Story summary

On November 2, 2026, temperatures in refrigerators and freezers at dozens of supermarkets across Europe rose sharply overnight due to suspected cyberattacks. In Sweden, operators ICA and Coop reported incidents affecting several stores, with one store blaming the issue on hackers, similar to attacks last month in France where over 150 Intermarché stores were impacted. The latest wave hit countries including Belgium, Estonia, Finland, Germany, Ireland, Italy, Luxembourg, Romania, and the United Kingdom. Hackers increased refrigerator temperatures to 50 degrees Celsius (122°F), causing food spoilage and raising concerns about vulnerabilities in connected systems. Russian hacktivist groups Noname057(16) and Z-Pentest Alliance claimed responsibility on Telegram but their posts were later deleted, leading cybersecurity experts to express skepticism.

A company spokesperson, Sarah De Meester, said the supermarket chain had established that temperatures in the cooling systems had increased, adding that the incident was being investigated.
