Unveiled at #TROOPERS25 - Hexagon fuzzing unlocked

Hexagon is the architecture in Qualcomm basebands - they power most of the world's leading smartphones.

Until now, this baseband was out of reach.

We released the first open-source toolchain for system-mode Hexagon fuzzing, presented by Luca Glockow (@luglo), Rachna Shriwas, and Bruno Produit (@bruno) at @WEareTROOPERS

Full post: https://www.srlabs.de/blog-post/hexagon-fuzz-full-system-emulated-fuzzing-of-qualcomm-basebands

How we opened up mobile firmware in 3 steps:
1. Boot real iPhone basebands with a custom QEMU fork
2. Rust-powered fuzzer controls execution via JSON configs
3. Ghidra integration maps coverage across threads

This brings full visibility to Qualcomm’s 4G/5G/GPS stacks.

Reproducible. Extendable. Open source.

Hexagon’s no longer off-limits - mobile security just got a lot more transparent.

Some professional news:

1. I’m now a Special Rapporteur for the Cyber Resilience Act.

2. My company is hiring EU subcontractors with network and security expertise!

Bow Shock Systems won a contract with ETSI to lead development of "vertical" cybersecurity standards for specific products. I'm leading the one for operating systems.

We're looking for people with technical expertise and leadership ability to lead three other verticals.
