PyQBDI 0.8.0

Python binding for QBDI

Introduction

QuarkslaB Dynamic binary Instrumentation (QBDI) is a modular, cross-platform and cross-architecture DBI framework. It aims to support Linux, macOS, Android, iOS and Windows operating systems running on x86, x86-64, ARM and AArch64 architectures. In addition of C/C++ API, Python and JS/frida bindings are available to script QBDI. Information about what is a DBI framework and how QBDI works can be found in the user documentation introduction (User Documentation).

QBDI modularity means it doesn’t contain a preferred injection method and it is designed to be used in conjunction with an external injection tool. QBDI includes a tiny (LD_PRELOAD based) Linux and macOS injector for dynamic executables (QBDIPreload). QBDI is also fully integrated with Frida, a reference dynamic instrumentation toolkit, allowing anybody to use their combined powers.

A current limitation is that QBDI doesn’t handle signals, multithreading (it doesn’t deal with new threads creation) and C++ exception mechanisms. However, those system-dependent features will probably not be part of the core library (KISS), and should be integrated as a new layer (to be determined how).

Status

CPU	Operating Systems	Execution	Memory Access Information
x86-64	Android, Linux, macOS, Windows	Supported	Supported
x86	Android, Linux, macOS, Windows	Supported	Supported
ARM	Linux, Android, iOS	Planned (*)	Planned (*)
AArch64	Android	Planned (*)	Planned (*)

Warning

The ARM and AArch64 instruction sets are supported but they still need to be integrated along with x86 and x86-64.

Installation

Python API (PyQBDI)

PyQBDI is available through PyPI. The wheel package can be either downloaded or installed with the following command:

pip install PyQBDI

The PyQBDI package is self-contained so completely independent from the C/C++ package.

Devel packages

There is no strict development timeline or scheduled release plan for the QBDI project. All the new features and fixes are merged onto the dev-next branch. Devel packages can be downloaded in the artefacts of:

• Appveyor for Windows packages PyQBDI

• Github Actions PyQBDI Linux for Linux PyQBDI

• Github Actions PyQBDI OSX for OSX PyQBDI
