Defenders versus Pentesters on Multifactor Authentication

Cybersecurity Perceptions Versus RealityAs part of our research on Cybersecurity Perceptions Versus Reality, we developed a survey in collaboration with Serene-risc, a knowledge mobilization network in cybersecurity based in Canada, on the perceptions and practices of cybersecurity professionals. The survey aimed at understanding how defenders perceive specific security measures and whether these measures were implemented in their respective organizations.

Bypassing Xamarin Certificate Pinning on Android

Xamarin is a popular open-source and cross-platform mobile application development framework owned by Microsoft with more than 13M total downloads. This post describes how we analyzed an Android application developed in Xamarin that performed HTTP certificate pinning in managed .NET code. It documents the method we used to understand the framework and the Frida script we developed to bypass the protections to man-in-the-middle (MITM) the application. The script’s source code, as well as a sample Xamarin application, are provided for testing and further research.
