This technical deep-dive demonstrates how modern fuzzing techniques have been revitalized to uncover critical vulnerabilities in cloud-native applications, moving far beyond their classical C/C++ origins. Focusing on the powerful methodology of Property-Based Fuzzing, this hands-on session guides you through the entire lifecycle—from theory to building and deploying your own fuzzers against Go, Python, Java, and JavaScript codebases. You will leave equipped with the practical skills to architect robust fuzzing strategies, secure your own services, and contribute to large-scale security projects like OSS-Fuzz.
