4Shared, the largest file-sharing website on the Internet, has been sued in an attempt to reveal the identities of the person or persons who uploaded copyrighted files. The ex parte motionwas filed at a US federal court by Modulo Security Solutions, who are trying to identify the alleged uploader of confidential documents belonging to the company. If successful, the case may have implications for others who share copyrighted files on cyberlockers. While the nature of the case is different from traditional media piracy, its outcome will be watched closely by copyright holders currently suing BitTorrent users. n their complaint Modulo is only asking 4Shared to identify the uploader(s) of the files, not those who have downloaded them.
