Best resources to learn web security attacks?
I'm very interested in web application penetration testing. I went over every good Youtube video on that subject and most of the books. I'm reading Tangled web at the moment. Thanks to those resources I've reported many vulnerabilities on sites in my country and had a chance to expand my knowledge and meet some cool people. If you know any valuable resources, free videos or free courses please post link here. Thank you very much.
