DVD Jon hacks Media Player file encryption | The Register: "Norway's best known IT export, DVD Jon, has hacked encryption coding in Microsoft's Windows Media Player, opening up content broadcast for the multimedia player to alternative devices on multiple platforms.
Jon Lech Johansen has reverse engineered a proprietary algorithm, which is used to wrap Media Player NSC files and ostensibly protect them from hackers sniffing for the media's source IP address, port or stream format. He has also made a decoder available.
Johansen doesn't believe there is a good reason to keep the NSC files encrypted, because once you open the file with Media Player to start viewing the stream, the IP address and port can be revealed by running the netstat network utility that is included with most operating systems.
The hacker hopes his move will make content streamed to Media Player more widely available to users of alternative players on non-Windows platforms.
Johansen achieved notoriety when he was tried and re-tried in a Norwegian court for creating a utility that enabled him to play DVDs on his Linux PC. Prosecutors, acting in the interests of the beloved US Motion Picture Association of America (MPAA), argued he had acted illegally by distributing his DeCSS tool to others via the internet. This, the prosecution, claimed, made it easier to pirate DVDs."
