Suspected cyber-attacks on European supermarket freezers raise tech vulnerability concerns
Researchers have identified hundreds of refrigeration interfaces linked to British retailers that are accessible via the public internet.
Supermarkets in Europe have been targeted by suspected cyber-attacks affecting their refrigeration units, according to a BBC News report. The incidents have raised questions regarding the security of internet-connected hardware, ranging from industrial machinery to domestic appliances.
Researchers from UK Cyber Defence have found more than 800 building-control and refrigeration interfaces linked to British retailers that can be accessed over the public internet. While this does not confirm they can be hacked, it could leave them open to attackers using software vulnerabilities or weak passwords.
Ciaran Martin, former chief executive of the National Cyber Security Centre (NCSC), stated that manufacturers must do more to provide safer products. He advised consumers to use multi-factor authentication and keep devices updated.
The NCSC said it is working with industry and international partners to investigate the supermarket incidents, though it is unaware of any impact in the UK. Since April 2024, UK law has required manufacturers of certain smart devices to meet minimum security standards regarding updates and passwords.
Helen Dickinson, chief executive of the British Retail Consortium, said cyber incidents are a major concern for retailers. She noted that businesses are working with the NCSC to share intelligence and improve defences.
Tom Hegel, a researcher at cyber-security firm SentinelOne, said retailers must clarify who owns the security of equipment rather than just who repairs it. He noted that changing a setting could destroy physical stock rather than just interrupting a computer system.
