--- type: Article title: "MerCuriuzz: a novel black-box fuzzing framework designed to automatically uncover logical vulnerabilities in QUIC implementations" description: Publishes the MerCuriuzz artifact for testing logical failures in QUIC implementations. The method combines segmented interaction mutation, semantic differences and resource-use oracles to expose CPU, memory and availability failures that ordinary crash detection can miss.

You can get more detail in its [Usage.md](https://github.com/k4ra5u/MerCuriuzz/blob/caaef68b43a2dc7269eba28e7ab5aabd7b3215a9/Usage.md). ## How to cite us? This framework is based on our latest research,"Identifying Logical Vulnerabilities in QUIC Implementations", accepted at NDSS '26.

You need to replace the parameters of the original `.sh` file with the program path of the local machine, and modify the content of the ports file in the start directory, which describes the CPU resources and port information used by each QUIC implementation.
