Marks & Spencer (M&S), one of the largest and most established retailers in the United Kingdom, has confirmed that a highly targeted social engineering operation triggered the ransomware attack in April 2025. This breach, which is associated with DragonForce ransomware, points to a disturbing trend in the cybersecurity landscape, namely that human manipulations are increasingly becoming a way to access large-scale digital networks.

Several preliminary findings suggest that the attackers deceived individuals within or connected to the organisation, possibly by posing as trusted employees or partners, to gain unauthorised access to M&S's internal systems. Once they gained access, the attackers deployed ransomware that crippled the organisation's operations and led to the theft of approximately 150 GB of sensitive information.

It is important to note that not only did the attack disrupt critical business functions, but it also exposed the weakness in the company's dependence on third-party vendors, whose vulnerabilities may have contributed to the intrusion. While the company is actively regaining control of its infrastructure as a result of the breach, the incident is a clear warning to organisations across many sectors about the growing threat of social engineering as well as the urgent need for more robust human-centred cybersecurity defences to protect against it.

A public hearing was held on July 8, held at Parliament, in which Archie Norman, Chairman of Marks & Spencer (M&S), gave further insight into the cyberattack in April 2025 that disrupted the retailer's operations. Norman acknowledged that the incident was indeed a ransomware attack, but he declined to divulge whether the company had negotiated anything with the threat actors involved or negotiated a financial settlement. 

According to Norman, who addressed the Business and Trade Sub-Committee on Economic Security, Arms and Export Controls at the UK Parliament, the experience was one of the most disruptive and complex crises he had experienced in his considerable career in business and retail before this one.

In addition, the tactic represents a growing trend in cybercrime in which attackers exploit the trust that large, distributed organisations place in their internal and external vendors to gain access to their networks. The perpetrators were able to manipulate routine IT processes, such as password resets, and then move laterally within the network, setting the stage for a wider deployment of ransomware.

There is an important lesson to be learned from the incident regarding the importance of stringent verification procedures when working with external partners who can become weak links in your security chain, particularly when engaging with external partners. As reported in the Financial Times in May, Tata Consultancy Services (TCS) allegedly initiated an internal investigation to determine whether the company unknowingly played a role in the cyberattack on Marks & Spencer by facilitating the cyberattack.

In the case of TCS, which provides M&S's help desk support, it has been suspected that the threat actors have manipulated the company into resetting the password of an employee, enabling the attackers to gain access to the retailer's internal network. The threat actors are alleged to have done this through the manipulation of TCS. This potential compromise highlights the broader risks associated with outsourcing IT operations and the increasing reliance on third parties to handle critical business functions, as well. 

While speculation continues to abound on the possible financial resolution of the ransomware attack, Marks & Spencer has chosen not to disclose whether they have made a ransom payment in the first place. Chairman Archie Norman's testimony made reference to professional ransomware negotiation firms in his testimony. These firms, which are usually specialised intermediaries that assist victim organisations to engage threat actors and facilitate cryptocurrency payments, typically using Bitcoin, are often used by these firms to help victims resolve these threats.

In response to a direct question regarding whether M&S had met the ransom demand, Norman declined to provide a definitive answer. He stated that the company had "not discussed those details publicly" as they believed it was not in the public interest to do so. However, he emphasised that the National Crime Agency (NCA) and other law enforcement authorities had been notified of the full extent of the investigation.

Many experts on the subject of cybersecurity warn that ransomware groups rarely cease extortion efforts without compensation. Because the stolen data has not yet been disclosed publicly, experts believe a ransom might have been paid quietly or negotiations may still be ongoing with the attackers.

Regardless of the outcome of the M&S breach, it serves as a sobering reminder that cybersecurity failures have evolved beyond technical vulnerabilities and are now a result of failures across people, processes, and technological safeguards as well. Despite the rapid evolution of the threat environment in today's world, traditional security tools such as antivirus software are no longer sufficient to deal with the growing number of malware groups that are becoming increasingly agile.

It is imperative that businesses adopt adaptive security architectures that are policy-driven and capable of detecting and neutralising threats before they escalate. In light of the M&S incident, there is an urgent need to develop an approach to cyber resilience that anticipates human error, strengthens digital ecosystems, and minimises the operational and reputational costs associated with an attack.

 In this era of cyber-threats, an incident such as Marks & Spencer's ransomware is often referred to as a case study since it exemplifies how human nature has become as vital as technological defences in combating cyber-attacks.

In an era where organisations are accelerating their digital transformation and increasingly relying on distributed teams, cloud infrastructure, and third-party vendors, this attack reinforces the importance of implementing an integrated cybersecurity strategy that focuses on more than just system hardening; it also emphasises employee awareness, vendor accountability, and continuous risk management.

The most effective way for a company to protect itself is to adopt a proactive, intelligence-driven security posture rather than a reactive, reactive approach; to embed cybersecurity into every aspect of the business, governance, and culture. The deployment of behavioural analytics, third-party audits of identities, and enhancement of identity verifications are no longer optional components of modern cybersecurity frameworks, but rather essential components.

 In the face of increasing threats that are both swift and complex, resilience is not only a one-time fix but a continuous discipline that must be engineered. The M&S breach is more than just a cautionary tale. It is a call to action for enterprises to redesign their security strategies so that they can remain competitive, agile, and forward-thinking.
