In recent weeks, the UK retail sector has faced a series of significant cyber attacks, highlighting the urgent need for businesses of all sizes to strengthen their cybersecurity measures. Most recently, retail giants North Face and Cartier reported data theft that included customer names and email address.   

Notably, Marks and Spencer experienced a sophisticated cyberattack that disrupted online clothing sales and contactless payments, leading to an estimated £300 million hit to operating profits.  

While these cases involve large retailers, they show that cybercriminals are targeting the entire retail ecosystem. Smaller businesses, often with fewer resources and weaker defences, can be even more vulnerable. That’s why it’s critical for all retailers, regardless of size, to take proactive steps in protecting their business from the growing threat of cyber attacks.  

 

 

The Ripple Effect: Consumer Trust and Behaviour  

Recent cyber incidents haven’t just disrupted the day-to-day operations of affected companies; they’ve also sparked broader conversations about trust. More and more, consumers are pausing before sharing their personal or payment details, especially with brands they feel might be exposed to cyber risks. That hesitation is shaping how people choose where, and with whom, to shop.  

And it’s no wonder, given the current climate. The retail sector is seeing a sharp 52% rise in cyber vulnerabilities year-over-year. Each new breach adds to the growing sense of uncertainty and reminds us all how crucial it is to strengthen our digital foundations. It's a collective challenge—one that calls for fresh thinking and shared solutions.  

Take Marks and Spencer, for example. A recent survey of over 500 respondents found that consumer willingness to recommend the brand dropped from 87% before a cyber incident to 73% after. That’s a 14% decline in brand advocacy—real numbers that point to shifting perceptions and the vital importance of trust in today’s market.  

But here’s the good news: this is a pivotal moment for innovation and collaboration. By listening to consumers, embracing smarter security practices and reimagining digital relationships, retailers have the chance to not only rebuild confidence but also lead the way in a more resilient and customer-centric future.  

 

 

Lessons from the Frontlines: Cyber Security Attacks in Retail 

These incidents, while challenging, offer valuable insights into how different businesses are responding, and adapting, in real time.  

Marks and Spencer (M&S) found itself at the centre of one of the more high-profile attacks. The breach—traced back to human error from a third-party provider—did more than disrupt services like online clothing sales and contactless payments. It’s projected to result in a £300 million hit to operating profits and has triggered a class action lawsuit following the exposure of customer data.  

M&S is still in recovery mode, with full restoration expected by July 2025. Their experience underscores how third-party relationships can become critical points of vulnerability—and why investing in broader cyber awareness across an entire network is so essential.  

Co-op, on the other hand, offers a glimpse of what swift, decisive action can look like. When suspicious activity was detected, the company took the bold step of taking systems offline—effectively stopping the attack in its tracks before ransomware could be deployed. While some customer data was still compromised, the damage was contained. 

Harrods, a name synonymous with luxury, wasn’t immune either. The retailer restricted internet access at its sites after detecting unauthorised access attempts, a move that helped limit the potential damage. Though its flagship store remained open, the incident served as a wake-up call: even the most prestigious brands are not beyond reach, and reputation alone isn't a defence against cyber risk.  

And it’s not just UK retailers feeling the heat. Global names like Adidas, Victoria’s Secret, North Face and Cartier have all reported cyber incidents in recent months. North Face disclosed a "small-scale" breach in April, while Cartier confirmed that an unauthorised party had briefly accessed its systems. In both cases, customer names and email addresses were compromised—fortunately, no financial information was affected.  

What’s especially concerning is the speed and coordination behind these attacks. In many cases (including the breach tied to hacker group Scattered Spider) multiple retailers were targeted within days of each other. It paints a clear picture: these aren’t isolated events. They’re part of a broader, fast-evolving threat that demands both vigilance and collaboration.  

 

 

 

 

Building a Cyber-Resilient Retail Business  

1. Keep Software Updated—Always  

Cybercriminals often exploit outdated software. Regular updates and security patches are one of the simplest yet most effective ways to close those doors before they’re pried open.  

Action Point:  

Set up automatic updates wherever possible and establish a monthly patching schedule to ensure nothing slips through the cracks.  

  

2. Embrace Multi-Factor Authentication (MFA)  

MFA adds a critical layer of protection by requiring more than just a password to access systems. It's one of the easiest wins in cybersecurity.  

Action Point:  

Start with critical systems—email, payroll, POS—and expand gradually. Encourage staff and partners to use MFA on personal accounts too.  

  

3. Empower Employees Through Training  

People are your first line of defence—and your biggest potential vulnerability. With cyber attacks often starting with a single click, awareness is everything.  

Action Point:  

Host regular training sessions (quarterly is a great goal), run phishing simulations, and keep the conversation going with friendly reminders and visual guides.  

  

4. Back Up Your Data—And Then Back It Up Again  

Backing up critical data ensures that even if an attack succeeds, your business doesn’t grind to a halt.  

Action Point:  

Automate daily backups, store them offsite or in the cloud, and test your recovery process regularly to make sure it actually works when it matters. Cloud backup services, such as Google Workspace or Microsoft OneDrive, often include secure storage that automatically protects your data without you needing to lift a finger. 

 

 

5. Build (and Rehearse) an Incident Response Plan  

Knowing what to do before something happens is key. A solid incident response plan helps you react quickly and effectively when under pressure.  

Action Point:  

Document step-by-step procedures, assign clear roles, and run mock drills at least twice a year. The goal: make responding to a breach second nature.  

  

6. Vet Your Vendors (Yes, All of Them)  

Third-party vendors can be your weakest link. Even the most secure retailer is only as safe as its least secure partner.  

Action Point:  

Create a checklist of cybersecurity standards for all suppliers, request regular compliance reports, and include security obligations in contracts.  

 

 

7. Explore Cyber Insurance as a Safety Net  

While prevention is the priority, it’s smart to prepare for the worst. Cyber insurance can help cover costs like legal fees, recovery expenses, and even PR efforts.  

Action Point:  

Speak with an insurance broker who specialises in digital risk to find a policy that fits your business size, sector and risk profile.  

 

 

 

Cybersecurity on a Budget: Practical Steps for Indie Retailers  

Protecting your business doesn’t have to mean breaking the bank. With the right mix of affordable tools, smart planning and a bit of community know-how, you can build strong digital defences without a big-business budget.  

 

 

Start with the essentials  

There are plenty of free or low-cost tools that can make a world of difference:  

Password managers (like Bitwarden or LastPass) help your team create and store strong, unique passwords securely.  

Antivirus and anti-malware software can flag suspicious activity before it becomes a full-blown problem—check out trusted names like Avast, Malwarebytes, or Sophos Home.  

 

 

Consider calling in the professionals (when needed)  

If managing cybersecurity feels overwhelming, you’re not alone. That’s where Managed Service Providers (MSPs) come in. These are external experts you can call on when you need a helping hand—whether it’s for setting up secure systems, responding to an incident, or just getting advice. Many offer pay-as-you-go or flexible packages designed for small businesses.  

 

 

Prioritise what matters most  

When every pound counts, it’s helpful to separate your “must-haves” from your “nice-to-haves”.

Must-haves might include regular software updates, MFA (multi-factor authentication), and secure backups.  

Nice-to-haves could be more advanced tools like real-time threat monitoring or penetration testing—great to explore when your budget allows.  

 

The key takeaway? Even small steps can offer big protection. It’s all about being intentional, resourceful and staying connected to the wider retail community.
