Hollywood): Who pays MediaDefender to disrupt peer to peer networks? I don’t know who’s ponying up today, but in the past their clients have included Sony, Universal Music, and the central industry groups for both music and movies – the RIAA and MPAA. According to an article by Ars Technica, the company uses “its array of 2,000 servers and a 9GBps dedicated connection to propagate fake files and launch denial of service attacks against distributors.” Another Ars Technica story claims that MediaDefender used a similar denial of service attack to bring down a group critical of its actions.
