Insider Knowledge

Terminology
Security ChallengeChallenge

Outsiders describe individual puzzles generally as "security challenges," but insiders shorten this to "challenge," recognizing the specific CTF format.

VulnerabilityExploit

Outsiders refer to a "vulnerability" as a security weakness, while insiders distinguish an "exploit" as the practical code or method to leverage that weakness.

FlagFlag

Though "flag" is widely translated, it universally means the secret token captured and submitted in both outsider and insider contexts.

SubmissionFlag Submit

Outsiders might generically call it "submission," whereas insiders say "flag submit" referring specifically to sending the captured flag to the scoring system.

ToolScript

Non-specialists call hacking aids "tools," but insiders prefer "scripts" to emphasize custom or automated code used during CTFs.

CheatingBoosting

Casual observers call unfair play "cheating," whereas insiders often refer to subtle abuse of game mechanics or exploits as "boosting."

HackingPwn

While outsiders say "hacking" to describe unauthorized access broadly, insiders use "pwn" to specifically mean successfully exploiting or compromising a target in challenges.

HackathonCTF

Outsiders might call any coding competition a "hackathon," but insiders specifically say "CTF" to denote cybersecurity capture-the-flag contests.

White HatBlue Team

General public uses "white hat" hacker for defenders, while the CTF community often uses "blue team" to denote defense roles.

Black HatRed Team

Outsiders say "black hat" for attackers, but insiders use "red team" to represent offensive roles in security competitions.

Greeting Salutations
Example Conversation
Insider
glhf!
Outsider
What do you mean by 'glhf'?
Insider
It’s shorthand for 'Good luck, have fun,' a common way we wish each other well before a CTF challenge.
Outsider
Oh, nice! Sounds friendly and sportsmanlike.
Cultural Context
This greeting sets a positive, respectful tone before a competition, emphasizing enjoyment alongside skill.
Inside Jokes

'There are only two hard things in Computer Science: cache invalidation and naming things.'

A widely circulated humorous quote in programming and security communities, highlighting persistent debugging challenges; CTFers often relate to the difficulty of naming scripts or exploits, and the frustration of tricky technical problems.
Facts & Sayings

pwning a box

Refers to successfully exploiting and gaining control over a challenge machine or system in a Capture The Flag competition.

ret2libc

A common exploitation technique involving return-to-libc attacks, used to bypass certain security protections.

shell acquired

Announcing that you have obtained an interactive shell access on a challenge machine, signaling significant progress.

write-up

A detailed, step-by-step explanation of how a challenge was solved, shared to educate others.
Unwritten Rules

Always share write-ups after the competition.

Sharing detailed solutions fosters community learning and allows others to grow their skills.

Respect other teams; avoid sabotaging or cheating.

The competitive spirit is balanced by honor; violating fairness undermines community trust.

Use team communication tools efficiently and keep sensitive strategies private.

Maintaining operational security within teams preserves competitive advantage and cohesion.

Don't publicly share spoilers during live competitions.

Avoiding spoilers preserves the fun and challenge nature for everyone still competing.

First Steps & Resources

Get-Started Steps
Time to basics: 2-4 weeks
1

Learn CTF Basics

2-3 hoursBasic
Summary: Read beginner guides to understand CTF formats, categories, and rules.
Details: Start by familiarizing yourself with what CTF competitions are, their different formats (Jeopardy-style, Attack-Defense), and common challenge categories (crypto, web, pwn, forensics, reverse engineering, etc.). Reading beginner guides and FAQs from established CTF communities will help you grasp the structure and expectations. Many newcomers struggle with jargon and the breadth of topics, so take notes and look up unfamiliar terms. Understanding the landscape is crucial before attempting challenges, as it helps you navigate resources and avoid feeling overwhelmed. Evaluate your progress by being able to explain what a CTF is, list major categories, and describe how a typical event works.
2

Set Up a Practice Environment

1 dayIntermediate
Summary: Install essential tools and create a safe, isolated workspace for solving challenges.
Details: A proper environment is vital for safe and effective CTF practice. Install a Linux virtual machine (VM) or use a dedicated system to avoid risking your main computer. Set up basic tools like Python, netcat, GDB, and a code editor. Beginners often skip this step or use their main OS, leading to accidental system changes or malware risks. Follow setup guides from the community, and test your environment by running simple scripts or tools. This step is important for both safety and skill-building, as you'll need to be comfortable with your toolkit. Progress is measured by having a working VM with core tools installed and tested.
3

Solve Introductory Challenges

2-5 daysIntermediate
Summary: Attempt beginner-level CTF puzzles on public platforms to build foundational skills.
Details: Start solving real CTF challenges on beginner-friendly platforms. Focus on easy problems in categories like web, crypto, and forensics. Many sites offer 'warmup' or 'baby' challenges designed for newcomers. Don't be discouraged by initial difficulty—it's normal to get stuck. Use hints, write-ups, and community forums to learn from others. Practice basic techniques like decoding, simple scripting, and file analysis. This step is crucial for hands-on learning and building confidence. Track your progress by the number of challenges solved and your ability to explain the solutions.
