Agriculture

Security
CISA has published advisory ICSA-26-057-01 covering pre-authentication remote code execution, information leak and denial of service in Johnson Controls Frick Quantum HD refrigeration controls. The advisory is a documented reason to check exposure, not proof that attacks are occurring.
