# Getting Started

Welcome to the CTF Wiki.

CTF (Capture The Flag) is originated in the 1996 DEFCON Global Hacking Conference, a competitive game among cybersecurity enthusiasts.

The CTF competition covers a wide range of fields and has a complex content. At the same time, the development of security technology is getting faster and faster, and the difficulty of CTF is getting higher and higher, the threshold for beginners is getting higher and higher. Most of the online information is scattered and trivial. Beginners often don't know how to systematically learn the knowledge of CTF related fields, often taking a lot of time and suffering.

In order to make the CTF players life of entering this field easier, in October 2016, CTF Wiki had the first commit on Github. As content continues to improve, the CTF Wiki has been loved by more and more security enthusiasts, and there are also a lot of friends who have never met participating in this project.

As a free site, with the recent years' CTF challenges, CTF Wiki introduces the knowledge and techniques in all directions of CTF to make it easier for beginners to learn how to getting started at playing CTF.

At present, CTF Wiki mainly contains the basic knowledge of CTF in all major directions, and is working hard to improve the following contents.

• Advanced knowledge in the CTF competition
• Quality topics in the CTF competition

For more information on the above, see the [Projects] (https://github.com/ctf-wiki/ctf-wiki/projects) of the CTF Wiki for a detailed list of what is being done and what to do.

Of course, the CTF Wiki is based on CTF, but it is not limited to CTF. In the future, CTF Wiki will

• Introducing tools in security research area
• More integration with security area

In addition, given the following two points

• Technology should be shared in an open manner.
• Security offensive and defensive technologies are always up to date, and old technologies may fail at any time in the face of new technologies.

CTF Wiki will never publish books.

Finally, the CTF Wiki originates from the community, as an independent organization, advocates freedom of knowledge, will never be commercialized in the future, and will always remain independent and freedom**.

## How to build？¶

This document is currently deployed at [https://ctf-wiki.github.io/ctf-wiki/] (https://ctf-wiki.github) using mkdocs .io/ctf-wiki/). Of course, it can also be deployed locally, as follows:

# 1. clone

git clone [email protected]: ctf-wiki / ctf-wiki.git
# 2. requirements

pip install -r requirements.txt

# generate static file in site/

mkdocs build

# deploy at http://127.0.0.1:8000

mkdocs serve


mkdocs Locally deployed websites are dynamically updated, i.e. when you modify and save the md file, refreshing the page and the contents will be dynamically updated.

Just want to browse locally, don't want to modify the document? Try Docker!

docker run -d --name=ctf-wiki -p 4100:80 ctfwiki/ctf-wiki


You can then access the CTF Wiki by visiting [http://localhost:4100/] (http://localhost:4100/) in your browser.

## How to practice？¶

First, you can learn some basic security knowledge by reading online.

Second, the CTF Wiki has two accompany projects.

• The challenges mentioned in the CTF Wiki are in the [ctf-challenges] (https://github.com/ctf-wiki/ctf-challenges) repository, so look for them according to the corresponding category.
• Note: There are still some challenges that are currently being migrated. . . (misc, web)
• The tools involved in the CTF Wiki are constantly being added to the ctf-tools repository.
