Are the Fridges Ok?

Are the Fridges Ok? is an independent watch on internet-exposed supermarket refrigeration controls, focusing on Danfoss StoreView systems. Its blunt assessment is “No”: attacks disrupting refrigeration have recurred, including reported incidents at military bases and European supermarkets from August to November 2026. The problem predates that wave; Danfoss described supermarket refrigeration attacks in Russia and Israel in 2022. The tracker treats the events as a pattern rather than isolated incidents and argues that a quiet news cycle does not mean the risk has passed. Its attack counter resets only for a substantial, reviewed wave affecting multiple sites, using the incident date rather than the later publication date.

Daily monitoring uses Shodan’s indexed service banners, not live vulnerability tests. The headline measure counts distinct IP addresses with a matching StoreView service, while historical exposure and firmware charts count services and may include multiple ports per IP. Neither measure gives a count of fridges or proves compromise; one controller can manage many units, and Shodan’s index may lag. Firmware versions are inferred from cached headers, with ambiguous or unmatched fingerprints left uncertain; apparent shifts do not demonstrate upgrades. A one-time authorized check recognized 212 landing pages among 2,050 eligible IPs, but timeouts, TLS failures, and a discovered checker undercount mean this is not a complete live inventory. Operators are advised to restrict management access, use protected remote access, and apply supported updates.
