DEF CON 24 - Grant Bugher - Bypassing Captive Portals and Limited Networks
Channel: DEFCONConference
Date: 2016-11-13

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.
