Description

Authentication flaws are among the most critical security risks facing web applications today. Exploiting this type of vulnerability can lead to unauthorized access, bypassing authentication controls, and potential data breaches. Therefore, mastering the ability to identify and exploit authentication vulnerabilities has become an essential and foundational skill.In this course, we dive into the technical details behind authentication vulnerabilities, the different types of authentication vulnerabilities you may encounter depending on the authentication mechanism that the application is using, how to find these types of vulnerabilities from a black-box perspective and the different ways to exploit authentication vulnerabilities. We also cover how to prevent and mitigate these types of vulnerabilities.This is not your average course that just teaches you the basics of authentication flaws. This course contains over 3 hours worth of HD content that not only describes the technical details behind authentication vulnerabilities, but also contains 14 labs that give you hands-on experience exploiting real-world examples. The labs are of varying difficulty levels starting with really simple examples and slowly moving up in difficulty. You'll gain experience in cracking and brute-forcing user passwords, enumerating usernames, exploiting logic flaws in authentication mechanisms, bypassing 2FA authentication and much more!If you're a penetration tester, application security specialist, bug bounty hunter, software developer, ethical hacker, or just anyone interested in web application security, this course is for you!
