In this third and final part of this series, we provide our conclusions about OWE’s ability to address the current wireless threat model, as well as our proof-of-concept attacks against the protocol.

In this second part of the series, we’ll provide an overview of how OWE works. There are already some good write-ups that provide this info at a high level, so this will be more of a hands-on technical deep device.

In early 2019, myself and fellow Denver-based researcher Steve Darracott (@theDarracott) set out to answer the question — “is Opportunistic Wireless Encryption (OWE) susceptible to abuse and attack, and if so, how?”. Ultimately, we succeeded in implementing multiple working proof of concept attacks, which we demonstrated at the DEF CON Wireless Village last summer. This series of blog posts documents our research efforts and conclusions, and discusses how OWE fits into the current wireless threat model.

At DEF CON 25 and Hackfest 0x9 I introduced a novel attack that can be used to bypass port-based access controls in WPA2-EAP networks.

This blog post will cover the development of sentrygun, from the algorithms used to detect rogue APs to the design patterns used to leverage those algorithms by network administrators.
