The retail sector is once again under scrutiny. According to a recent NBC News report, cybercriminals responsible for a string of financially motivated and destructive attacks against top U.K. retailers have now set their sights on major U.S. brands. Google’s Threat Intelligence Group confirmed that “major American retailers have already been targeted,” although names have yet to be disclosed.

In the U.K., companies like Marks & Spencer, Harrods, and the Co-op Group have been impacted ranging from empty shelves and the disruption of online services to the theft of massive volumes of sensitive customer and employee data. Now, it appears this campaign is going global, putting U.S. retailers in the crosshairs.

The threat to the retail sector is both real and escalating. As a professional in the field of cyber exposure management and security, I urge retail leaders to treat this moment as an inflection point. Here’s what retail organizations must do immediately to secure themselves; and what long-term strategies they should implement to take a proactive stance against the next wave of inevitable attacks.

Key Takeaways for Retail Cyber Resilience

  • Retailers are now prime targets for financially motivated cybercriminals due to their vast amounts of customer data, complex ecosystems, and operational urgency.
  • You can’t protect blindspots. Real-time asset visibility is the foundation of effective cyber defense.
  • Flat networks are dangerous. Segment environments to prevent attackers from moving laterally across systems
  • Third-party risk is retail’s blind spot. Because of the interconnections between your suppliers, cloud services, and POS vendors, all expand your attack surface and introduce new attack vectors.
  • Cyber exposure management and security solve for today’s risk by delivering continuous, prioritized, and automated protection.
  • Adopting a proactive strategy that takes into consideration real world attack vectors, so you can protect what matters.

The Retail Store of the Future Has Infinitely More Attack Pathways

Why Retail? Understanding the Target

Retail has always been an attractive target for cybercriminals and the reasons aren’t hard to understand. At the core, retailers sit on a goldmine of data. Every day, they collect and process sensitive personal information, credit card data, loyalty account details, and employee records across millions of transactions. For attackers, this makes the industry not only lucrative but also highly scalable. A single breach can expose tens of thousands, if not millions, of data points that can be monetized instantly on the dark web.

But it’s not just about data. The structure of modern retail operations adds to the vulnerability. With sprawling digital ecosystems—ranging from online storefronts and mobile apps to in-store POS systems and backend inventory platforms, retailers often find themselves juggling a wide array of technologies, many of which were never designed with security for the litany of attacks we are seeing today. Add in interconnections of third-party vendors, cloud services, and logistics platforms, and you’ve got an expansive, fragmented attack surface that can be difficult to monitor and defend.

Retailers and associated supply chain partners operate under constant pressure to deliver seamless, always-on customer experiences. Operational resiliency is paramount especially during peak seasons like Black Friday or the holidays. That urgency often translates into fast-tracked IT rollouts, postponed security updates, or shortcuts in incident response readiness. And all of which can create windows of opportunity for attackers to strike. The combination of high reward and (perceived) lower resistance makes the retail industry a preferred hunting ground for financially motivated threat actors.

Immediate Actions Retailers Should Take Today

If you’re a retail CISO, CIO, or IT security leader, these are the non-negotiables you can act on now:

1. Conduct a Full Asset Inventory

Blindspots that obscure the deep visibility and situational awareness across your digital footprint is a crucial first step. Use cyber exposure management and security tools to discover and understand all connected assets across your environment, including shadow IT, unmanaged devices, and legacy systems. Include stores, warehouses, corporate offices, and cloud environments.

2. Assess for Known Vulnerabilities

Once your assets are mapped, immediately scan for known vulnerabilities, especially in third-party software used industry-wide. While the article doesn’t confirm a shared software flaw, it remains a possibility. Identify, deduplicate, contextualize, prioritize, assign and mitigate vulnerable systems and areas of concern without delay.

3. Segment Your Network

Flat networks are a hacker’s dream. Implement strong segmentation between customer-facing systems, payment processing environments (PCI), and back-office functions. If one area is breached, segmentation can limit the blast radius by eliminating attack proliferation.

4. Monitor for Indicators of Compromise (IoCs)

Threat intelligence teams, (such as Armis Labs and others)  are likely monitoring the threat actors behind these attacks. Integrate threat feeds into your SIEM or XDR platform and implement compensating controls.  Tune detections to look for their known tactics, techniques, and procedures (TTPs).

5. Revisit Ransomware and Incident Response Playbooks

Do you have a clear, tested plan in place for ransomware? Can you isolate affected systems within minutes? Have you run a tabletop exercise in the last 90 days? These are the operational muscle groups that must be flexed and constantly refined before an attack occurs.

Medium-Term Strategy: Rethinking Cyber Exposure in Retail

Immediate actions are vital, but they are just the beginning. Retailers must shift from reactive cybersecurity to proactive cyber exposure management; a modern approach that continuously identifies, assesses, prioritizes, and mitigates threats across the entire digital environment.

Here’s how to get there:

1. Move from Periodic Audits to Continuous Visibility

Traditional security postures rely on quarterly scans or periodic audits. In today’s threat landscape, that’s like locking your front door once a week and hoping for the best. Retailers need continuous, real-time visibility into all assets, connections, and exposures.

2. Prioritize Risks Based on Business Impact

Not all vulnerabilities are equal. A critical flaw in a test system is not as urgent as a moderate vulnerability in your e-commerce gateway during peak holiday season. Exposure management platforms that prioritize risk based on asset criticality and exploitability are a must.

3. Secure the Entire Supply Chain

Retailers rely on a web of vendors, from logistics and marketing to payment processors and third-party developers. Every one of them is a potential attack vector. Conduct risk assessments and monitor your external attack surface for signs of compromise.

4. Integrate Cybersecurity into Store Operations

Don’t treat cybersecurity as an IT-only issue; it can include OT, IoT and even proprietary set ups. Empower and train frontline employees to be part of the security solution which may involve recognizing phishing attempts, enforcing strong password hygiene, and reporting anomalies. Equip every employee with clear escalation paths in the event of suspected compromise.

5. Leverage AI and Automation

Attackers are using AI to scale their operations. Retailers must do the same. From early warning technology to anomaly detection to automated patching and threat triage, AI-driven tools can drastically reduce dwell time and response lag.

The Bottom Line: Cyber Resilience is a Business Imperative

The wave of retail-targeted attacks is not an isolated event, it’s part of a broader trend of cybercriminals targeting high-value, data-rich industries with weak or fragmented defenses. Whether motivated by financial gain or simply chaos, these actors are highly organized and increasingly emboldened.

If you’re in retail and still viewing cybersecurity as a cost center, it’s time to shift your mindset. Cyber resilience is now a core part of business continuity, brand trust, and customer loyalty.

As the National Retail Federation rightly pointed out, many U.S. retailers have taken steps to harden their defenses over the past two years. But “many” is not “all.” And in a connected ecosystem, the weakest link can, and often does break the chain.

What Leaders Must Ask Themselves

As a retail leader, ask yourself the following:

  • Do I have real-time visibility into every asset and exposure in my environment?
  • If a breach occurred today, could we detect it in time; and would we be ready to respond?
  • Am I confident that every store, system, and supplier is secure?

If the answer to any of these is “no” or “I’m not sure,” it’s time to act. Because the hackers aren’t just knocking, they’re already inside.
