The Pentagon is investigating a possible cyberattack as the cause of malfunctions in freezers at a military base.

The Pentagon is currently considering the possibility that recent malfunctions in freezers at U.S. military bases were not mechanical failures, but deliberate cyberattacks. Reuters reports this based on information from sources within the department. One source noted that military investigators are already coordinating with their French counterparts. This connection stems from a similar intrusion earlier this month that disrupted commercial freezers in France.

The Cyber Command division is working closely with interagency teams and law enforcement officials to trace the incident. The August outages affected stores located on at least six different U.S. military bases. In at least one specific case, the temperature inside the freezers was forcibly raised by an external actor.

A distinct pattern emerged during the night of October 11 to 12. Several hundred supermarkets in France suffered a cyberattack targeting their refrigeration units. The attackers seized control of the remote interface used to manage temperature and defrost cycles for professional fridges made by the Danish company Danfoss. This allowed them to remotely disable equipment across multiple retail chains.

The internal temperature spiked while the defrost mode engaged continuously and at high intensity. The goal was to heat the units up to 50°C. This mirrors the suspected activity on U.S. bases. It is worth noting that Russia reportedly faced a record number of cyberattacks in 2026.
