Why the Food and Beverage Sector Faces Heightened Cyber Security Risks
The UK food and beverage sector is increasingly under siege from cyber threats, with attacks targeting businesses of all sizes. In 2023, cyber security breaches across UK organisations reached an all-time high, with food and drink operators ranking as the third most targeted sub-sector in global manufacturing. From ransomware to supply chain vulnerabilities, the risks are mounting as the industry becomes more digitised and interconnected. This blog article explores why this sector faces elevated risks and what makes it a prime target for cyber criminals.
A Growing Reliance on Technology
The rapid digitisation of the food and beverage industry has significantly expanded its vulnerability to cyber threats. Businesses in this sector are increasingly adopting advanced technologies such as the Internet of Things (IoT), artificial intelligence (AI), and smart manufacturing systems to enhance efficiency and reduce costs. However, these innovations come with risks. Legacy operational technology (OT) systems, often decades old, were not designed with modern cyber security in mind. When connected to newer digital systems, they create exploitable vulnerabilities that attackers can target.
For example, ransomware attacks have become one of the most prevalent threats to the sector. These attacks can encrypt critical data or disrupt operational systems, bringing production lines to a standstill. In 2023 alone, over 160 ransomware incidents were documented globally within food manufacturing, with many UK firms affected. Recovery from such attacks often incurs substantial costs, including ransom payments, system restoration expenses, and lost revenue during downtime.
Moreover, the increasing use of AI by attackers has heightened risks further. Cyber criminals now leverage AI to automate sophisticated phishing campaigns and exploit weaknesses in digital infrastructure more effectively. As technology adoption accelerates across the sector, so too does the attack surface available to malicious actors.
Complex Supply Chains: A Weak Link
The food and beverage industry relies on intricate supply chains involving multiple third-party vendors, distributors, and logistics providers. While these networks are essential for just-in-time production and delivery models, they also create significant cyber vulnerabilities. Hackers often exploit weaker security measures within third-party suppliers to gain access to larger organisations’ systems—a tactic seen in high-profile incidents like the Mondelez supply chain breach.
This interconnectedness means that a single compromised supplier can disrupt an entire supply chain. For instance, a ransomware attack on a logistics partner could delay shipments or even halt production entirely. The financial repercussions can be devastating; downtime costs alone can escalate into millions of pounds for larger firms. Smaller businesses face additional challenges as they may lack the resources or expertise to enforce robust cyber security protocols across their supply chains.
Additionally, supply chain attacks can pose risks to food safety and quality. Cyber criminals could tamper with product formulations or manipulate labelling information, potentially endangering public health. As such, securing every link in the supply chain is critical but remains a daunting task for many operators.
Ransomware: The Sector’s Biggest Threat
Ransomware continues to dominate as the most significant cyber threat facing the UK food and beverage sector. According to the National Cyber Security Centre (NCSC), ransomware attacks have already caused substantial business interruptions across industries in recent years, with food manufacturers being particularly hard hit. These attacks are not only financially damaging but also pose risks to national food security due to their potential to disrupt production and distribution.
A notable example occurred in 2024 when several UK-based food manufacturers experienced ransomware incidents that halted operations for days. Attackers often target larger companies based on their perceived ability to pay higher ransoms while viewing smaller businesses as “soft targets” due to their less mature cyber defences.
The consequences of these attacks extend beyond financial losses. Downtime caused by ransomware can lead to empty supermarket shelves or delayed restaurant deliveries—issues that directly impact consumers. Furthermore, reputational damage from such incidents can erode customer trust, making recovery even more challenging for affected businesses.
Economic Pressures and Underinvestment in Cyber Security
Economic pressures within the UK food and beverage sector exacerbate its vulnerability to cyber threats. Many small and medium-sized enterprises (SMEs) struggle to allocate sufficient budgets toward cybersecurity measures due to tight profit margins and rising operational costs. This lack of investment leaves them ill-equipped to defend against increasingly sophisticated attacks.
Even larger companies face challenges in balancing cost-efficiency with robust security measures. For example, legacy systems that underpin many manufacturing operations are expensive to replace or upgrade but remain highly susceptible to cyber intrusions. Without adequate protections in place—such as network segmentation or real-time threat detection—these systems provide easy entry points for attackers.
Additionally, regulatory compliance adds another layer of complexity for businesses. The Information Commissioner’s Office (ICO) can impose fines of up to £17.5 million or 4% of global turnover for data breaches under GDPR regulations. For companies already grappling with operational disruptions caused by cyber incidents, these penalties represent yet another financial burden.
Conclusion
The UK food and beverage sector faces heightened cyber security risks due to its reliance on technology, complex supply chains, and economic constraints. Ransomware remains the most pressing threat, capable of causing widespread operational disruptions and financial losses. Meanwhile, underinvestment in cybersecurity leaves many businesses—particularly SMEs—vulnerable to attack.
To mitigate these risks, companies must prioritise cybersecurity as a strategic imperative rather than an optional expense. This includes investing in advanced threat detection systems, conducting regular risk assessments across supply chains, and adopting a “zero trust” approach where no connection is trusted until verified. Policymakers also have a role to play by providing guidance and support tailored specifically for this critical industry.
As cyber threats continue to evolve in sophistication and frequency, proactive measures are essential for safeguarding not only individual businesses but also the integrity of the UK’s food supply chain as a whole. By addressing these challenges head-on, the sector can build resilience against future attacks while maintaining consumer trust in its products and services.
