Understanding the prevalence of web traffic interception

This post contributes to the understanding of web traffic interception by presenting research findings on its prevalence, methods, and security implications. It details the technical mechanisms of interception (local and remote), the role of trusted certificate authorities, and the use of TLS fingerprinting to detect interception. The post quantifies interception rates (4-10%), breaks them down by OS and browser, and categorizes interceptors by motivation (security vs. malicious). It also explains how insecure cryptographic implementations by interceptors weaken overall security.
