Europe's supermarket freezer hacks: what we know so far (opens the source in a new tab)
- On Monday hackers remotely pushed freezer temperatures as high as 55C in almost 100 stores across Sweden, Finland, Ireland, Belgium, Luxembourg and Estonia, weeks after a similar overnight wave hit French supermarkets.
- The trick was simple: known flaws in internet-linked temperature controllers. Danfoss and Copeland confirmed affected systems; shops kept off the public internet or behind private networks were spared.
- No one has claimed it. A Sentinel researcher suspects a Russia-linked group seeking deniable disruption, and EU officials call it an attack on food security.

Why it matters Cheap hacks with costly results are the new frontier. Freezers, pumps and boilers now sit online, and many owners lack the budget or skills to lock them down.
Other side Blame rests on one researcher's reading of thin traces, and the fix is routine patching. Calling it state warfare could overstate what copycats might also pull off.
