GraphQL is a query language for APIs set to replace RESTful architecture. The use of this technology has achieved rapid adoption and is now leveraged by companies such as GitHub, Credit Karma, and PayPal. Despite its popularity, this new approach to building APIs can leave organizations at risk. While it solves real-world problems, proper implementation is left up to developers who often don't fully understand how to secure their API. Security best practices are easily overlooked, and rushed development can leave cracks in the armor. These issues create a new attack surface for us to explore as well as new ways to exploit underlying infrastructure and code. From Queries and Mutations to Types and Fields, properly attacking a target requires that you understand it. We will learn enough about GraphQL to be dangerous. Demonstrate how to use the technology’s intricacies against itself while taking advantage of implementation errors and misconfigurations. Examine GraphQL specific attacks as well as tried and true techniques adapted to fit into the GraphQL context. Then walk through how to carry out these attacks efficiently and effectively.
