Cybersecurity Threats in Digital Agriculture: A Systematic Review on Emerging Risks and Protective Strategies for Farmers

The rapid digitization of agriculture-driven by the Internet of Things (IoT), Artificial Intelligence (AI), drones and cloud-based farm management systems-has significantly enhanced productivity, precision and sustainability. However, this technological integration has concurrently exposed the agricultural sector to escalating cybersecurity threats. This systematic review synthesizes evidence from 100 peer-reviewed and grey literature sources (2013–2025) to identify, categorize and analyze cyber risks specific to digital farming ecosystems. Following PRISMA-inspired screening protocols, 78 studies met inclusion criteria based on relevance, methodological rigor and geographic diversity. Findings reveal that ransomware, phishing, denial-of-service (DoS) and IoT-based attacks are the most prevalent threats with documented cases causing operational disruptions, livestock loss, financial fraud and supply chain paralysis—as observed in incidents involving AGCO (USA), Federated Co-op (Canada) and Swiss dairy farms. Critically, smallholder farmers in developing economies such as India remain highly vulnerable due to low digital literacy and inadequate infrastructure. This review makes a unique contribution by integrating technological, policy and farmer-centric perspectives to provide a holistic understanding of cybersecurity within Agriculture 4.0. It evaluates existing mitigation frameworks, including India’s National Cyber Security Policy (2013) and Digital Agriculture Mission (2021–2025), while proposing advanced solutions such as AI-driven threat detection, blockchain-secured data ledgers, and cyber-resilient agritech design. A 13-point cybersecurity protocol for farmers is validated through empirical case studies. The study concludes that implementing these measures through collaborative policymaking, targeted digital literacy initiatives, and secure-by-design agritech systems can significantly strengthen cyber resilience in agriculture, ensuring both technological progress and farmer protection. This work fills a critical gap in agrarian cybersecurity literature and offers actionable insights for policymakers, extension services, and technology developers.
