Four officials told Reuters that investigators treat the incidents as a suspected cyberattack, after a similar attack reportedly hit hundreds of French supermarkets in October. At least six US bases reported problems, including Fort Huachuca and Fort Irwin, when units switched to defrost mode and spoiled food. Records for at least one commissary, at Naval Air Facility El Centro, list a Danfoss control system, though Reuters could not establish whether military commissaries used Danfoss equipment. Cybersecurity firm Claroty reported vulnerabilities, including a hidden login, in Danfoss and Copeland refrigeration controllers in August, and Danfoss has since released a fix. The vulnerabilities do not establish that they were used in either incident. The Pentagon has not explained what caused the failures. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What caused the refrigerator and freezer failures at US military commissary stores in August? The Pentagon is investigating the failures as a suspected cyberattack, according to four officials who spoke to Reuters. Refrigerators and freezers at commissaries on at least six bases, including Fort Huachuca and Fort Irwin, switched into defrost mode and warmed up, spoiling food. The exact cause has not been confirmed, and investigators have not established how systems were accessed. _Follow daily.dev for updates on how this ICS cyberattack investigation unfolds._ ### Were the Danfoss refrigeration control vulnerabilities connected to the French supermarket cyberattack? It has not been established that the Danfoss and Copeland vulnerabilities reported by cybersecurity firm Claroty were used in the French supermarket attacks or the US commissary incidents. Claroty found flaws including a hidden login that could let an attacker fully control a refrigeration system, and Danfoss has since released a fix. Many affected French stores ran old or outdated Danfoss software. _Developers securing ICS deployments can track disclosures like this Danfoss flaw on daily.dev._ ### How many stores were affected by the refrigeration cyberattack in France? About 150 Intermarché stores and nearly 100 Super U shops were affected when attackers reportedly changed refrigeration system settings in mid-October, causing units to defrost overnight. Temperatures inside some units climbed to around 50 degrees Celsius. Many of the affected stores used control boxes made by Danish company Danfoss, some running old or outdated software. _daily.dev keeps infrastructure security teams current on incidents like this refrigeration attack._ --- Tags: [#security](https://daily.dev/tags/security), [#cyber](https://daily.dev/tags/cyber) [View this post on daily.dev](https://daily.dev/posts/pentagon-suspects-hackers-behind-freezer-failures-at-us-base-stores-qammg2ruw) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Pentagon suspects hackers behind freezer failures at US base stores","url":"https://daily.dev/posts/pentagon-suspects-hackers-behind-freezer-failures-at-us-base-stores-qammg2ruw","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/pentagon-suspects-hackers-behind-freezer-failures-at-us-base-stores-qammg2ruw"},"datePublished":"2026-10-29T11:05:01.407Z","dateModified":"2026-10-29T11:10:38.263Z","description":"The Pentagon suspects hackers caused refrigerator and freezer failures at US military commissary stores in August.
