Cybersecurity in food and agriculture means protecting the digital systems used to grow, process, store, move and sell food.

Cyberattacks can stop ordering, payroll, distribution or production; they do not have to reach farm machinery or factory controllers to disrupt operations. The right priority is to identify critical dependencies, prevent common intrusions and prepare a safe way to keep operating or recover.

Farms, cooperatives, food manufacturers, warehouses and retailers have different exposures. In the United States, food and agriculture is one of 16 critical infrastructure sectors, with USDA and FDA acting as co-sector risk management agencies.

What are the biggest food and agriculture cyber threats?

ThreatWhy it matters in this sectorFirst response
Ransomware and data theftOrders, inventory, shipping and plant-support systems may be unavailableIsolated backups, incident plan and network access controls
Phishing and stolen loginsAn email, financial or vendor account can unlock wider accessMFA, verification callbacks and least privilege
Vulnerable remote servicesExposed VPNs and remote support tools can provide an entry pointInventory, supported updates and restricted access
Supplier software outagesScheduling, logistics and cloud services can fail outside the operator’s own networkVendor risk reviews and manual fallback steps
Connected equipment and OT riskRemote connections to irrigation, refrigeration or production controls can affect physical processesIT/OT segmentation and engineering-led maintenance

How common is ransomware? Food and Ag-ISAC recorded 265 food-and-agriculture ransomware attacks in 2025, or 4.2% of the 6,377 events in its cross-sector tracking.

These are events recorded by that organization, not a verified count of every breach or contamination event. Its 2025 analysis identified Qilin, Akira, CL0P, Play and Lynx as leading groups in its data.

A separate Food and Ag-ISAC sector study analyzed 72 threat actors with its Predictive Adversary Scoring System (PASS). That is a count of assessed actors, not 72 confirmed successful attacks. Threat-actor rankings measure relative risk, not attribution for a particular company’s incident.

Where can cyberattacks interrupt the food supply chain?

Farming and ranching: Farm software, connected tractors, water controls, livestock records and suppliers introduce account, remote-access and availability risks. A failed cloud service may delay work without proving an attacker operated a tractor.

Processing and packaging: Production planning and quality records use IT, while production-line controllers, sensors and refrigeration systems are OT. A breach of office IT can force a safe shutdown even if an industrial controller remains untouched.

Storage and distribution: Warehouse applications, temperature monitoring, dispatch systems and carrier platforms need fallback procedures. Loss of monitoring should trigger product-integrity checks as appropriate, not an automatic assumption of spoilage.

Retail and food service: Ordering, employee scheduling, pharmacy, payment and replenishment systems can be disrupted while physical stores remain open.

Six documented incidents that show different risks

IncidentConfirmed impact and key lesson
JBS USA, 2021A ransomware incident interrupted operations. JBS confirmed an $11 million payment and said most facilities were operating at the time of payment. A business-system event can affect physical processing.
Dole, 2023Ransomware affected servers and workstations, but Dole described minimal operational impact while reporting approximately $11 million in total 2023 financial impact. Do not confuse cost with nationwide shortages.
Ahold Delhaize USA, 2024Some pharmacy and e-commerce services were affected after systems were taken offline; stores stayed open. The company later disclosed possible data theft.
Krispy Kreme, 2024Parts of U.S. online ordering were disrupted; shops and fresh deliveries continued. The company later reported material commercial effects.
Blue Yonder / Starbucks, 2024A ransomware outage at the software provider affected customers; reporting linked Starbucks’ scheduling and time tracking to the outage. This was one supplier incident with downstream effects.
fairlife, July 2026Ransomware-related access to some systems, including production-related systems, led to a temporary suspension of U.S. production. Most production had resumed by July 27; the company said food quality and safety were unaffected.

Taken together, these incidents show three different consequences: interruption of physical production, interruption of business services and disruption inherited from a supplier. None establishes that all food-sector cyberattacks cause contamination or national food shortages.

IT vs. OT: what needs different protection?

IT (information technology) runs email, finance, warehouse records, identity systems and scheduling. OT (operational technology) monitors or controls physical equipment, including production controllers and refrigeration. Organizations should coordinate security between the two while keeping appropriate access boundaries.

OT equipment may need a tested maintenance window and manufacturer approval before a patch; a blanket ‘patch everything immediately’ rule can be unsafe. Audit vendor access, keep diagrams of actual connections and plan recovery of controller configurations.

NIST SP 800-82 Rev. 3 remains the final operational technology guide as of October 9, 2026; Rev. 4 is a public draft. NIST issued an additional OT backup guide, SP 1339, in June 2026.

How can an organization reduce cyber risk quickly?

1. Identify the essential process. List the systems needed for safe production, temperature records, shipments, payments and customer service. Identify vendors and manual alternatives.

2. Secure access. Turn on MFA for email, banking, administration and remote tools; remove unused accounts; use dedicated vendor access with limited privileges.

3. Separate systems. Control connections among internet-facing services, office networks, production equipment and third-party technicians.

4. Fix the most dangerous exposures. Prioritize internet-reachable and actively exploited weaknesses; coordinate OT maintenance with engineering and safety teams.

5. Keep recoverable backups. Protect business data and, where applicable, OT logic, approved recipes and configuration files. Test actual restoration.

6. Practice a disruption. Assign incident leads, document safe shutdown decisions and rehearse manual receiving, inventory, ordering and communications where feasible.

7. Review your critical suppliers. Ask about backups, notification arrangements, recovery objectives and alternatives if their service is unavailable.

Small farm or small processor? Begin with MFA on business and equipment-management accounts, a tested offline backup, secure banking procedures, basic updates on office devices and a paper list of equipment-support and emergency contacts.

The Food and Ag-ISAC small-business recommendations and NIST’s CSF 2.0 Small Business Quick-Start Guide are designed for organizations with limited resources.

What should happen during a cyber incident?

First protect physical safety and food quality. Involve both the technical response lead and the person responsible for the affected operation. Isolate compromised systems only in coordination with engineering when physical processes are involved; retain evidence and logs.

Activate approved manual procedures, notify relevant partners and authorities based on applicable requirements, restore trusted systems, and verify production and quality records before returning to normal operations.

Reporting requirements depend on the incident and the organization’s legal obligations. CISA’s CIRCIA implementing rulemaking was still ongoing as of October 9, 2026; the existence of the statute should not be mistaken for an automatically applicable final reporting timetable.

Which official resources help?

CISA’s [Cross-Sector Cybersecurity Performance Goals]: Provide a voluntary starting point, while its April 2024 Cyber Storm IX exercise focused on coordinated food-and-agriculture response.

NIST’s [Cybersecurity Framework 2.0]: OT security guide and small-business quick-start guide support risk-based planning.

Food and Ag-ISAC: shares industry threat analysis and practical guidance. It is an industry collaboration, not a regulator.

USDA and FDA: Coordinate critical infrastructure risk management.

The FDA’s Intentional Adulteration Rule applies to specified food-defense activities with exemptions; it is not a general cybersecurity law for every farm.

Frequently asked questions

Can ransomware shut down a food factory without hacking its controls?

Yes. Unavailable ordering, labeling, scheduling or shipping applications can make continued production impractical even when industrial controllers have not been compromised.

Does a food-company cyberattack mean food is contaminated?

No. Contamination requires separate evidence and food-safety assessment. During a serious incident, organizations should verify process records and product conditions before releasing potentially affected batches.

What are the main farm equipment security steps?

List connected devices, secure management accounts, limit outside access, coordinate updates with manufacturers and preserve the data needed to operate or recover. Risks depend on the machine’s actual connectivity and function.

Is NIST compliance mandatory for every food business?

No. The NIST Cybersecurity Framework is generally voluntary guidance; specific legal and contractual duties vary by company and operation.
