Researchers warned attackers could 'defrost the food' months before French supermarkets got hit
They tried to sound the alarm in August
Security experts had raised concerns about vulnerabilities in refrigeration controllers months before cyberattacks crippled hundreds of French supermarkets. The hackers targeted Danfoss and Copeland refrigeration controllers, causing food to spoil and triggering fires in nearly 700 supermarkets. France's national cybersecurity agency (ANSSI) warned of widespread compromises involving Danfoss and Copeland systems.
These compromised devices were accessible over the internet and often running outdated software. Despite the availability of patches, security firm Coalition reported that critical exposure to these threats persisted well into the fall. As of October, 618 Danfoss devices remained connected to the internet, with 206 in France, 50 in the US, and two in the UK.
OT cybersecurity experts urged for stronger food and agriculture protections in the US, emphasizing the importance of implementing baseline cybersecurity measures to prevent such incidents.
