Beyond just improving crop yields and reducing input costs, farms can monitor their fields from across the world. They can use drones to get aerial views without trekking through acres and acres. They can keep track of how each cow in their herd is moving, eating and even how much they’re chewing. But an increased reliance on technology could put our farmers at risk. The more tech used, the more opportunities for cyberattacks that could jeopardize the food supply chain.
Automated feeding and watering systems, autonomous soil treatment systems or even smart heat pumps or air conditioners all have the capability of connecting to the internet—they’re known in security circles as “endpoints.” For each of these endpoints on the farm, there is a vulnerability that can be exploited by malicious actors.
To proactively address these risks, it’s critical that software manufacturers in this sector prioritize security in their products and components. Security must be planted into every stage of this supply chain, from the farm to the supermarket, to ensure entire systems remain protected against any potential cyberattacks. These aren’t simply empty threats. Hackers are jail-breaking tractors and they’re using ransomware to go after individual farms. Earlier this month, a Quebec agricultural group, l’Union des producteurs agricoles, dealt with a ransomware attack that impacted its more than 40,000 members.
Agriculture is our most vital industry and it needs cybersecurity
It can be difficult to stay on top of all the risks because of the complexity of the tech and the truly diverse applications of it all. From connected and increasingly autonomous farming equipment to large-scale refrigeration units, manufacturing plants with complex operations and technology and huge transport fleets, each link of the chain presents a potential security threat. Among other best practices, it’s essential that all endpoints are protected with the latest embedded security protocols and that all devices are regularly updated with the latest security patches.
Interestingly, humans have been proven the weakest links in the cybersecurity chain. If organizations adopt “cyber hygiene,” such as using two-factor authentication and making all passwords “long and strong” (and private), this will help guard against some of the most common pitfalls that allow malicious actors in. Unlike farmers, cybercriminals can be quite lazy, so a small amount of protection can cause them to take their malicious activities elsewhere.
To ensure that the food supply chain remains reliable and resilient for all, it’s essential that stakeholders work together to share information and best practices around appropriate cybersecurity standards—this includes software manufacturers, farmers, food processors, retailers and regulators. Education is the best tool for defence across the industry, and ensuring a free flow of information is one way to best protect the food supply chain from start to finish.
Given the costly and devastating consequences that a successful cyberattack could have on the food supply chain, it’s crucial that the agricultural industry takes a proactive approach to cybersecurity, focusing on embedding protection rather than simply reacting to threats after they wreak havoc. As the global population continues to grow, the demand for food increases, making this industry a key target for cybercriminals and bad actors who have the potential to cause widespread disruption on the world stage. The successful integration of technology in agriculture ultimately depends on how well they can invest in robust security measures, conduct regular risk assessment, and ensure all stakeholders are aware of the latest security threats.
It is vital that we apply all the cybersecurity knowledge we have to protect our essential agricultural resources. If you are not a cyberexpert, reach out to the professionals who live and breathe this space every day. An ounce of prevention is worth a pound of cure, and one cyberbreach will be much more costly than taking a proactive approach.
Cyberattacks on modern farming machinery are becoming an increasingly serious threat. Today’s tractors, harvesters, and other equipment rely on autonomous GPS, CAN bus networks, and cloud-connected systems, making them vulnerable to hackers. Attackers can disable steering, change fertilizer or chemical application rates, or lock farmers out of their own equipment using ransomware. Such attacks can cause major crop damage, huge financial losses, and even disrupt food supply chains.Hackers can inject false data into precision farming systems to sabotage planting, spraying, or harvesting.
They can also manipulate CAN bus systems to cause incorrect application of chemicals or take control of irrigation pumps. In some cases, criminals steal valuable farm data such as yield maps and land records or hold machinery hostage during critical planting and harvesting periods.Agriculture remains particularly vulnerable because the sector has traditionally lagged in cybersecurity. Many farmers still use default settings, simple networks, and have limited awareness of risks such as phishing attacks.To protect themselves, experts recommend implementing multi-factor authentication on all farm management software, keeping all equipment firmware updated automatically, and using network segmentation to separate critical farming systems from general Wi-Fi networks.
