`pwndbg` (/poʊndbæg/) is a GDB plug-in that makes debugging with GDB suck less, with a focus on features needed by low-level software developers, hardware hackers, reverse-engineers and exploit developers.
|
|
|
|
It has a boatload of features, see [FEATURES.md](https://github.com/pwndbg/pwndbg/blob/dev/FEATURES.md) or these docs.
|
|
|
|
## 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 2020 and GDB still lacks a 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 [300KB][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.

|
## How?
|
|
|
|
Installation is straightforward. Pwndbg is best supported on Ubuntu 22.04 or 24.04 and GDB >= 12.1.
|
|
|
|
```shell
|
|
git clone https://github.com/pwndbg/pwndbg
|
|
cd pwndbg
|
|
./setup.sh
|
|
```
|
|
|
|
If you use any other Linux distribution, we recommend using the latest available GDB built from source. Be sure to pass `--with-python=/path/to/python` to `configure`.
