Dairy Processors Face Rising Cyber Threats as Criminals Target Critical Infrastructure

TL;DR Cybercriminals are increasingly targeting UK dairy processors, exploiting their critical‑infrastructure status and time‑sensitive operations to launch ransomware and AI‑related breaches.

Context The dairy sector relies on interconnected systems—from automated milking to temperature controls—that must run continuously. Disruption can spoil products, harm consumers, and interrupt supply chains. Because of this, attackers view processors as high‑value targets.

Key Facts IBM’s 2025 Cost of a Data Breach Report puts the global average breach cost at $4.88 million in 2024, a figure that can cripple midsize dairy firms. Criminals specifically choose food‑processing facilities because they are critical infrastructure with tight production schedules, increasing the likelihood that victims will pay ransoms to avoid downtime. Meanwhile, 97% of organizations that reported AI‑related security incidents lacked proper AI access controls, leaving models and data exposed to manipulation or theft.

What It Means Attacks often begin with phishing emails that deliver ransomware, using techniques such as T1059.001 (PowerShell) to execute malicious code and T1486 (Data Encrypted for Impact) to lock operational technology. Once inside, threat actors may tamper with monitoring sensors, risking product safety, or steal proprietary formulations for competitive gain. The financial toll includes not only ransom payments but also remediation, regulatory fines, and lost sales.

Mitigations Defenders should isolate OT/SCADA networks from corporate IT using strict firewalls and unidirectional gateways. Apply vendor patches promptly, prioritizing CVEs affecting PLCs and HMI software. Enforce multifactor authentication on all remote access points and monitor for anomalous PowerShell or script execution. Maintain offline, encrypted backups of critical configurations and test restoration quarterly. Conduct regular phishing simulations and AI‑governance training to ensure access controls are properly configured.

What to watch next Regulators may issue new guidance on AI security in food production, while threat groups continue to refine ransomware tactics aimed at maximizing operational impact.
