Description

Welcome to the Business Logic Vulnerabilities Mastery Class – From Zero to Hero!This class combines both theory and practical hands-on lab experience to find and exploit Business Logic vulnerabilities in modern applications (web apps, APIs and mobile).Important note: This course is NOT teaching the actual usage of Burp Suite and its features. This course is proving a step-by-step walkthrough through the practitioner labs with detailed explanations on how to find and exploit web app vulnerabilities.Your instructor is Martin Voelk. He is a Cyber Security veteran with 27 years of experience. Martin holds some of the highest certification incl. CISSP, OSCP, OSWP, Portswigger BSCP, CCIE, PCI ISA and PCIP. He works as a consultant for a big tech company and engages in Bug Bounty programs where he found thousands of critical and high vulnerabilities over the years.This course features all current apprentice and practitioner PortSwigger Web Security Academy lab walk-throughs in the Business Logic vulnerabilities section. In addition, it features a full theory portion which explains the different types of Business Logic vulnerabilities. Martin is solving all these labs and giving useful insight on how to find and exploit these vulnerabilities. He is not just inserting the payload but explains each step on finding the vulnerability and why it can be exploited in a certain way. The videos are easy to follow along and replicate. Martin is also dropping a lot of tips and tricks for real-world Penetration Testing or Bug Bounty Hunting.This training is highly recommended for anyone who wants to become a professional in Web Application Penetration Testing, Web Application Bug Bounty Hunting and wants to focus at 1 vulnerability class at a time.It will feature all Apprentice and Practitioner Labs in the Business Logic vulnerabilities section.The theory portion discusses the concepts around:· Examples· Multi-Step flows· Examples· Finding Business Logic Vulnerabilities· Tips and TricksThe lab portion will feature:· Walkthrough of all Business Logic Apprentice and Practitioner Labs from PortswiggerNotes & DisclaimerPortswigger labs are a public and a free service from Portswigger for anyone to use to sharpen their skills. All you need is to sign up for a free account. I will update this course with new labs as they are published. I will to respond to questions in a reasonable time frame. Learning Web Application Pen Testing / Bug Bounty Hunting is a lengthy process, so please don’t feel frustrated if you don’t find a bug right away. Try to use Google, read Hacker One reports and research each feature in-depth. This course is for educational purposes only. This information is not to be used for malicious exploitation and must only be used on targets you have permission to attack.
