Paradigm CTF Infra

This repository contains all the files used to host Paradigm CTF. For help and support, join the Discord.

Getting Started

To run the CTF infrastructure locally, simply run the following commands:

To run the CTF infrastructure in kCTF, you'll need to do the following:

Now you'll be able to build and test challenges in kCTF:

Images

Paradigm CTF is hosted using kCTF, a Kubernetes-based CTF platform. Follow the kCTF setup instructions to get a local cluster running on your computer.

kctf-challenge

The kctf-challenge image acts as a standard image on top of the kCTF base image. It's optional, not required, but provides the following features:

Adds the /bin/kctf_persist_env and /bin/kctf_restore_env scripts for use with kctf_drop_privs, which resets all en (this might be removed if a better way of passing configuration is identified)

Adds a common nsjail.cfg for use with Anvil. The usefulness of running the An inside nsjail is debatable, as a lot of security features need to be disabled (timeouts, resource limits, etc). The file is also poorly-named, and may be changed in the future

paradigmctf.py

The paradigmctf.py image acts as the base image for all challenges. It provides the following features:

Installs the ctf_launchers, ctf_solvers, and ctf_server libraries. These can be used to orchestrate CTF challenge instances.

Libraries

forge-ctf

The forge-ctf library provides two Forge scripts which can be used to deploy and sol. They are intended to be used with the eth_launchers package.

The CTFDeployment script can be o to implement the deploy(address system, address player) internal returns (address challenge) function. It defaults to using the test [...] test junk mnemonic, but will read from the MNEMONIC en . It writes the address that the challenge was deployed at to /tmp/deploy.txt, or the value of OUTPUT_FILE.

The CTFSolver script can be o to implement the sol challenge, address player) function. The challenge address must be specified as the CHALLENGE en . The player private key defaults to the first key generated from the test [...] junk mnemonic, but can be o with PLAYER.

Templates

Templates are provided for you to quickly get started with creating challenges of your own. To use them, copy the templates into kctf/challenge-templates. Then, you will be able to use kctf chal create --template eth-pwn.

TODO

Huff support is pretty bad, needs the following changes upstream:

Needs to support broadcasting from specific address

Needs to stop using hexdump to generate some random bytes

Kubernetes support is not complete yet
