GoKawiilAttack on Danfoss, Dixell and Copeland refrigeration controllers hit 700 French supermarkets
On the night of Oct. 11, an unidentified attacker compromised refrigeration control systems used by hundreds of French supermarkets, forcing freezers and refrigerators into extended defrost cycles. The incident reportedly caused millions of euros in losses across about 700 stores, spoiling food, damaging equipment and sparking some fires. The affected gear included Danfoss controllers with Internet-facing web servers, many still using default admin credentials, alongside Dixell and Copeland XWEB systems.

The scale of disruption suggests that widespread reliance on the same refrigeration hardware and remote-access setups can turn a single technical weakness into a sector-wide crisis, according to SentinelLABS researcher Chris St. Myers, who frames it as a common exposure problem rather than market concentration. Danfoss has told AFP that many compromised units are legacy products no longer receiving firmware updates, which could leave similar equipment elsewhere in Europe's cold-chain supply vulnerable to repeat incidents. France's CERT-FR has urged operators to change default passwords and reset affected devices, pointing to basic security hygiene as a key gap.
- About 700 French supermarkets were hit by a refrigeration-system hack starting Oct. 11, causing millions in damage.
- Danfoss controllers with Internet-exposed web interfaces and default 'admin' credentials were a key weak point, alongside Dixell and Copeland systems.
- Danfoss says many affected units are legacy equipment no longer eligible for firmware updates, raising concerns about lingering exposure.
Ubiquiti UniFi Dream Machine Pro — This incident is a textbook case of why OT devices should never be directly exposed to the internet with default credentials. A UniFi Dream Machine Pro lets you segment IoT and industrial control devices behind a proper firewall and VLANs, giving small businesses enterprise-grade network visibility and control. It's a practical first step toward the kind of network hygiene that could have prevented these refrigeration controllers from being reachable in the first place.
