Experts say it’s important to realize that modern farm technology is vulnerable to attacks by hackers, which could leave the supply chain exposed to further risk. The University of Cambridge issued a report noting that automatic crop sprayers, drones, and robotic harvesters are susceptible to an attack. BBC said both the United Kingdom’s government and the FBI are warning that the cyber-attack threat is growing. John Deere said it’s working to fix any weak spots in its software.

James Johnson, Deere’s chief information security officer, says the company has been working with several ethical hackers to find vulnerabilities. CNH Industrial is also working to improve its security posture.

Benjamin Turner, chief operating officer at a British company called Agrimetrics, said, “Hacking into one tractor can upset a single farmer’s profitability. Hacking into a fleet of tractors can suddenly give you the power to affect yields in whole areas of a country.”
