Hackers Already Inside American Utilities, Cyber Experts Warn
Cyber experts warn hackers could be inside U.S. utilities, posing 'Trojan horse' threat.
In brief
Cyber experts warn hackers could be inside U.S. utilities, posing 'Trojan horse' threat. Cybersecurity experts say hackers may already be inside American utilities, risking widespread disruption. Originally reported by Fox News.
French Supermarket Cyberattack

French supermarkets faced millions in losses after refrigerators overheated overnight.
“Unknown hackers took over the refrigeration in hundreds of supermarkets across France, raising temperatures above 100 degrees Fahrenheit overnight, causing massive spoilage”
John Walsh on U.S. Vulnerabilities

Cybersecurity expert John Walsh warns U.S. critical infrastructure is vulnerable to similar attacks.
“Think about if we don't have water for seven days, or if they attack freezers and we don't have food”
Legacy Systems at Risk
U.S. critical infrastructure uses 15-20 year old systems that no longer receive updates.
“A primary obstacle in [operational technology] environments, whether in food manufacturing, pharmaceuticals, oil, or utilities, is that facilities operate assets that are 15 to 20 years old”
Security vs. Resilience
Cybersecurity shifts from preventing attacks to assuming hackers are already inside systems.
“Security is kind of like, 'I feel i can trust that things are okay.' Resilience is where you make the assumption the attacker is present”
Trojan Horse Threat

Hackers could already be inside electrical grids and other critical infrastructure.
“A so-called trojan horse could already be inside america's electrical grid and other critical infrastructure, just waiting for the adversary to activate it”
Real-World Examples
2026 cyberattack on Minnesota water systems shows similar vulnerabilities exist.
“We see the adversary, potentially a geopolitical adversary, basically practicing their art and demonstrating their art in different locations”
What Happens Next
U.S. needs governance to push industries to implement cybersecurity protections.
“We're definitely more vulnerable, they're definitely targeting us, and citizens, government, and the international community need to get governance in place to push industries to implement these protections”
In short
Cybersecurity experts say hackers may already be inside American utilities, risking widespread disruption.
