Empty Shelves at Grocers: The Importance of Cybersecurity

Empty grocery shelves are often blamed on supply chain disruptions, labor shortages, or transportation challenges. Increasingly, however, cybersecurity incidents are becoming another critical and often overlooked cause of operational disruption in the grocery industry.

Continuing cyber incidents affecting grocery organizations reinforce a troubling reality: When systems supporting ordering, distribution, or inventory management are compromised, the impact can quickly reach store shelves. While not every incident makes the news, the operational consequences are very real for grocers and their customers.

In this article we’ll explore an example of a recent cyber breach, its impact on operations, and measures you can use to help improve cybersecurity. Understanding these key points can help your organization recognize potential threats, implement effective strategies to safeguard your data, and enhance the resilience of your operations.

How ransomware attacks can impact grocery store owners

A regional grocery retailer experienced a ransomware incident after a cybercriminal gained access through a trusted third party. Attackers first compromised the email account of one of the grocer’s wholesale vendors and remained undetected for an extended period. Using that access, they sent a convincing phishing email to a grocery store employee.

When the employee clicked the email and unknowingly shared login credentials, the attackers were able to access the grocer’s corporate network through a remote connection not requiring multifactor authentication. Once inside the network, the attackers exploited additional vulnerabilities to elevate their access and ultimately deploy ransomware, locking systems across the organization and disrupting operations.

Common cybersecurity challenges for grocery store owners

What makes these incidents particularly challenging is that they are rarely isolated events. Many grocers continue to operate with gaps in cybersecurity controls, limited visibility into system vulnerabilities, or outdated response plans. As a result, cyber incidents don’t just affect back-office systems; they can interrupt ordering, delay deliveries, and limit product availability.

Industry conversations suggest these types of disruptions are more common than public reporting reflects. Even when incidents are resolved quickly, the operational ripple effects can linger, reinforcing the importance of proactive cybersecurity planning.

Why cybersecurity risk management matters for grocers

Protecting sensitive data

Retailers handle sensitive information, including personal and financial data. It’s common for retailers to have loyalty programs collecting data on their customers. This data can help companies be more efficient and drive growth, but it can also make them prime targets for cyberattacks.

Threat actors find various ways to monetize cyberattacks, disrupting operations by selling stolen data or locking up systems.

To help protect sensitive data, implement robust cybersecurity measures such as regular security audits, employee training on data protection, and by using advanced encryption technologies.

Complying with contractual requirements

Companies that store, process, or transmit credit/debit card data are subject to the Payment Card Industry Data Security Standard (PCI-DSS). A data breach involving an organization’s card data can lead to fines or penalties.

Retailers outsourcing payment processing and using PCI-approved point-to-point encryption (P2P) payment terminals are still responsible for their PCI compliance and have requirements they need to meet.

Compliance is an ongoing process, but you can start by conducting a thorough assessment of your current systems and processes to help identify any gaps between existing practices and PCI-DSS standards.

Maintaining operational resilience

Disruptions caused by threat actors can severely impact a retailer’s operations. Ransomware is a common attack where the threat actor deploys malicious software encrypting systems and data, making the systems and data unusable. The threat actor then demands payment to decrypt or unlock the systems and data. A ransomware attack can be very costly, both from the ransom payment itself and the lost production when the business can’t use its technology.

This risk has evolved due to retailers’ increasing reliance on vendors and third parties. Threat actors are taking advantage of this by targeting vendors, which impacts the vendors’ customers.

To help sustain operational resilience, develop and implement robust incident response plans tailored to address ransomware attacks and breaches originating from third parties, including regular assessments and monitoring of third-party security practices.
