IEEE Symposium on Security and Privacy 2024 · Day 1 · Continental Ballroom 5
This talk, presented by Jincheng Wang, Le Yu, and Xiapu Luo, introduces **LLMIF** (Augmented Large Language Model for Fuzzing IoT Devices), a novel approach that leverages the power of large language models (LLMs) to automate and enhance the process of fuzzing Internet of Things (IoT) devices. The core problem LLMIF addresses is the pervasive security vulnerabilities within the communication protocol stacks of IoT devices, which are often difficult to discover using traditional fuzzing methods due to their black-box nature, complex message formats, and implicit dependencies.
AI review
This work presents a compelling, technically sound approach to augmenting IoT protocol fuzzing using LLMs for specification analysis. The ability to automatically infer message formats, dependencies, and reason about response codes in black-box scenarios is a significant advancement, leading to the discovery of 8 zero-day vulnerabilities in commercial devices. This isn't just slapping "AI" on it; it's a clever application with real impact.
