Bypassing Captive Portals and Limited Networks

Presented at DEF CON 24 (2016), Aug. 6, 2016, noon (30 minutes)

Common hotspot software like Chilispot and Sputnik allow anyone to set up a restricted WiFi router or Ethernet network with a captive portal, asking for money, advertising, or personal information in exchange for access to the Internet. In this talk I take a look at how these and similar restrictive networks work, how they identify and restrict users, and how with a little preparation we can reach the Internet regardless of what barriers they throw up.
