                <![CDATA[Fuzzowski-based OPCUA fuzzer.

Fuzzing should never be conducted on production equipment or systems. This testing technique can cause unexpected behavior, system crashes, data corruption, or security vulnerabilities. Always perform fuzzing in a controlled, isolated environment to ensure the safety and stability of production systems.

FuzzySully is an OPC UA fuzzer built upon Fuzzowski. It is a specialized testing tool designed to identify vulnerabilities and bugs in OPC UA (Open Platform Communications Unified Architecture) implementations. These fuzzers typically operate by generating and sending a large number of malformed or unexpected messages to an OPC UA server or client, with the goal of triggering unexpected behavior or crashes.
