Synopsys analyzed 4.8 billion fuzzing tests performed in 2016 and found that many industrial control system, IoT, and automotive protocols are immature and prone to crashes that may reveal exploitable vulnerabilities; notable affected protocols include IEC-104, IEC-61850, Modbus, CAN Bus, CoAP, and CIP, with some protocols failing within seconds to minutes, prompting a call for increased testing and auditing.
