Harrods Data Breach Exposes 430,000 Customer Records in Third-Party Cyberattack

Harrods, the iconic London luxury department store, has confirmed a major data breach impacting approximately 430,000 customer records after a third-party supplier’s systems were compromised. The incident occurred in late September 2025, highlighting growing concerns about supply chain security in the UK’s retail sector.

What Happened: Details of the Harrods Breach

The breach resulted from a cyberattack targeting one of Harrods’ external service providers. Attackers accessed basic personal information from the supplier’s systems, not Harrods’ own infrastructure. Importantly, no payment information, account passwords, or order histories were exposed.

Only names, contact details, marketing preferences, loyalty card data, and co-branded partnership information were affected. Harrods began notifying customers and authorities within a week of discovery, stating they would not engage with the threat actors.

“We have been notified by one of our third-party providers that some Harrods e-commerce customers’ personal data has been taken from one of their systems,”: the company confirmed.

Scope and Nature of the Data Exposed

• 430,000 customer records affected
• Data exposed: Names, contact details, marketing preferences, loyalty program data
• Not exposed: Payment details, passwords, financial information, order histories

While Harrods describes the stolen information as largely “mundane,” security experts warn such details can still enable targeted phishing attempts or identity theft schemes. Source

Recent Cybersecurity Context

This marks Harrods’ second major cybersecurity event in 2025. In May, the retailer thwarted an attempted breach linked to the Scattered Spider hacking group, which also targeted Marks & Spencer and Co-op. Unlike that previous attempt, September’s breach exploited supply chain vulnerabilities rather than internal systems.

Public Reaction and Industry Implications

The breach has sparked concern across UK tech forums and social media, with customers expressing frustration over notification delays and demanding greater transparency. Many urge Harrods and other retailers to implement stricter vetting and ongoing security reviews of third-party suppliers.

Under UK and EU data protection laws, organizations must notify affected individuals and may face regulatory scrutiny, potential fines, and reputational damage if vendor oversight is found lacking. Source

What Customers Should Do

• Remain alert for suspicious emails or unsolicited contacts referencing Harrods or loyalty programs
• Monitor accounts for unusual activity and report suspected phishing attempts
• Contact Harrods customer support for guidance if you believe your data was affected
