This is my first time leaving a comment on Inflearn. I'm a job seeker with internship experience in liquor license management, electronic finance infrastructure vulnerability assessment/penetration testing, and currently doing bug bounty. The reason I purchased this course was to advance my bug bounty skills, but I feel like I learned something even more incredible. Things like "is this really possible?" are actually all possible. Of course, I didn't understand everything in the course. While following along with the practice, the beacon connection didn't work 😢 So I think this is a masterpiece course that I need to watch over and over again. Another thing I noticed is that the course doesn't need to be unnecessarily long - it just pinpoints the key points, so I watched the 8-hour course at 1.5x speed in just 2 days. Overall assessment: I recommend this to those who want to go beyond penetration testing.
