Cyberattacks disrupted grocery store refrigeration systems across Europe, leading to food spoilage and financial damage. This is the second instance in less than a month, with a previous attack in October affecting French stores. These incidents have sparked concern over the vulnerability of essential infrastructure and connected “smart” technology.
Fredrik Sandberg’s photograph shows ICA supermarket employees discarding spoiled food in Stockholm after similar issues hit ICA and Coop stores. Experts worry that smart devices, marketed for convenience, could serve as entry points for hackers.
Home Vulnerabilities
Cybersecurity experts emphasize that homes may be at risk. Dr. Manny Niri of Oxford Brookes University notes that smart appliances like fridges and TVs are small computers online, prone to hacking. Common issues include weak security settings and outdated software.
Professor George Loukas from the University of Greenwich warns that vulnerabilities in mass-produced devices could affect millions of households simultaneously. A flaw in a popular model could endanger every home using it.
Potential Consequences
Hacking could go beyond turning devices on or off. Loukas explains that if an app can control your heating, cameras, or locks, hackers can too. Unauthorized access could reveal when people are home, their activities, and even conversations.
Devices on the same network might get compromised, exposing personal information. There could be physical consequences like changing a fridge’s temperature or disabling security systems. In 2025, a U.S. vulnerability in WiFi thermostats was identified, highlighting similar risks.
Mass Scale Attacks
The greater danger lies in exploiting vulnerabilities across millions of devices. The 2016 Mirai malware transformed home devices into a tool for large-scale attacks. Artificial intelligence makes these attacks easier and more accessible.
Loukas suggests that with AI, extensive disruption can now be orchestrated by fewer individuals. When millions rely on the same technology, a single flaw becomes a widespread issue.
Addressing Concerns
Experts advise awareness without panic, stating that ordinary households are less likely to be targeted. Niri highlights the need for vigilance, questioning the necessity of smart functions and considering potential hacking consequences.
To mitigate risks, change default passwords, enable two-factor authentication, regularly update software, and maintain manual control over crucial systems.
