The Cybersecurity and Infrastructure Security Agency (CISA) has recently published four Industrial Control Systems (ICS) advisories on May 23, 2023.
These advisories aim to provide up-to-date information regarding security concerns, vulnerabilities, and potential exploits in the realm of ICS.
The released advisories include ICSA-23-143-01, which covers Hitachi Energy products such as AFS65x, AFS67x, AFR67x, and AFF66x. ICSA-23-143-02 addresses security issues specific to Hitachi Energy’s RTU500.

CISA strongly urges both users and administrators to thoroughly review these newly published ICS advisories.
By doing so, they can gain a comprehensive understanding of the technical details surrounding the identified security issues and implement appropriate mitigations to safeguard their ICS infrastructure.
Staying informed and proactive in addressing potential security risks is crucial in maintaining the integrity and resilience of industrial control systems. It is recommended to consult the released advisories directly to access the necessary technical information and recommended actions to mitigate any identified vulnerabilities.
