DEF CON 32 Main Stage · Day 1 · Main Stage
In an era where ubiquitous connectivity defines our digital landscape, the security of mobile network traffic remains a critical yet often overlooked frontier. Aapo Oksman's DEF CON 32 talk, "Leveraging private APNs for mobile network traffic analysis," delves into the significant challenges of monitoring and securing data transmitted over cellular networks, particularly for Internet of Things (IoT) and other specialized devices. While traditional network analysis tools suffice for Ethernet or Wi-Fi traffic, the unique architecture of cellular networks often renders these methods ineffective, creating a blind spot for security professionals and privacy-conscious users alike.
