When Social Engineering Meets Ransomware: What Businesses Can Learn from the M&S Cyberattack

In April 2025, British retailer Marks & Spencer (M&S) was the latest high-profile victim of a sophisticated cyberattack. The attack combined social engineering with ransomware deployment, targeting not just systems, but also people and third-party relationships.

For business leaders, this incident is a powerful reminder: today’s cyber threats don’t just come through malicious code—they often arrive through a convincing voice, a believable email, or a trusted vendor.

Here’s what happened—and how a proactive cybersecurity solution like PC Matic Pro can help prevent attacks like this.

What Happened: A Breakdown of the M&S Breach

During a UK parliamentary hearing, M&S Chairman Archie Norman explained that attackers used impersonation tactics—a form of social engineering—to breach the company’s network. Here’s how it unfolded:

  • Initial Entry: On April 17, attackers posed as a legitimate person within M&S’s workforce. With accurate details in hand, they contacted a third-party IT support provider and convinced them to reset an employee’s password.
  • Third-Party Vulnerability: The support desk involved was Tata Consultancy Services, which handles help desk operations for M&S. The attackers likely tricked them into helping without realizing they were part of an attack.
  • Network Access and Ransomware Deployment: Once inside, the attackers deployed DragonForce ransomware, encrypting critical VMware ESXi servers and stealing approximately 150GB of data.
  • Double-Extortion Threat: The ransomware gang used a double-extortion model—demanding ransom not only to unlock systems but also to prevent stolen data from being leaked publicly.

M&S responded by shutting down its systems and involving cybersecurity experts. Whether a ransom was paid remains undisclosed, but the damage was significant.

Key Takeaways for Business Leaders

This incident highlights several crucial lessons for businesses of all sizes:

  • Humans are often the weakest link – especially when cybercriminals impersonate trusted people or vendors.
  • Third-party vendors can become your biggest vulnerability, especially in support or access-related roles.
  • Traditional antivirus solutions alone aren’t enough to stop sophisticated threats like these.

How PC Matic Pro Could Have Helped

PC Matic Pro offers a modern, layered approach to cybersecurity designed for businesses like M&S. Here’s how it can defend against threats like social engineering and ransomware:

Application Allowlisting: Stop Unknown Threats Cold

PC Matic Pro uses a default-deny approach through application allowlisting. Only known, trusted software is allowed to run—everything else is blocked by default.

Role-Based Access and Device Controls

PC Matic Pro helps reduce human error by enforcing strict access policies. IT admins can limit who can make system changes or reset credentials, protecting against internal abuse or external impersonation.

Patch Management & Vulnerability Protection

Outdated software creates backdoors for hackers. PC Matic Pro ensures your systems are always updated with automated patch management, which drastically reduces the attack surface.

Real-Time Monitoring & Remote Management

With a cloud-based management console, PC Matic Pro provides real-time visibility into all endpoints across your business. You can detect and respond to unusual behavior—such as suspicious logins, system changes, or file encryptions—before damage is done.

Secure, American-Made, and Non-Outsourced

PC Matic Pro is developed and supported entirely in the United States. That means no offshoring of sensitive support services—which reduces your exposure to third-party missteps like the one that allowed attackers to breach M&S.

Vendor Security Without the Guesswork

PC Matic Pro helps your business create zero-trust environments, especially with vendors and outside access points. Even if credentials are compromised, unapproved software can’t run—stopping the attack chain before it starts.

Final Thoughts: Prevention is Better Than Recovery

M&S’s story is a wake-up call. The cyberattack wasn’t just a technical failure—it was a breakdown in people, process, and technology. And it cost the company more than just downtime.

In a world of deepfakes, fake identities, and fast-moving ransomware groups, your business needs more than antivirus. You need a solution that can adapt, enforce strict rules, and stop threats before they ever get a chance to run.

PC Matic Pro offers that kind of protection—with zero-trust principles, allowlisting, and proactive defense built for today’s cyber climate.
