CTF Starter

A template for deploying challenges to ACM Cyber's CTF platform for Cyber Academy & CTF After Dark. For more information, please see https://github.com/uclaacm/cyber-platform.

Deploying

In order to begin deploying this to the ACM Cyber platform, start by updating ctf.toml. Notice the example fields below.

start = 2022-05-18T18:00:00-06:00
stop = 2022-05-25T18:00:00-06:00

These indicate the starting and stopping time of the CTF. The platform will not accept flags if the stop time has passed so its important to update this. Be sure to match the correct formatting of the times (here is a resource that can help convert times).

Once this is updated, make sure that all of the events and challenges within their corresponding folders pass the TOML checker. With that, you are ready to deploy the platform!

Challenges

Follow the format of the challenges/example/challenge.toml to create a challenge!

Creating Challenges

Each challenge should correspond to a directory within the challenges/ directory. Make sure to push both source and compiled Linux executable. Also check that the executable runs on the SEASnet servers.

Regarding challenge.toml, follow this example. Some things to keep in mind:

• Aim for value to range between 10 and 100.
• If you're presenting the next week, set enabled to true; otherwise, false.
• Your first tag should signify which workshop the challenge comes from. For example, "file" for File Analysis, "packet" for Packet Captures, "memory" for Memory Forensics.
• files should contain relative paths, description should link by filename.

Challenge Creation

Below contains an example of what the challenge.toml file should look like. This is a good starting point for creating your own challenge.

# This is a short abbreviation of your challenge name used to help create the URL for your challenge on acmcyber.com.
slug = "example-challenge"

# This is what your challenge is called.
title = "Example Challenge" 

# This is you! Put your name here! :)
author = "Jerry"

# How difficult your challenge is. Challenge points range from 0-100. 
value = 10

# Your challenge description supporting markdown.
description = """What is the name of the president of ACM Cyber from 2019-2020? Example of challenge [file](file.txt). Example of [link](https://acmcyber.com)."""

# Short abbreviation to descrbe what category your challenge is in. NOTE: You can only put ONE in the list.
tags = ["intro"]

# Any files that you reference in your challenge description. Leave an empty array [] if you have none.
files = ["file.txt"]

# Your prized solution!
flag = "flag{sanjana_aka_death}"

# Whether your workshop is this week or not.
enabled = true

Events

Follow the format of the events/example/events.toml file to create an event!

Event Creation

Each event should correspond to a directory within the events/ directory. Make sure to include an icon.svg within every event folder!

Regarding event.toml, follow this example.

Event Creation

Below contains an example of what the event.toml file should look like. This is a good starting point for creating your own event.

# This is the unique event ID for your event. This should be a unique number.
id = 1

# This is the title of your event. ex. 'Cyber Academy: Intro to Web Hacking'
title = "Example Event"

# This is the short name of your event. This is the abreviated reference on acmcyber.com's Events page. ex. 'Intro Web'
short = "example"

# This is the date of your event. ex. 'Wednesday 1/1 6:00PM-8:00PM PT'
date = "Wednesday 1/1 6:00PM-8:00PM PT"

# This is the description of your event. ex. 'Learn the basics of web hacking!'. This supports markdown.
description = """Description in Markdown here."""

# This is the link to your event's Zoom meeting.
link = ""

# This is the link to your event's slides.
slides = ""
