Hackers Target European Supermarket Freezers, Raising Temperatures to 122 Degrees

Supermarket refrigerators and freezers across at least half a dozen European countries suffered a coordinated cyberattack on Monday. Stores in Ireland, Belgium, Luxembourg, Sweden, the Netherlands, Finland, and Estonia watched helplessly as their commercial refrigeration units were forcefully heated up to 50 degrees Celsius, or 122 degrees Fahrenheit. Major retail chains including Ikea, Carrefour, Delhaize, and SuperValu bore the brunt of the incident.

The breach mirrors a similar string of attacks recorded in France last month, which resulted in millions of euros worth of spoiled food being discarded. U.S. military bases faced comparable tampering with their refrigeration systems over the summer. While investigators work to trace the source, early indications point toward vulnerabilities in internet-connected refrigeration controllers manufactured by Danish firm Danfoss. These connected assets often left maintenance ports exposed online despite previous warnings following the French incidents.

Security researchers note that these attacks bypass traditional ransomware motivations entirely, functioning instead as pure sabotage designed to spoil inventory and force store closures. Industry experts emphasize that basic firmware fail-safes, such as hardcoding limits preventing freezers from accepting high-temperature commands, are glaringly absent in many commercial cooling architectures. European cybersecurity agencies continue to investigate the breach as geopolitical tensions heighten scrutiny over vulnerable critical infrastructure worldwide.
