The cyberattacks targeting commercial refrigeration systems aren’t going away. What began with attacks in France in October has since expanded to incidents in other regions, raising bigger questions about the security of connected equipment. And one of the most alarming details? According to French prosecutors, attackers weren’t just manipulating temperatures, they were also disabling the safety alerts designed to warn operators something was wrong.
Matt Wyckhouse, CEO of connected product security company Finite State, says these attacks expose a much bigger problem: what happens when hackers can compromise both physical equipment and the safeguards meant to protect it?
On Iran and what made the attack dangerous
“We used to joke about putting your refrigerator on the internet. But a grocer has a good reason to know at two in the morning that a freezer is warming up. France attributed the October attacks to a cyber unit of Iran’s Revolutionary Guard, and French prosecutors say the attackers disabled safety alerts as well. If the same system can change the temperature and silence the warning, what protection is actually left? That’s a question for the people who design the controller as much as it is for the people who run the store.”
On why a patch isn’t the finish line
“Embedded patching is hard and much slower than what we see in web apps. I’ve seen small security fixes have unintended consequences. One patch accidentally changed how much power a chip drew and shut off a camera sensor while it was recording. The manufacturer caught it before it shipped. That’s the reality of fixing software that controls physical equipment: you have to close the security hole and prove the equipment still does its job. I’d ask how long it took to protect the last freezer, not how fast the vendor posted a patch.”
On what AI changes
“A refrigeration controller can still be running perfectly years after the manufacturer stops supporting it. AI is bringing down the time and expertise it takes to find flaws in that old firmware. I haven’t seen public evidence that AI was used in the French attacks, but I wouldn’t wait for that proof to act. Manufacturers can use the same tools to find problems in equipment they’ve already shipped and give operators time to decide what they can safely update, what they need to isolate, and what they need to replace. You want to make those decisions on a maintenance schedule, not at two in the morning with a freezer warming up.”
