The volume of advisories across Hitachi Energy, Siemens, and Rockwell suggests ICS systems are under heightened scrutiny from security researchers and likely threat actors. These control systems run critical infrastructure so the disclosure rate is concerning for grid operators. Hitachi's repeated appearance in these advisories indicates they're either finding vulnerabilities proactively or their systems are being actively targeted. Either way, utilities need to accelerate their patch managment cycles because the window between disclosure and exploitaton keeps shrinking.
