In this course, we delve into the intricacies of GraphQL Introspection, a powerful technique for discovering metadata about the data available in a GraphQL endpoint. By following the steps outlined, participants will learn how to identify hidden data that isn't directly exposed by the application. The course provides practical exercises, guiding users through the process of detecting GraphQL endpoints, understanding the structure of introspection queries, and crafting their own queries to extract sensitive information.

Participants will first learn to identify traffic patterns indicating the presence of a GraphQL endpoint. They will then use introspection queries to explore the schema and uncover hidden data. The course emphasizes the security implications of exposing metadata and provides actionable steps to mitigate these risks. By the end of the course, participants will have the skills to write their own GraphQL queries to access concealed information, enhancing their ability to assess and secure applications.
