The UK’s meat processing industry has been targeted by a series of cyber attacks, a senior security official has confirmed, as fears grow over the vulnerability of critical infrastructure to digital sabotage.
Paul Chichester, director of operations at the National Cyber Security Centre (NCSC), revealed that while the impact on domestic operations has so far remained minimal, the agency is working closely with the affected businesses to bolster defenses and mitigate further risks.
The admission comes as a wave of malicious cyber activity continues to disrupt supermarket chains across mainland Europe. In countries including Ireland and France, hackers successfully breached control systems for refrigeration and freezer units. By overriding temperature settings, the perpetrators caused internal temperatures to rise, resulting in the spoilage of vast quantities of food.
Speaking at the launch of the NCSC’s annual report, Dr. Richard Horne, head of the organisation, highlighted the ease with which these attacks were carried out. He noted that the recent incident in France exploited “legacy technology” that had been left connected to the internet while still utilizing default, factory-set passwords—a security oversight that provided an open door for intruders.
Following his address, Dr. Horne confirmed that GCHQ has been working throughout the night to contact UK-based organisations identified as having similar vulnerabilities. The goal is to alert these companies before they can be targeted in a similar fashion.
When questioned about the potential perpetrators behind the surge in attacks, the NCSC leadership remained cautious. Dr. Horne told Sky News’ security correspondent Tom Cheshire that it is “simply too early to tell” who is responsible for the sophisticated campaign.
The situation has served as a stark reminder of the interconnected nature of modern supply chains and the risks posed by outdated industrial hardware. Security analysts have long warned that as supermarkets and processing plants become increasingly “smart,” the surface area for cyber threats grows significantly.
“These attacks have shown us that this is an ‘all of society’ issue,” said Tom Cheshire. “It is a message we keep hearing from the government, but it is one that is increasingly, and alarmingly, becoming a reality.”
The NCSC continues to urge businesses to conduct immediate audits of their operational technology, emphasizing the importance of changing default credentials and isolating critical systems from public networks.
As investigations continue, industry leaders are bracing for the possibility of further disruption. The government has pledged to keep the public updated as more information becomes available, while the NCSC works to prevent the sabotage of food supply chains from escalating further. For now, the focus remains on patching critical security gaps in legacy systems before they can be exploited again.
