Paranoia and ProxyHam: High-Stakes Anonymity on the Internet

Presented at DEF CON 23 (2015), Unknown date/time (Unknown duration).

From the US to China and beyond, anonymity on the internet is under fire - particularly for whistleblowers. National interests are pushing for greater control and monitoring of internet content, often invoking harsh punishments for informers and journalists, if caught. While a range of technologies (such as ToR) can provide some level of anonymity, a fundamental flaw still exists: a direct relationship between IP address and physical location. If your true IP is ever uncovered, it's game over - a significant threat when your adversary owns the infrastructure.

To resolve this issue, I present ProxyHam, a hardware device which utilizes both WiFi and the 900Mhz band to act as a hardware proxy, routing local traffic through a far-off wireless network - and significantly increasing the difficulty in identifying the true source of the traffic. In addition to a demonstration of the device itself, full hardware schematics and code will be made freely available.
