How to Prevent MitM Attacks between Mobile Apps and APIs

This white paper addresses the increasing threat of Man-in-the-Middle (MitM) attacks on mobile applications and their APIs. It outlines the vulnerabilities that arise from the deployment of mobile apps and the APIs that serve them, emphasizing the inadequacy of Transport Layer Security (TLS) alone in preventing such attacks. The document provides a detailed analysis of MitM attacks, explaining how they can intercept and manipulate communications, leading to unauthorized access to sensitive information. It discusses the concept of certificate pinning as a protective measure against these attacks, highlighting both static and dynamic pinning methods. The paper also examines the risks associated with static pinning and the advantages of dynamic pinning for enhancing security. Furthermore, it presents various scenarios of trust chain breaches, including trust store poisoning and certificate authority breaches, which can facilitate MitM attacks. The goal of this white paper is to equip mobile-first enterprises with strategies to mitigate the risks posed by MitM attacks and safeguard their data and revenue.
