Tata Consultancy Services (TCS), a leading Indian IT services firm under the Tata Group umbrella, is reportedly investigating whether its systems played any role in the recent ransomware attack that disrupted operations at British retail giant Marks & Spencer (M&S). 

The cyberattack, which occurred in late April 2025, was initially described by M&S as a “cyber incident.” However, subsequent reports confirmed it to be a ransomware assault that severely affected both in-store and online operations. Key services such as contactless payments and Click and Collect were disabled, while online orders came to a standstill. 

Several internal systems were reportedly taken offline as a containment measure. The prolonged disruption, lasting several weeks, had a significant impact on M&S’s business. The company’s market capitalization is estimated to have dropped by £1 billion, and there are allegations that customer data may have been compromised in the breach. 

As M&S continues recovery efforts, TCS is conducting a thorough internal investigation to determine whether any part of its infrastructure might have been involved in the incident. TCS has long been a key technology partner for M&S, which adds urgency to the ongoing review. The attack has once again brought cybersecurity solutions into focus. 

Platforms like Keeper Security, known for their zero-knowledge encryption-based password managers and digital vaults, are gaining traction. Keeper offers features such as two-factor authentication, secure file storage, dark web monitoring, and real-time breach alerts—tools that are increasingly vital in defending against sophisticated cyber threats like ransomware.
