this whole generative ai and vibe coding thing, to me, has this very strong aura of, like david lynch would say, "big sadness"

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

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.

Yeeesssss…..

I did a thing. while working on native NFC capabilities, i ended up writing a test program which reads all the info from EMV cards (such as Visa/Master/Amex) and dumps it to try and learn the payload.

the info shown in the #GTK interface is fairly basic mostly as demo, but it dumps a lot more to the shell:

it may be possible to use this for malicious purposes with the right skill set, so please use it responsibly =)

This one needs to go viral. Aged well huh?

Test stand is pretty roasted. It is going to take some work to get back up and running.
