Editor's note: This post was originally published in June 2019 and has been revamped and updated for accuracy and comprehensiveness. The latest update was in November 2021. In a previous article we saw how we could steal an API key by performing a man in the middle (MitM) attack to intercept the HTTPS traffic between the mobile app and the API server. In this article we will learn how to mitigate this type of attack by using a technique known as certificate pinning. Read Full Story

This walk-though will show us how simple it is to integrate Approov in a current API server using Python and the Flask framework. We will see the requirements, dependencies and a step by step walk-through over the code necessary to implement Approov in a Python Flask API. Before we tackle the integration of Approov we need first to know how Approov validation is processed in the server and how to setup the environment to follow this walk-through. Note that this article assumes a basic understanding of the Approov mechanics. If you need an overview of that, please read first the Approov Product page. Read Full Story
