Ethical Hacking of RESTful and GraphQL APIs Training Course

Description

Welcome to the Ethical Hacking of RESTful and GraphQL APIs Training Course

Important note: This course is NOT teaching the actual usage of Burp Suite and its features. This course is a heavily hands-on introduction to both RESTful as well as GraphQL API vulnerabilities. These APIs are very common in modern web and mobile applications.

Your instructor is Martin Voelk. He is a Cyber Security veteran with 25 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.

This course features theoretical introductions into API vulnerabilities followed by practical exploitations of common RESTful API and GraphQL API vulnerabilities. Some labs are being performed utilizing the Portswigger Web Academy Labs. Other labs are performed on standalone VMs such as crAPI and DVGA. As people use different platforms, The training will not show the set up of crAPI or DVGA. But you can install these easily on a free virtualization software like virtual box on Windows or MacOSX. Martin will be solving a lot of labs and 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. This training is highly recommended for anyone who wants to start out in API Penetration Testing or API Bug Bounty Hunting.

Notes & Disclaimer
Portswigger 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. crAPI and DVGA are free as well and can be cloned from GitHub. I will to respond to questions in a reasonable time frame. Learning Web / Mobile 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.
