DiagNG 0.1.7

DiagNG is a general purpose client purpose for the diagnostic interface of Qualcomm Snapdragon
basebands, present on a large part of Android phones and various USB modems.

It can be considered as a sequel for QCSuper, and also takes large inspiration from SCAT. Like
these tools, it allows to capture 2G/3G/4G/5G air interface network traces and save them to the
GSMTAP/PCAP format, so that you can visualize these in Wireshark.

It is an experimental, Linux-first, open-source, interoperable, brand-new way to connect to
baseband USB diagnostic interfaces; whether for pedagogic or security research purposes.

It should eventually support other basebands such as Samsung Exynos processors, and why not
other protocols such as AT commands.

Features:

• Connect a Linux raw SPI port.

• Connect a Linux raw USB interface.

• A sleek GTK 4/Adwaita-based UI.

• SPI and USB connections are safely connected to the Python UI through a privileged Rust daemon,
using a Polkit/DBus-based interface to secure privileged actions, to ensure good integration
with Flatpak.

• Wireshark plug-in management and automated installation for GSMTAP v3/5G RRC decoding (taken
from SCAT).

• Gather phone-related information through ADB, with shortcuts to enable the QCDM USB interface
easily.

• Import DLF or QMDL files in order to enable interoperability with other software.

• Support basic QCDM (Qualcomm diagnostic monitor) log registration.

• Support basic QCDM 2G/3G/4G/5G log conversion to GSMTAP/PCAP (without advanced features such
as SIB decoding, reassembly).

• Flatpak packaging for good integration to the Linux desktop.
