What problem does it solve?

This Skill helps identify vulnerabilities in MQTT broker implementations by fuzzing them against the MQTT 3.1.1 specification, ensuring robust security and protocol compliance.

Core Features & Use Cases

  • Comprehensive Protocol Coverage: Tests all MQTT 3.1.1 packet types including CONNECT, PUBLISH (all QoS levels), SUBSCRIBE, UNSUBSCRIBE, PING, and DISCONNECT.
  • Edge Case and Malformed Packet Testing: Identifies weaknesses by sending invalid remaining lengths, malformed UTF-8 strings, and incorrect wildcard usage.
  • Use Case: A security engineer can use this fuzzer to proactively discover and fix potential buffer overflows or denial-of-service vulnerabilities in an IoT device's MQTT communication layer before deployment.

Quick Start

Run the MQTT fuzzer against a broker running on localhost at port 1883, including malformed and edge-case packets.
