Food spoiled at at least six U.S. military-base locations after unusual refrigeration failures in late August. The Pentagon is investigating whether cyberattacks caused the apparently near-coordinated breakdowns, but officials have not publicly confirmed an intrusion or identified who might be responsible.
The equipment didn’t simply stop working. According to Reuters, someone or something changed refrigeration temperature settings in at least one case. That could point more strongly to manipulation of the control system than an ordinary mechanical fault, though it does not establish that a hack occurred.
One particularly unusual incident happened at Fort Huachuca in Arizona. In an August 26 post on its Facebook page, the base reported that its freezers had switched into defrost mode, effectively warming the food inside. During the morning inspection, staff found only spoiled supplies.
The failures affected military grocery stores, also known as commissaries, where personnel buy food on base. Cybersecurity specialists from the U.S. Army Criminal Investigation Division are investigating alongside the Pentagon’s cyberwarfare unit.
Investigators have also looked beyond the United States. A military official said they contacted their French counterparts after a recent cyberattack affected commercial refrigerators in French supermarkets. A related report on the French incident described refrigeration equipment being heated to 50 degrees and food being discarded across several large grocery chains, with potential losses of several million euros following the attack overnight into Monday. Officials have not publicly established a connection between that attack and the U.S. failures.
Food safety is at risk whether a refrigeration unit breaks down or its controls are compromised. In 2026, the Global Food Safety Initiative, a food-safety organization, warned that food-industry professionals and IT leaders need to work together to protect refrigeration technology. A hacked cooling system, the organization cautioned, can be just as dangerous as a malfunctioning one.
