JBS-Style Ransomware Is a Farm-Gate Risk: A Vendor Checklist for Protein Producers

A 2021 ransomware attack forced meatpacking giant JBS to halt operations at 47 sites worldwide and temporarily lay off staff — and the Bioeconomy Information Sharing and Analysis Center (BIO-ISAC) says today's livestock barns carry the same exposure through their robotic milking parlors, automated feeders and ventilation controls.

The warning comes as attackers armed with AI tools have struck critical infrastructure in recent months, including wastewater pumps and supermarket refrigeration systems, causing food spoilage downstream. But Andrew Rose, BioAg advisor to BIO-ISAC, argues the problem sits just as close to the farm gate.

"Every connected device is a digital attack surface," Rose told AgFunderNews. "A cyber incident during peak production can escalate into a supply chain disruption."

The record backs him. In 2023, cybercriminals locked a Swiss dairy farmer out of his herd's health records and demanded $10,000. A calf died in utero, and the farmer had to euthanize the cow as well. In meat and dairy, downtime has fast and often devastating consequences, Rose notes, because connected systems run everything from animal health monitoring to delivery logistics.

What Can Producers Actually Ask Vendors?

Rose and the BIO-ISAC insist no operation, large or small, is powerless. "Our adversaries know the weak points and exploit them, but businesses don't have to be a soft target," he said. "Organizations that ask better cybersecurity questions today are well positioned to protect the supply chain and national security."

The center's checklist starts with basics: whether agtech and equipment vendors can change default passwords, enable multifactor authentication, and whether shared passwords exist between facilities, integrators, technicians and support staff.

"Shared accounts eliminate accountability," Rose said. "Default passwords remain one of the most common entry points in an agricultural environment, and using MFA can dramatically reduce the risk of credential theft and remote compromise."

The takeaway: password hygiene is the cheapest control a producer can buy, and the most often skipped.

Who Owns the Data the Barn Generates?

Operational data in the protein sector — genetics, animal health records, feed formulations, production metrics, logistics and supplier relationships — is sensitive business intelligence. Rose says producers should press vendors on:

• What data the system collects, and where it is stored
• Who owns it, and whether the vendor shares, monetizes or sells it
• Whether data can be exported in a usable format or deleted on request
• Retention periods and which third parties — partners, integrators, consultants, AI systems — can see it

Why Flat Networks Are a Single Point of Failure

Many farms, feed mills, hatcheries and processing plants still run flat networks where operational technology, office systems, cameras, Wi-Fi and industrial controls share one environment. It is cheaper to set up, but lacks internal firewalls — one compromised camera could take down the whole operation.

"Segmentation reduces the blast radius of a cyber incident," Rose said. "Offline functionality helps protect animal welfare, environmental controls, food safety, and continuity of operations."

Vendor questions here cover encryption in transit and at rest, segmented-network support, behavior when internet access is lost, open ports, remote desktop requirements and VPN support.

Patches, Liability and Legacy Equipment

Food and ag equipment often stays in production for one to two decades, and unpatched systems are common ransomware targets. Producers should ask how updates are delivered and tested, how long the product will be supported, average response time to critical vulnerabilities, and what happens when older hardware can no longer be updated.

Liability matters too, because adopting connected technology means inheriting the vendor's supply-chain risk. Questions include breach notification timelines, documented incident response plans, who pays for downtime, animal loss, food safety issues or regulatory penalties, and whether the vendor carries cyber insurance.

Remote Hands, Exit Plans and People

Remote diagnostics are now standard across livestock, refrigeration and feed systems, but unmonitored access creates exposure. Producers can demand access logs, individual technician accounts, the ability to disable remote access, and role- or time-based restrictions.

End-of-life planning is equally concrete: what happens if the vendor is acquired, merges or fails, whether equipment stays functional without cloud connectivity, and whether parts will exist in 5–10 years. Vendor lock-in plus weak security support creates "long-term operational risk throughout the protein supply chain," Rose said.

Finally, human error remains a leading cause of incidents across critical infrastructure — phishing training, USB restrictions, and prompt removal of terminated employees round out the internal checklist. BIO-ISAC's message is that resilience, including manual overrides for feeding, watering, ventilation and refrigeration, is now an animal welfare issue as much as an IT one.
