Sony Fights Back against Torrents and file sharing service using Denial of Service attacks and using Fake SeedsThe Fightback
The Fightback
According to Recode, Sony has started using various several technological countermeasures to disrupt downloads of its most sensitive information through torrents and file sharing services. Recode says that Sony is using hundreds of computers in Asia to execute what’s known as a Denial of Service (DoS) attack on the file sharing sites where its stolen data has been identified to be hosted. Sony is adopting a special technique called ‘Fake Seeds’ against those using torrents to download and upload its stolen files. The procedure for employing this technique is rather complex. When a user is downloading a file through any torrent software, the user download parts of the file simultaneously from several ‘seeders’ and ‘leechers’ to facilitate a faster and unbreakable download. The ‘seeders’ facilitate the full download of torrent whereas the ‘leechers’ facilitate download of bits and parts of the file and hosting it. Normally all torrent users act as some kind of ‘leechers’ in the torrent ecosystem. When the user download the full file he/she turns into a ‘seeder.’ Sony has taken this idea forward by employing what are called as ‘fake seeds.’ Sony is cloning the seeds with its own dummy files contain gibberish data yet big enough in size and seeding this fake seeds into the torrent ecosystem so that it will sap a downloader’s software resources, bringing download speed to a crawl. The basic idea behind this variation is to frustrate the downloader into giving up the file download and not being part of the stolen files torrent ecosystem. Recode states that Sony used a similar kind of technique in the early days of file sharing services. “Sony’s technique is similar to one it employed in the early days of file sharing, when it worked with an anti-piracy firm called MediaDefender. The firm populated file-sharing networks with decoy files labeled with the names of such popular movies as “Spider-Man,” to entice users to spend hours downloading an empty file.” Sony is already bearing huge financial costs of its unreleased movies being shared online and possibility of litigations over the hack attacks. It remains to be seen how these techniques will help Sony but it may help the entertainment major to recover some of its lost morale and pride.
