Check out the stories of hackers who grew with Dreamhack.
The cybersecurity field has high entry barriers for beginners, but Dreamhack has excellent curriculum and wargames. With few Korean wargame sites available, I'm very satisfied with the quality problems and coordinated learning lectures.
- 6rmA7YOc7ZeM7J6F64uI64ukLg==
I wanted to study security since childhood but had nowhere to find resources or get help. Since Dreamhack launched, I've been able to learn the topics I was curious about from theoretical foundations.
- reinusKR
Other platforms often only provide wargames with many problems that can't be solved without foundational knowledge. Dreamhack is the only place where I can learn fundamental concepts through lectures and then solve related problems.
- reaunper
It helps people who don't know where or how to start studying cybersecurity by providing a systematic learning path.
- dlruddms
The most difficult period is when you're first starting out. In any security field, beginners spend the most time and face the most challenges, and Dreamhack has been a tremendous help during this phase.
- 나임
I'm satisfied with the systematic curriculum and high-quality explanations that help understand difficult concepts through visual materials and practical exercises.
- 1s0m0rph1sm
The learning lectures have excellent examples and summaries, and the curriculum and practices that make you feel like you're gradually growing increase both interest and concentration.
- HappyCode0806
Even beginners can start studying various fields without pressure, and the appropriate mix of theory and practice makes it more enjoyable and easier to understand.
- lo7u5
It's great because it teaches well even to people who are new to security or have zero understanding, and provides an environment where you can practice after watching the lectures.
- 플래그를even하게익히는남자
Thorough, systematic, and explains things in a way that beginners can easily understand.
- YunGoon
It's useful for building technical knowledge about situations you might encounter in a professional environment.
- m1n1
Helpful for improving skills as a RED team member.
- 빈센트
New wargames applying the latest technologies are consistently released, and just solving these problems greatly helps improve information security skills and learn about new vulnerabilities.
- oolongeya
It's great that CTF problems using the latest CVE vulnerabilities allow us to quickly learn about new vulnerabilities and practice attack methods.
- swap
When solving problems on various wargame sites, many can be solved without specific knowledge. Dreamhack's wargames often can't be solved without specific knowledge, which helps with learning.
- ohohohohohohohohoh
It's because I can communicate with various experts and people interested in the same field.
- suechaehua
There doesn't seem to be any other open, active community in Korea where security professionals are actively participating like Dreamhack.
- 해킹다까먹음
It's normally difficult to expect someone to always answer my questions, but having such a community has greatly helped my study progress.
- fake
Various problems are well-organized by field and set up like levels, so the sense of achievement when solving a problem feels greater.
- le0s1mba
You can regularly experience new CTF problems, have opportunities to apply what you've learned, and the ranking system gives you a sense of purpose.
