ctf-tools
This is a collection of setup scripts to create an install of various security research tools. Of course, this isn't a hard problem, but it's really nice to have them in one place that's easily deployable to new machines and so forth.

game | Dwarf Fortress | Something to help you relax after a CTF! |
Usage
To use, do:
# set up the path
/path/to/ctf-tools/bin/manage-tools setup
source ~/.bashrc
# list the available tools
manage-tools list
# install gdb, allowing it to try to sudo install dependencies
manage-tools -s install gdb
# install pwntools, but don't let it sudo install dependencies
manage-tools install pwntools
# uninstall gdb
manage-tools uninstall gdb
# uninstall all tools
manage-tools uninstall all
# search for a tool
manage-tools search preload
Where possible, the tools keep the installs very self-contained (i.e., in to tool/ directory), and most uninstalls are just calls to git clean
(NOTE, this is NOT careful; everything under the tool directory, including whatever you were working on, is blown away during an uninstall).
To support python dependencies, however, make sure to create a virtualenv before installing and using tools (i.e., mkvirtualenv --system-site-packages ctf
. The --system-site-packages
is there for easier reuse of apt-gotten python packages where necessary).
Help!
Something not working? I didn't write (almost) any of these tools, but hit up #ctf-tools on freenode if you're desperate. Maybe some kind soul will help!
Docker
By popular demand, a Dockerfile has been included. You can build a docker image with:
git clone https://github.com/zardus/ctf-tools
docker build -t ctf-tools .
And run it with:
docker run -it ctf-tools
The built image will have ctf-tools cloned and ready to go, but you will still need to install the tools themselves (see above).
Vagrant
You can build a Vagrant VM with:
wget https://raw.githubusercontent.com/zardus/ctf-tools/master/Vagrantfile
vagrant up
And connect to it via:
vagrant ssh
Adding Tools
To add a tool (say, named toolname), do the following:
- Create a
toolname
directory. - Create an
install
script. - (optional) if special uninstall steps are required, create an
uninstall
script.
Install Scripts
The install script will be run with $PWD
being toolname
. It should install the tool into this directory, in as contained a manner as possible.
Ideally, full uninstallation should be possible with a git clean
.
The install script should create a bin
directory and put its executables there.
These executables will be automatically linked into the main bin
directory for the repo.
They could be launched from any directory, so don't make assumptions about the location of $0
!
License
The individual tools are all licensed under their own licenses. As for ctf-tools itself, it is "starware". If you find it useful, star it on github (https://github.com/zardus/ctf-tools).
Good luck!
