Experts warn US utilities vulnerable to 'Trojan Horse' cyber threats after French freezer attack

Cybersecurity experts cite a cyberattack on French supermarket freezers as a warning that U.S. critical infrastructure, particularly utilities, may already be compromised by 'Trojan Horse' intrusions. The claim is based on expert commentary rather than confirmed incidents, and the extent of any U.S. compromise remains unverified. The significance lies in the potential for undetected, long-term access to essential services.
