About

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.
