We now have new torrent links in collections for most of the past DEF CON Media. For torrents, there are many clients including BitTorrent (most platforms), uTorrent (most platforms), and Transmission (OS X, Unix, Linux, and some embedded systems). There are tons more out there, We encourage you to find the ones that work for you!
If you could do us a favor as these files build p2p momentum, leave your client running for a bit after you download to share these files and help spread the media love!
