Introduction:
In a world increasingly reliant on digital infrastructure, cyberattacks are no longer a rarity—they’re a looming threat to even the most established businesses. When Marks & Spencer (M\&S), one of the UK’s most iconic retail brands, revealed it had suffered a massive cyberattack, speculation swirled about the source of the breach. Since TCS (Tata Consultancy Services) is a major technology provider to M\&S, it was naturally drawn into the narrative. But now, TCS has publicly spoken out to clarify its role—or lack thereof—in the crisis.

Tata Consultancy Services (TCS), India’s largest IT services company, has officially stated that none of its systems or personnel were compromised in the cyberattack that hit its client Marks & Spencer (M\&S). This incident, which resulted in significant customer data theft, marked a turning point in digital risk for the British retailer. Independent director Keki Mistry addressed the issue during TCS’s annual shareholder meeting, emphasizing that the company’s systems remained secure and unaffected, and its other clients were not impacted.
Mistry clarified that the ongoing investigation into the breach does not implicate TCS. Notably, TCS had previously secured a \$1 billion contract with M\&S in 2023, aimed at revamping the company’s outdated technology, including its supply chain systems and e-commerce platforms.
M\&S disclosed the breach in April, describing it as a “highly sophisticated and targeted” cyberattack. The company projected a staggering £300 million (\$403 million) hit to its operating profits due to service disruptions, particularly in its online business, which is expected to remain affected until at least July.
Though a Financial Times report noted TCS was conducting an internal review to ensure no linkage to the attack, initial findings show no breach on their end. Reports suggest the attack may have been conducted through a third-party vector, with cybercrime group DragonForce being named as a likely culprit.
M\&S acknowledged that online sales in segments such as fashion, home, and beauty were severely impacted by the forced shutdown of e-commerce services. However, the brand noted that physical stores remained operational and resilient.
What Undercode Say:
The TCS-M\&S incident is a textbook example of the cascading risk that comes with complex, interconnected digital ecosystems. Even when a company like TCS maintains airtight internal cybersecurity practices, associations with vulnerable clients can damage reputation by proximity. This is why the public denial and clarification from TCS are crucial—not just for shareholders but also for the broader tech outsourcing ecosystem.
The £300 million operating profit loss projected by M\&S is not merely a financial wound; it underscores a larger structural vulnerability in how traditional retailers handle digital transformation. The irony here is palpable: M\&S was in the middle of a modernization overhaul—intended to improve its digital resilience—when it fell prey to a breach. This points to either a delay in implementation or an exploited gap in the transitional process.
The mention of DragonForce raises the stakes further. As a well-known hacking group, its involvement suggests a deeper level of coordination and motivation behind the attack. This wasn’t a generic ransomware campaign—it was a targeted, deliberate strike on a legacy-heavy retailer transitioning to a new digital age.
From TCS’s perspective, this situation is a critical reputational stress test. With high-profile clients and billion-dollar contracts, their ability to maintain trust depends on transparency and proactivity. Their internal investigation—even if only precautionary—is a smart move to preempt finger-pointing and reassure future clients.
What we see here is not just a cybersecurity incident but a case study in digital trust. The digital supply chain is only as strong as its weakest third-party link. It’s not enough to secure internal systems; all external dependencies must be hardened too. Retailers, tech vendors, and even regulators must adopt a “zero-trust” approach across digital interfaces.
The fact that physical stores remained unaffected also reminds us that omnichannel strategies can offer resilience—but only if properly balanced. Overdependence on online channels without robust contingency plans can bring operations to a standstill when digital assets are compromised.
Ultimately, TCS dodged a bullet—but M\&S did not. This incident should be a wake-up call across industries that are accelerating digital overhauls. Investing in cybersecurity is no longer a checkbox in a transformation roadmap—it is the roadmap.
🔍 Fact Checker Results:
✅ TCS officially denied any system compromise via independent director Keki Mistry.
✅ M\&S estimated a £300 million (\$403 million) operating loss tied to the breach.
❌ No direct link between TCS and the hacker group DragonForce has been confirmed.
📊 Prediction:
With online disruptions expected to persist through July, M\&S will likely report underwhelming quarterly earnings. However, expect the company to expedite its digital modernization efforts and allocate more budget toward cybersecurity. TCS, on the other hand, will emerge relatively unscathed in this cycle, possibly even leveraging this event to market its security protocols as a selling point for future contracts. Retailers across Europe may now re-evaluate their digital outsourcing partnerships and push for stricter security audits.
