Attackers hacked older Danfoss refrigeration controllers at French, Belgian and Dutch supermarkets and forced the defrost cycle to run continuously at up to 50°C, spoiling large stocks. Reports say 250-350 stores were hit, though the true scale is unclear. For a Thai shop or cold-chain operator, the lesson is practical: check whether your refrigeration or cold-room controllers are internet-connected, change default passwords, restrict remote access, and make sure outdated firmware is updated. Keep temperature alarms that notify you by phone, not only on-site.
