Emulating Samsung’s Baseband for Security Testing

Дата: 26.02.2021. Автор: CISO CLUB. Категории: Подкасты и видео по информационной безопасности

The most crucial interface between modern mobile phones and cellular networks are baseband processors. Basebands are responsible for processing the complicated 2G thru 5G protocols, which gives them a large attack surface. Unfortunately, exploring this surface is cumbersome: finding flaws over-the-air is not scalable, crashes are difficult to reproduce, and devices typically lack even basic debugging interfaces.

To address these concerns, we designed and built an emulation environment for Samsung’s «Shannon» baseband (ShannonEE). We leverage and combine the strengths of two existing frameworks, avatar2 & PANDA, to provide a flexible and extensible platform geared towards vulnerability research.
