700 Supermarkets Hacked: The Real Danger of IT vs OT

A cyberattack caused 700 supermarkets to overheat, melting food and damaging inventory. Here is how it happened. In October 2026, hundreds of French grocery stores faced a massive failure when fridge temperatures spiked to 122 degrees Fahrenheit. The incident highlights the growing friction in IT vs OT environments, where operational technology often lacks the robust defenses of standard corporate networks. The breach specifically targeted legacy Danfoss controllers like the AK-SM800 and AK-SC355. Because these units are discontinued and no longer receive security updates, they became easy targets for attackers looking to disrupt critical infrastructure.
