If you're buying a security course, RedRaccoon's course is a must!! If you have even 0.1% of the will to become a security beginner or expert, It's a must! If you resist, don't even think about stepping into security!

The best penetration testing course in Korea, period.

This is a basic simulated hacking course! Even if you don't want to become a simulated hacker, this is a course that IT professionals should take at least once.

I have taken about 35% of the current lectures and will write a review and revise it after I finish it. Advantages: While I was self-studying through lectures or books on information security or development, the most difficult thing was not the difficulty of the concepts and knowledge, but the establishment of a practical environment. I can't say the name of the instructor here, but the level of the lecture is very high and it is a lecture that will never be available in Korea, but I was a little disappointed when I saw that dozens of people, including me, had a hard time establishing a practical environment, but this lecture seems good in that it understands such job seekers and allows anyone to easily use the environment created through Discord. Also, when I asked a question through Discord, they answered clearly, and even if I asked a question outside of the lecture, they explained it in detail as if it was a question related to the lecture. They usually answer questions related to the lecture, but for other things, they are not actually obligated to explain them, but it felt like they were explaining it in an easy way because I was worried that I wouldn't understand the explanation. Disadvantages: Rather than a disadvantage, it seems that the male instructor's communication skills are a little better than the female instructor's. Another thing I was disappointed about was that the field of mock hacking is not an easy field at all, and it involves a lot of knowledge, but the difficulty level of the course was beginner, so I was a little puzzled. But when I listened to it, it seemed like they quickly and superficially taught the prerequisite knowledge required for the mock hacking for 40% of the lecture, and then proceeded with practice based on that knowledge. Because I had focused on CS studies before studying hacking, the CS content learned in the lecture seemed a little shallow until hacking. Of course, since the lecture was made by experts who are obviously more experts than me, the intention was probably to get a feel for the lecture and then study the contents covered in the lecture in depth yourself. (In the actual lecture, they say that CS is a lifelong study.) But the lecture itself is not boring, the delivery is good, and it seems like a comfortable environment that allows you to focus on studying. I think it is one of the few lectures in Korea that is not boring. I will write an additional review after I finish it. Recommended for: Those with some basic knowledge + Those who want to experience mock hacking Not recommended for: Those who are sure about how to study + Those with a lot of basic knowledge -------------------------------------- Review after completing 99.09% of the lecture Oh, I was fooled I realized that the thoughts I had when I watched about half of the lecture were completely wrong. First, I thought you were talking about 10 lab machines for practice like mod3ex or mod3post But separately from that, there were 11 actual mock hacking lab machines (including those in the lecture) such as Hackerbox and Tryhackme I started wondering what this was, but it seems to be really helpful. At the beginning of the lecture, I thought it was a lecture for beginners because it covered basic contents such as Linux commands and usage, but the difficulty of the lab machine was higher than I thought, so I was surprised. LOL In fact, even when I didn't know about the existence of the lab machine, looking at the teaching ability, I didn't regret spending 200,000 won, but it was cheap.. I hope you buy it right away. On the other hand, it's a shame that this kind of person only appeared now.

<Advantages> 1. A good environment for practice - You can quickly build a stable practice environment through Discord without the need for environment setup/setting issues that are always indispensable when studying IT. In particular, lectures that were filmed a long time ago are difficult to set up, but this lecture has no such problems at all. 2. Solid structure from basics to completion - They kindly explain everything from basic Linux commands to mock hacking report writing. Even those who are not familiar with Linux can easily take the lecture. (However, you will need to practice a lot to get used to the Linux shell environment, but I think you can learn even that quickly with redraccoon's raccoon city content.) - Those who already have some knowledge of web hacking or service hacking can organize it by following the flow of the lecture. In particular, they provide a guidebook in addition to the lecture, and if you do not have enough time to watch the video, the guidebook is detailed enough to follow the content just by following the guidebook. 3. Content not available on the market - In the case of Windows, there is no content related to vulnerability diagnosis on the market compared to Linux, but it is covered here, so it was good to study. 4. Various practice problems - You can practice various environments by creating 10 target machines and even doing self-tests. In particular, since it is a high-quality machine that can be solved in various ways rather than a general CTF, if you want to get a job related to mock hacking, you can write a mock hacking report and receive feedback. 5. Quick feedback - They give quick feedback through Discord. Although neither of them are in Korea, if you ask a question on Deco, you will get feedback so fast that you will wonder if they are in Korea. <Disadvantages> 1. Price - Considering the content of the lecture, it is not expensive at all, but it is not a price that you can just take a look at with a light heart. In my case, I decided to buy it after reading the table of contents, but I thought about it again after seeing the price. Of course, at this point, I do not regret buying it at all, and considering the content, it is really cheap. => Overall Review: This is a very high quality content, so if you are hesitant to buy it, I recommend eating a few less chickens and then buying it. ㅎㅎ

24/02/14 I'll give you 5 stars first. I'll come back after listening to all the lectures~! 25/01/09 The best lecture for those who want to work in simulated penetration.

I have seen many similar lectures on security, but My thoughts after watching Red Raccoon's lecture 1. It is the most updated 2. Answers questions and answers well 3. The explanations are readable and visible, so it is fun to watch 4. There are few difficult programs or specific programs, and it works well (Usually there are many, or when you install it, it doesn't work, so you have to find out how to use it) 5. Red Raccoon's unique lab (program) makes it easy to learn (At least from what I've seen from other lectures, the learning hurdle is lower than other lectures, and it's easy to learn by following along) 6. I feel a lot of consideration for beginners, especially since the guidebook contains almost all the necessary content, so it takes less time to look up terms and is easy to understand Conclusion: The educational content itself is detailed and easy to access, so it's easy for beginners to learn I'm not saying that other lectures are wrong, but I'm just picking out the strengths that I felt were unique to Red Raccoon's lectures.
