mitmproxy for fun and profit: Interception and Analysis of Application Traffic

A solid understanding of the protocols used by applications is a necessary prerequisite when assessing application security. In recent projects, we have had to intercept various types of network traffic across different platforms, including Linux, Android, and iOS. The purpose of this article is to introduce the mitmproxy tool and how to use it, as well as the different techniques that can be implemented to effectively intercept these communications, while taking into account the specific characteristics of each environment.
