This is a slightly disappointing lecture. The reason is that the lecture was good up to the basic assembly for reversing, but the core part of the lecture, malware analysis, is a bit difficult to call it an introductory lecture, and it goes by too quickly and absentmindedly, so there are some parts that are hard to understand. And although the instructor explains well, it is a bit difficult for beginners to understand. That is because when you look at the lecture, the instructor explains it under the assumption that you already know the prior knowledge or related content. When I looked at other people's reviews, they said the same thing as me. Since the experts explain such basic content, the content (specialized knowledge) is not fully conveyed to beginners. But it is not bad. This lecture is not a lecture that analyzes, but a lecture that guides various directions for malware analysis. Another thing to note(?) is that this lecture is a hodgepodge. It combines lectures that were previously recorded and the latest ones. So there is a lot of overlapping content.
