Hacker Machine Interface: The State of SCADA HMI Vulnerabilities

This Trend Micro Zero Day Initiative report reviews SCADA HMI security (2015–2016), categorizing prevalent vulnerability types—memory corruption, credential management, lack of authentication/authorization and insecure defaults, and code injection—through detailed case studies (Advantech, GE, Siemens, Cogent), documents long vendor patch windows (~140–150 days), highlights real-world impacts (Stuxnet, Ukrainian grid), and offers researcher and developer guidance (fuzzing, attack surface analysis, banned-API audits) to reduce exploitation risk.
