libdebug ![DOI]()

libdebug is an open source Python library for programmatic debugging of userland binary executables.

libdebug provides a comprehensive set of building blocks designed to facilitate the de of debugging tools for different purposes, including reverse engineering and exploitation. Build Your Own Debugger!

With libdebug you have full control of your debugged executable. With it you can:

Access process memory and registers

Control the execution flow of the process

Handle and hijack syscalls

Catch and hijack signals

Interact with stdin, stdout, and stderr of the debugged process

Debug multithreaded and multiprocess applications with ease

Seamlessly switch to GDB for interacti

Debug on Linux systems based on AMD64, AArch64, and i386

When running the same executable multiple times, choosing efficient implementations can make the difference. For this reason, libdebug prioritizes performance.

Installation

Install from another branch

If you want to stay up to date with the most cutting-edge features (and you don't mind being on an unstable branch) you can install from a different branch (e.g., dev).

Please visit the build guide for more information on how to manually build libdebug from source.

Your first script

Now that you ha installed, you can start using it in your scripts. Here is a simple example of how to use libdebug to debug a binary:

The abo will run the binary test in the working directory and set two breakpoints: one at the function function and another at function2.

The first breakpoint has no callback, so it will just stop the execution and wait for your script to interact with the process. When the process stops at this breakpoint, you can read and write memory, access registers, and so on. In the example, we print the value of the RAX register and write a string to memory. Then, we continue the execution of the process.

The second breakpoint has a callback that will be called when the breakpoint is hit. Inside a callback, you can interact with the process, read and write memory, access registers, and so on. At the end of the callback, libdebug will automatically continue the execution of the process.

There is so much more that can be done with libdebug. Please read the documentation to find out more.

The cool stuff

libdebug offers many ad features. Take a look at this script doing magic with signals:

Auto Interrupt on Command

libdebug also allows you to make all commands execute as soon as possible, without having to wait for a stopping event. To enable this mode, you can use the auto_interrupt_on_command=True
