It has a boatload of features, see [FEATURES.md](FEATURES.md). ## Why? Vanilla GDB is terrible to use for reverse engineering and exploit development. Typing `x/g30x $esp` is not fun, and does not confer much information. The year is 2023 and GDB still lacks a real hexdump command! GDB's syntax is arcane and difficult to approach. Windbg users are completely lost when they occasionally need to bump into GDB. ## What? Pwndbg is a Python module which is loaded directly into GDB, and provides a suite of utilities and crutches to hack around all of the cruft that is GDB and smooth out the rough edges. Many other projects from the past (e.g., [gdbinit][gdbinit], [PEDA][PEDA]) and present (e.g. [GEF][GEF]) exist to fill some these gaps. Each provides an excellent experience and great features -- but they're difficult to extend (some are unmaintained, and all are a single [100KB][gdbinit2], [200KB][peda.py], or [363KB][gef.py] file (respectively)). Pwndbg exists not only to replace all of its predecessors, but also to have a clean implementation that runs quickly and is resilient against all the weird corner cases that come up. It also comes batteries-included, so all of its features are available if you run `setup.sh`.

Installation is straightforward: ```shell git clone https://github.com/pwndbg/pwndbg cd pwndbg ./setup.sh ``` Pwndbg is supported on Ubuntu 18.04, 20.04, and 22.04 with GDB 8.1 and later. We do not test on any older versions of Ubuntu, so `pwndbg` may not work on these versions. We may accept pull requests fixing issues in older versions on a case by case basis, please discuss this with us on [Discord](https://discord.gg/x47DssnGwm) first. You can also always checkout an older version of `pwndbg` from around the time the Ubuntu version you're interested in was still supported by Canonical, or you can attempt to build a newer version of GDB from source. Other Linux distributions are also supported via `setup.sh`, including: * Debian-based OSes (via apt-get) * Fedora and Red Hat (via dnf) * Clear (via swiped) * OpenSUSE LEAP (via zypper) * Arch and Manjaro (via community AUR packages) * Void (via xbps) * Gentoo (via emerge) If you use any Linux distribution other than Ubuntu, we recommend using the [latest available GDB](https://www.gnu.org/software/gdb/download/) built from source. You can build it as: ``` cd mkdir build cd build ../configure --disable-nls --disable-werror --with-system-readline --with-python=`which python3` --with-system-gdbinit=/etc/gdb/gdbinit --enable-targets=all make -j7 ``` ## What can I do with that? For further info about features/functionalities, see [FEATURES](FEATURES.md). ## Who? Pwndbg is an open-source project, maintained by [many contributors](https://github.com/pwndbg/pwndbg/graphs/contributors)! Pwndbg was originally created by [Zach Riggle](https://github.com/zachriggle), who is no longer with us. We want to thank Zach for all of his contributions to Pwndbg and the wider security community. Want to help with development? Read [CONTRIBUTING](.github/CONTRIBUTING.md) or [join our Discord server](https://discord.gg/x47DssnGwm)! ## How to develop? To run tests locally you can do this in docker image, after cloning repo run simply ```shell docker-compose run main ./tests.sh ``` Disclaimer - this won't work on apple silicon macs. ## Contact If you have any questions not worthy of a [bug report](https://github.com/pwndbg/pwndbg/issues), feel free to ping anybody on [Discord](https://discord.gg/x47DssnGwm) and ask away.
