Grocery store shoppers at many chains recently ran into an unwelcome surprise: empty shelves and delayed prescriptions. In early November, Ahold Delhaize USA was the victim of a cyberattack that significantly disrupted operations at more than 2,000 stores, including Hannaford, Food Lion and Stop and Shop. Specific details of the nature of the attack have not yet been publicly released.

Because the attack affected many digital systems, some stores were not able to accept credit/debit cards, while others had to shut down online ordering. Additionally, Hannaford’s website was offline for several days. Food supply issues have lasted several weeks in some cases, especially in the New England area, illustrating the impact cyberattacks have on people’s everyday lives.

Cybersecurity in the agrifood industry

The importance of cybersecurity in the food supply chain continues to increase as the agrifood industry becomes increasingly digitized. The increase in smart farming means a cybersecurity attack can even impact growing and harvesting. In addition to the production and distribution processes, a cyberattack can even impact food safety. For example, a cyberattack could interfere with technology that monitors food temperature during production, which can lead to contamination.

Cybersecurity is especially key in this industry because one issue in one segment can quickly compound across the globe. Because of the complex process of bringing food from farm to table, a single vulnerability in one small company can have a major impact on the food supply chain. Additionally, many agrifood companies rely heavily on third-party vendors.

“One challenge with ransomware attacks is that they can cause consequences for suppliers or partners of the victim company, in addition to the direct impact on the victim company itself. Considering the integrated and interconnected nature of the food and agriculture industry, a disruption in one company likely will have a cascading [effect],” according to the Farm to Table Ransomware Report by Food Ag ISAC.

For example, many grocery store chains hire vendors to transport products from warehouses to stores. A cyberattack on the transportation company can shut down critical systems, meaning that food does not arrive as scheduled, which leads to empty shelves.

“Attacks targeting suppliers, distributors or logistics providers can lead to delays in product delivery, shortages or the introduction of counterfeit products. Disruptions in the supply chain can have far-reaching consequences, affecting not only the profitability of companies but also impacting food availability and increasing prices for consumers,” reports Food Safety magazine.

According to Forbes, FBI Special Agent Gene Kowel, speaking at the August FBI Agriculture Threats Symposium in Nebraska, said: “The cyber risk and national security threat to farms, ranches and food processing facilities is growing exponentially. The threats are evolving, becoming more complex and severe.” He also stated that the four key threats facing the agriculture sector are ransomware attacks, foreign malware, data and intellectual property theft and bioterrorism impacting food production and the water supply. Additionally, he warned that foreign entities are actively attempting to destabilize the U.S. agriculture industry.

Recent agrifood cyberattacks

While grocery stores have dominated the headlines lately regarding agrifood cyberattacks, other companies faced cybersecurity attacks in recent years.

In October 2021, Schreiber Foods, a milk processing company, was the victim of a ransomware attack. According to ZDNET, the attack disrupted the entire milk supply due to a change in the digital processes for milk processing. Wisconsin State Farmer reported that milk deliveries resumed five days after the attack. Additionally, milk transporters were unable to access the building and the company faced a $2.5 million ransomware demand.

The highly publicized attack on JBS, the world’s largest meat-packing company, also happened in 2021. Business was disrupted at 47 locations in Australia and nine locations in the U.S. for five days after Russian hacker group Revil encrypted the organization’s systems. JBS reportedly paid $11 million in ransomware following the attack. The attack also led to some meat shortages as well as temporarily higher meat prices.

Farm and Food Cybersecurity Act

To strengthen cybersecurity in the agrifood industry, the Farm and Food Cybersecurity Act is currently in committee in both the U.S. House of Representatives and the U.S. Senate. A key component of the act is that the secretary of agriculture will conduct a study every two years on cybersecurity threats and vulnerabilities within the agriculture and food sectors.

Additionally, the secretary of agriculture will work with other agencies to conduct an annual cross-sector crisis simulation exercise for food-related cyber emergencies or disruptions.

“Food security is national security, so it’s critical that American agriculture is protected from cyber threats,” says Rep. Elissa Slotkin, D-Mich. “No longer just some tech issue, cyberattacks have the potential to upend folks’ daily lives and threaten our food supply — as we saw a couple of years ago when the meat-packing company JBS was taken offline by a ransomware attack. This legislation will require the Department of Agriculture to work closely with our national security agencies to ensure that adversaries like China can’t threaten our ability to feed ourselves by ourselves.”

Reducing the risk of agrifood cyberattacks

Because of the critical nature of their services in relation to the food supply, all companies involved in the agrifood industry should make cybersecurity a high priority. To help improve cybersecurity in the industry, the Cybersecurity and Infrastructure Security Agency (CISA) recently released a Food and Agriculture Cybersecurity Checklist.

Tips from the sheet include:

• Use strong passwords
• Turn on multi-factor authentication
• Recognize and report phishing
• Update software with new versions and patches
• Use cybersecurity tools to mitigate exposure
• Back up your data
• Develop cybersecurity incident response and recovery plans
• Report cybersecurity incidents to www.cisa.gov/report

While the recent empty shelves in grocery stores are a stark reminder of the importance of cybersecurity, the agrifood industry must stay proactive about addressing cybersecurity risks every day of the year.

On September 25, CISA issued a stark reminder that critical infrastructure remains a primary target for cyberattacks. Vulnerable systems in industrial sectors, including water utilities, continue to be exploited due to poor cyber hygiene practices. Using unsophisticated methods like brute-force attacks and leveraging default passwords, threat actors have repeatedly managed to compromise operational technology (OT) and industrial control systems (ICS).

Attacks on the industrial sector have been particularly costly. The 2024 IBM Cost of a Data Breach report found the average total cost of a data breach in the industrial sector was $5.56 million — an 18% increase for the industry compared to 2023. This represents the highest data breach cost increase of all industries surveyed in the report, rising by an average of $830,000 per breach over last year.

Ongoing vulnerabilities pose a serious threat to public safety and national security, especially as water systems and other critical infrastructure providers remain underprepared in the current threat landscape. Let’s take a closer look at the current state of critical infrastructure security, highlighting recent incidents, efforts to address vulnerabilities and the need for further collaboration between the government and private sectors.

Arkansas City Water Treatment Facility attacked

The cybersecurity incident at the Arkansas City Water Treatment Facility on September 22 exemplifies the growing risks. While city officials emphasized that the water supply remained safe and no disruption to service occurred, the breach still forced the facility to switch to manual operations. The incident is currently under investigation, with local authorities and cybersecurity experts collaborating to resolve the issue and prevent further attacks. But the Arkansas City breach is not an isolated incident; it mirrors a larger trend of attacks on water systems.

CISA has issued multiple warnings regarding the susceptibility of water and wastewater systems to cyber threats. Intruders often exploit outdated and unsecured OT and ICS environments, where systems are exposed to the internet or still using default credentials. This means cyber criminals can gain access using relatively simple techniques, which raises concerns about the overall preparedness of critical infrastructure operators.

CISA warnings and hacktivist activity

CISA’s September alert is not the first indication of the heightened threat to water and other critical infrastructure providers. Earlier in 2024, the agency warned that Russia-affiliated hacktivists were actively targeting ICS and OT environments in U.S. critical infrastructure facilities. Water systems, dams and sectors, such as energy and food, were particularly vulnerable to these attacks.

The situation worsened with the rise of the Cyber Army of Russia Reborn, a hacktivist group tied to Advanced Persistent Threat 44 (APT44), commonly known as Sandworm. The group has been quite busy exploiting weak cybersecurity postures of smaller water systems that lack adequate cyber defense resources.

According to Keith Lunden of Mandiant, “We expect these attacks to continue for the foreseeable future given the lack of dedicated cybersecurity personnel for many small- and mid-sized organizations operating OT.” Unfortunately, hacktivist groups have exploited these gaps with relative ease. And without rapid intervention, these attacks will likely continue.

The State and Local Cybersecurity Grant Program (SLCGP)

Amidst the growing cyber threats, the U.S. Department of Homeland Security (DHS) has recognized the need for more support for state and local government cybersecurity. In fiscal year 2024, DHS announced the allocation of $280 million in grant funding for the State and Local Cybersecurity Grant Program (SLCGP). This funding aims to assist state, local, tribal and territorial governments in enhancing their cyber resilience. A special emphasis has been placed on protecting critical infrastructure systems like water utilities, energy grids and emergency services.

These grants will help organizations improve monitoring systems, patch vulnerabilities and implement critical cybersecurity measures such as multi-factor authentication and regular system audits. In states like Michigan, for example, government agencies are already working with local water utilities to provide cybersecurity training and support. The DHS funding could greatly expand these efforts, offering a much-needed boost to the security posture of critical infrastructure providers.

The Cyberspace Solarium Commission

In 2019, the Cyberspace Solarium Commission (CSC) was established by the U.S. Congress to develop a national cyber defense strategy. Currently, approximately 80% of its recommendations have been implemented. However, a final push is needed to address critical gaps, particularly regarding private-sector collaboration and insurance reforms.

One major challenge is identifying the “minimum security burdens” for systemically important entities critical to national security. This would ensure that high-priority infrastructure providers, such as key transportation systems and water utilities, receive the necessary support to prevent catastrophic events.

The CSC also highlighted the need to develop an economic continuity plan for cyber events. This would be nothing less than an incident response and resilience plan to protect the U.S. economy in the face of a major cyberattack. The commission also emphasized the need for better information sharing between government agencies, private industries and international partners to protect critical infrastructure from evolving cyber threats.

During a recent panel discussion, Senator Angus King, co-chair of CSC 2.0, pointed to the difficulties of building trust between the government and private sectors. Private entities own and operate the majority of the nation’s critical infrastructure, but historical tensions make collaboration challenging. King noted that the situation mirrors early tensions that existed between state officials and CISA. Nonetheless, the collaboration between private industry and government is essential to address the growing threat to critical infrastructure.

The state of critical infrastructure cybersecurity

The cybersecurity posture of U.S. critical infrastructure remains a concern. As seen in attacks like the Arkansas City Water Treatment Facility and other incidents targeting internet service providers, threat actors are increasingly focusing on essential services. These attacks are not limited to small municipalities. Larger-scale infrastructure providers, including ISPs and managed service providers, have also been targets.

The FBI recently disclosed that China-linked hackers compromised more than 260,000 network devices, underscoring the scale of the problem. Meanwhile, attacks attributed to the Chinese government have targeted ISPs and managed service providers through vulnerabilities in Versa Networks’ SD-WAN software, demonstrating the growing sophistication of these threats.

While the U.S. government is actively working to improve critical infrastructure cybersecurity, the attacks on water treatment systems and other essential services clearly reveal that more needs to be done. The DHS grant program and the recommendations of the Cyberspace Solarium Commission represent critical steps in this effort, but collaboration between government, private industry and international partners will be key to building a resilient defense against evolving threats.

The safety of critical infrastructure remains a pressing concern. Recent events should serve as a wake-up call for operators, policymakers and the public to take action before a cyberattack occurs that impacts human life and health. Undoubtedly, the threats are real — and any meaningful response requires a concerted effort.
