The retail industry is a prime target for cybercriminals due to its reliance on digital infrastructure and the vast amounts of sensitive customer data it processes. Retail cyberattacks are on the rise, including threats like data breaches, ransomware, and payment fraud, posing serious risks to business operations and consumer trust.
Cyberattacks in the retail industry have become more frequent and sophisticated. As a result, retail cybersecurity has never been more critical. To protect sensitive financial and personal information, retailers must adopt robust cybersecurity measures, including advanced threat detection, secure payment processing, and ongoing employee training. Strengthening cybersecurity in the retail sector is essential to mitigating risks and ensuring long-term business resilience.
Retail Cyberattacks: A Growing Concern
The retail sector is no stranger to cyberattacks and remains one of the top targets for bad actors. In recent years, retail cyberattacks have included the use of rogue hardware, such as malicious USB devices, that act with malicious intent, for example, to conduct hardware attacks. These components are often discreet, allowing the attack to go undetected for long periods.
Point-of-Sale (PoS) systems are often networked with other systems, exposing the broader network to vulnerabilities. Once compromised, hackers can access sensitive data such as credit card numbers and personal information, escalating the damage.
Rogue Devices and Supply Chain Vulnerabilities
The supply chain provides another entry point for a cyberattack in the retail industry. Hackers might infiltrate a component of the retailer’s supply chain by manipulating devices in the production line. The Rogue Device can either target one of the suppliers, who might have access to some of the retailer’s data, or attackers might intend for the Rogue Device to reach the end user to target the retailer directly.
Using rogue hardware, like bad USBs, bad actors can conduct a variety of cyberattacks, including a data breach. By exploiting PoS systems or other endpoints, attackers can conduct retail cyberattacks that involve data theft, financial fraud, or operational sabotage. Such attacks can be highly lucrative for cybercriminals who sell stolen data or demand ransoms.
Distributed Denial of Service (DDoS) and Ransomware Attacks
Additionally, Distributed Denial of Service (DDoS) attacks are common in the retail industry. They allow attackers to overwhelm an e-commerce site, shutting down the company’s website and causing lost sales and frustrated customers. The retail industry is also a frequent target of ransomware attacks. In these cases, the enterprise’s systems and files are encrypted, and a ransom payment is demanded in exchange for a decryption key.
Both attack types exemplify the rising frequency of cyberattacks in the retail sector, requiring proactive defense strategies.
Consequences of Cyberattacks in Retail
When a retailer experiences an cyberattack and a data breach occurs, millions of individuals can be affected. Malware, phishing, and other forms of cybercrime can cause severe consequences. Hackers may sell stolen information on the dark web for illegal use. Financial losses, both direct and indirect, can reach millions of dollars, including fines, lawsuits, lost revenue, cleanup costs, and other expenses. Business credibility also suffers, as consumers may see the organization as insufficiently protected. This perception can lead to additional security breaches. Recovering from reputational damage is often difficult, making prevention crucial.
Insider Threats in the Retail Industry
Insiders are a very common threat to the retail industry due to high employee turnover and multiple points of vulnerability. Notably, there is often little cybersecurity training, which is increased by the fact that many people handle aspects of the company’s business processes. Insider threats often occur accidentally, because employees are not aware of the risks their actions pose to the company’s cybersecurity. Although unintentional, insiders can cause significant damage to the organization. Comprehensive cybersecurity training is essential in the retail industry.
Employees cybersecurity education, despite adding some improvements to an organization’s cybersecurity posture, is not enough to ensure full protection. Existing cybersecurity software solutions, and even human monitoring, cannot detect rogue hardware. So, even with knowledge of the various risks, employees can still allow a bad actor to carry out a successful attack. Therefore, a Rogue Hardware Mitigation solution is essential.
Retail Cybersecurity Best Practices
To safeguard against cyber threats, retailers should implement the following best practices:
- Encrypt All Sensitive Data: Ensure that sensitive information, such as credit card numbers, is encrypted both at rest and in transit.
- Segment the Retail Network: Isolate Point-of-Sale (PoS) systems and other critical infrastructure to prevent lateral movement by attackers.
- Perform Regular Data Backups: Regularly back up data from e-commerce websites and PoS systems to mitigate the impact of potential ransomware attacks.
- Deploy Anti-Malware Solutions: Implement comprehensive anti-malware solutions across the network, with timely security patches applied to all software and applications.
- Security Training: Educate employees on cybersecurity best practices, including password hygiene, to reduce the risk of insider threats and compromised credentials.

Sepio’s Platform: Mitigating Retail Cyberattacks
Sepio’s platform offers retailers the visibility and control needed to combat cyber attacks in the retail sector, especially those involving hardware. By detecting and blocking Rogue Devices at the physical layer, Sepio prevents threats before they cause harm.
The solution builds a digital fingerprint of every hardware asset (IT/OT/IoT), identifying devices by their true identity, not just their claimed identity. This granular visibility supports effective zero trust enforcement and strengthens the organization’s security posture.
Physical Layer Defense and Zero Trust Enforcement
With Sepio’s Asset Risk Management (ARM) platform, retailers can enforce zero trust hardware access policies. Any not allowed or suspicious asset is blocked in real-time, ensuring comprehensive hardware attack prevention.
Retailers gain full visibility into every known and unknown (shadow) asset connected to their infrastructure. This level of control is key to preventing hardware level threats and supporting overall business stability.
Gain Control of Your Cybersecurity Risks
With cybercriminals targeting the retail industry more aggressively than ever, it’s time to level up your cybersecurity strategy. Sepio’s patented technology ensures that retail cyber attacks, including those using Rogue Devices, are stopped before damage occurs.
