Marks & Spencer (M&S) has terminated its contract with Tata Consultancy Services (TCS), a major Indian IT outsourcing firm, following a cyber attack that resulted in an estimated £300 million loss for the retailer. The decision comes shortly after M&S experienced a significant breach attributed to hackers from the group Scattered Spider, who exploited social engineering tactics to gain access to sensitive systems. Despite TCS’s denial of responsibility, the swift cancellation of the deal raises concerns about the adequacy of third-party security measures. This incident underscores the growing importance of cybersecurity in multinational operations and reflects on the need for robust defense strategies in the digital landscape, particularly as Indian firms continue to play a vital role in global IT services.
