- awesome-embedded-security - GEF - GEF (pronounced ʤɛf - "Jeff") is a kick-ass set of commands for X86, ARM, MIPS, PowerPC and SPARC to make GDB cool again for exploit dev. It is aimed to be used mostly by exploit developers and reverse-engineers, to provide additional features to GDB using the Python API to assist during the process of dynamic analysis and exploit development.

README
`GEF` (pronounced ʤɛf - "Jeff") is a set of commands for x86/64, ARM, MIPS, PowerPC and SPARC to
assist exploit developers and reverse-engineers when using old school GDB. It provides additional
features to GDB using the Python API to assist during the process of dynamic analysis and exploit
development. Application developers will also benefit from it, as GEF lifts a great part of regular
GDB obscurity, avoiding repeating traditional commands, or bringing out the relevant information
from the debugging runtime.
## Instant Setup
Simply make sure you have [GDB 8.0 or higher](https://www.gnu.org/s/gdb) compiled with Python3.6+
bindings, then:
```bash
# via the install script
## using curl
$ bash -c "$(curl -fsSL https://gef.blah.cat/sh)"
## using wget
$ bash -c "$(wget https://gef.blah.cat/sh -O -)"
# or manually
$ wget -O ~/.gdbinit-gef.py -q https://gef.blah.cat/py
$ echo source ~/.gdbinit-gef.py >> ~/.gdbinit
# or alternatively from inside gdb directly
$ gdb -q
(gdb) pi import urllib.request as u, tempfile as t; g=t.NamedTemporaryFile(suffix='-gef.py'); open(g.name, 'wb+').write(u.urlopen('https://tinyurl.com/gef-main').read()); gdb.execute('source %s' % g.name)
```
You can immediately see that GEF is correctly installed by launching GDB:
A few of `GEF` features include:
* **One** single GDB script
* Entirely **architecture agnostic**, **NO** dependencies: `GEF` is battery-included and [is
installable instantly](https://hugsy.github.io/gef/#setup)
* **Fast** limiting the number of dependencies and optimizing code to make the commands as fast as
possible
* Provides a great variety of commands to drastically change your experience in GDB.
* [**Easily** extensible](https://hugsy.github.io/gef/api/) to create other commands by providing
d more comprehensible layout to GDB Python API.
* Full Python3 support ([Python2 support was
dropped](https://github.com/hugsy/gef/releases/tag/2020.03) - see
[`gef-legacy`](https://github.com/hugsy/gef-legacy)).
* Built around an architecture abstraction layer, so all commands work in any GDB-supported
architecture such as x86-32/64, ARMv5/6/7, AARCH64, SPARC, MIPS, PowerPC, etc.
* Suited for real-life apps debugging, exploit development, just as much as CTF
* And a lot more commands contributed by the community available on
[GEF-Extras](https://github.com/hugsy/gef-extras) !!

## Documentation
Unlike other GDB plugins, GEF has an extensive and up-to-date
[documentation](https://hugsy.github.io/gef/). Users are recommended to refer to it as it may help
them in their attempts to use GEF. In particular, new users should navigate through it (see the
[FAQ](https://hugsy.github.io/gef/faq/) for common installation problems), and the problem persists,
try to reach out for help on the Discord channel or submit an issue.
