Download Chapter 4: RECONNAISSANCE

Web applications are increasingly using the query language GraphQL to share data, but the security of these useful APIs is lagging behind. Written for hackers by hackers, this hands-on book teaches penetration testers how to identify vulnerabilities in apps that use GraphQL, while introducing a number of exploits that are not yet widely known, and showing readers how to use GraphQL as a hacking tool.

Early chapters provide In-depth knowledge of GraphQL and its query language, as well as the mechanisms of GraphQL APIs. Readers will then be guided through setting up a hacking lab for targeting GraphQL applications, and exploit these APIs with specialized GraphQL security tools. The book also shows readers how to conduct offensive security tests against production GraphQL systems, how to glean information from GraphQL implementations during reconnaissance, and how to probe APIs for vulnerabilities, like injections, information disclosure, and Denial of Service.
