# Pentagon Investigates Potential Cyberattack on Military Base Refrigeration Systems Officials probe freezer failures at US military bases following similar incidents in France. - **Source:** [The Next Web](https://brifing.si/source/afe24b20-b275-4c19-b9a6-8bb3c8babae7) - **Published:** 2026-10-29 - **Topic:** [Software & Engineering](https://brifing.si/c/engineering) - **Original article:** - **On Brifing:** https://brifing.si/s/6dbd2ced-6c84-4032-980c-4b3a6b1a29fb ## Military Base Freezer Failures In late August, refrigeration units at US military commissaries unexpectedly switched to defrost mode, causing significant food spoilage. At least six bases, including Fort Huachuca and Fort Irwin, reported these malfunctions. The Pentagon initially confirmed the technical issues but did not disclose a specific cause during the immediate aftermath of the events. ## Cybersecurity Investigation Initiated Army and Air Force investigators, supported by an Army cybercrime unit, launched a formal probe into the failures. US Cyber Command has since joined the investigation to determine if external actors triggered the malfunctions. Officials are currently coordinating with interagency partners and law enforcement to assess the scope of the potential digital intrusion. ## Connection to French Incidents Investigators are comparing the US base incidents with a similar attack occurring in France during mid-October. Attackers reportedly altered settings on refrigeration systems at hundreds of Intermarché and Super U supermarkets, causing temperatures to rise to 50°C. US officials have engaged with French police to share intelligence regarding these coordinated system failures. ## Danfoss Equipment Vulnerabilities Many affected French stores utilized control boxes manufactured by the Danish firm Danfoss, often running outdated software. While it remains unconfirmed if US commissaries exclusively use Danfoss hardware, records for the Naval Air Facility El Centro list a Danfoss system. The company has not commented on the specific US military base incidents. ## Hidden Login Security Flaws Cybersecurity firm Claroty identified critical vulnerabilities in refrigeration controls from Danfoss and Copeland in August. These flaws included a hidden login mechanism that could grant attackers full system control. Although a fix was released, these vulnerabilities highlight the potential attack surface available to malicious actors targeting industrial control systems globally. ## Scope of Potential Impact The agency managing these facilities operates 235 commissaries worldwide, raising concerns about the breadth of the suspected breach. Investigators have not yet determined if the interference extended beyond the reported locations. The Pentagon continues to analyze whether unauthorized access was gained to the broader commissary network or specific isolated control systems. ## Technical Infrastructure Risks The incident underscores the growing risk of cyberattacks targeting operational technology and industrial control systems. When refrigeration units are connected to networks without robust security protocols, they become vulnerable to remote manipulation. This event serves as a case study for the necessity of patching legacy hardware and securing critical facility infrastructure. ## Strategic Security Implications The investigation remains ongoing as the Pentagon balances transparency with operational security requirements. By treating these failures as a suspected cyberattack, the military acknowledges the evolving threat landscape facing essential base logistics. Future security measures will likely focus on hardening control systems against unauthorized access to prevent similar disruptions to military supply chains. ## Sources covering this story - https://thenextweb.com/news/pentagon-military-base-freezer-failures-suspected-cyberattack — --- _Summary written by Brifing from the original reporting.
