Marks & Spencer (M&S) suffered a **major cyber-attack in April**, forcing the company to **halt online orders for nearly seven weeks**. The disruption led to a **20% decline in clothing sales** over a four-week period ending 25 May, causing significant financial losses and competitive setbacks against rivals like Next, Zara, and H&M. The attack disrupted core e-commerce operations, directly impacting revenue streams and customer trust. While the article does not specify data theft, the prolonged outage suggests a **targeted disruption of business-critical systems**, likely involving operational technology or payment processing infrastructure. The incident underscores vulnerabilities in digital supply chains, particularly as cybercriminals leverage increasingly sophisticated methods, including AI-driven attacks. The financial and reputational damage aligns with broader industry warnings about outdated systems (e.g., unpatched software like Windows 7) exacerbating risks in smart, interconnected environments.
