  • Eijah, Cam - Dig Dug: The Lost Art of Network Tunneling

    Abstract:

    Saturday from 0900 to 1300

    In a world of decreasing privacy, it's important that users can communicate P2P without any reliance on centralized solutions. But how do computers connect directly to each other without having external IP addresses, using an insecure protocol like UPnP, manually port forwarding, or routing through intermediary services like Signal, Skype, or Telegram? The traditional solution to this problem has been to trust companies and just route our data though their servers. We can totally trust them, right? If the future of secure communication depends on companies to route our traffic, then I would argue that the future of communications is insecure. There must be a better solution more in line with privacy fundamentals.

    Reverse Network Tunneling, i.e. UDP Hole Punching, is a powerful technique that makes it possible for computers with internal IP addresses that are inaccessible on the Internet to be able to connect to each other directly, and therefore become accessible. As crazy as this sounds, it's real and works. This has multiple applications in the real world, such as allowing a pentester to directly connect to a victim that is hidden behind a router. Network tunneling also invalidates the need of centralized services provided by companies that log, surveil and profit from our traffic. Imagine how the future of secure communications would change if all of our online interactions were off-the-grid?

    This workshop shows you how to punch holes through external routers to allow computers that were once hidden from the Internet to connect to each other P2P. If you've ever wanted to tunnel into private networks and access internal computers, then this workshop is for you. Create a botnet, backdoor, or even the next great privacy app - the sky's the limit! This is a beginner-level, technical workshop and requires that attendees have some prior experience in at least one programming language, such as Python, JavaScript or C++. Bring your laptop and a strong appetite for pwning network devices.
