Man-in-the-Middle (MitM) in Mobile Apps – The Risks of Missing Certificate Pinning

Introduction Mobile apps handle sensitive data—banking details, personal messages, and authentication tokens. But many apps remain vulnerable to Man-in-the-Middle (MitM) attacks due to a critical oversight: lack of certificate pinning. When apps fail to implement SSL/TLS certificate pinning, attackers can intercept, decrypt, and manipulate encrypted traffic—putting millions of users at risk. This blog explores how MitM attacks work on mobile
