Enhancing Industrial Security: AI-Assisted Sparkplug B Protocol Fuzzer Released
In May 2026, Bishop Fox released a security fuzzer for the Sparkplug B protocol, a dominant MQTT-based protocol in industrial control and SCADA environments. This tool systematically tests all nine message types, 19 data types, and over 87 unique field paths defined by the Eclipse Sparkplug specification. The fuzzer was developed with AI assistance, specifically utilizing Claude Code to identify coverage gaps and Python defects, resulting in a hardened, self-contained tool with CLI, logging, and passive network discovery capabilities. This development is crucial for ICS and SCADA operators, device vendors, and defenders, as it enables the identification of crashes, protocol violations, and state-handling bugs in Sparkplug B endpoints before attackers can exploit them. The tool is available on GitHub for immediate use.
