Manufacturing is the backbone of economies around the world—and its importance makes it a major target for cybercriminals. As more manufacturers embrace digital tools to improve efficiency, the risks of cyberattacks are increasing rapidly.
According to the 2024 IBM X-Force Threat Report, manufacturing has remained the most targeted industry for cyberattacks for three years running, with ransomware attacks leading the charge. In fact, more than 25% of global cyber incidents in the past year hit manufacturers, disrupting production, delaying shipping, and causing serious financial and reputational damage.
At MapleTronics, we work with many small and mid-sized manufacturers who are navigating these evolving threats. In this article, we’ll explore the key cyber risks facing manufacturers and outline six proven strategies to help you reduce your exposure and protect what matters most.
The Expanding Threat Landscape for Manufacturers
Cyberattacks in the manufacturing space are becoming more frequent—and more damaging. In just one example, a ransomware attack on MKS Instruments in 2023 led to over $200 million in losses, with ripple effects impacting partners like Applied Materials, which suffered an additional $250 million in damages. Other high-profile victims, such as Clorox and Brunswick Corporation, have experienced similar disruptions.
And those are just the incidents that make headlines. Hundreds more ransomware attacks go unreported each year, often affecting small and mid-sized manufacturers that lack the resources for advanced cybersecurity defenses.
6 Areas of Cyber Risk—and How to Address Them
1. Outdated or Unpatched Software
Many breaches stem from software that hasn't been updated with security patches. Often, these are known vulnerabilities that remain unfixed for months—or even years. Running unsupported software, like older versions of Windows, also puts your environment at risk.
2. Legacy Equipment
Aging operational technology (OT) systems can be a weak point. When devices reach end-of-life and are no longer supported by the manufacturer, they become easy targets for attackers.
3. Phishing and Social Engineering
Attackers are using increasingly convincing phishing tactics to gain access to your network. These emails can look like real invoices, HR communications, or login prompts. Once clicked, attackers may steal login credentials or install malware.
4. IoT Device Vulnerabilities
Connected devices bring automation and efficiency—but they also create more potential entry points. Manufacturing accounts for over 50% of IoT malware attacks, with thousands of new threats emerging weekly.
5. Weak Access Controls
Without strong access policies, attackers can use remote access tools or shared login credentials to breach systems. Networks without proper segmentation also allow threats to spread quickly once inside.
6. Poor Password Hygiene and Lack of MFA
Simple passwords and unprotected accounts remain a leading cause of breaches. Enabling multi-factor authentication (MFA) is a critical step in preventing unauthorized access.
Building a Stronger Cybersecurity Foundation
Even as threats grow more sophisticated, manufacturers have effective tools available to improve security posture. Here's where to start:
1. Conduct an Asset Inventory
Know exactly what technology and data you have—and where vulnerabilities may lie. This includes devices, software, users, and cloud assets.
2. Perform a Risk Assessment
Evaluate how your current security measures compare to industry benchmarks. Don’t forget to review your supply chain, which is often the weakest link in your cybersecurity defenses.
3. Implement Targeted Remediation
Based on your risk assessment, prioritize key actions like:
Enabling MFA and conditional access policies
Segmenting your network
Automating software patches
Deploying next-gen antivirus and endpoint protection
Monitoring your environment with SIEM tools
4. Build an Incident Response Plan
Prepare your team with a clear, tested plan for what to do in the event of a cyberattack. Include internal and external contacts, damage containment procedures, and communication guidelines.
5. Develop a Business Continuity & Disaster Recovery (BCDR) Strategy
A solid BCDR plan ensures you can maintain operations during a crisis, protect critical data, and recover quickly with minimal downtime.
6. Explore Cyber Insurance
More insurers now require proof of cybersecurity best practices before offering coverage. Strengthening your defenses not only protects your business—it could also reduce your premiums.
The Bottom Line for Manufacturers
Cyber threats aren’t slowing down, and manufacturers are increasingly in the crosshairs. But with the right strategy, you don’t need to be vulnerable. By focusing on core areas like patching, access controls, incident response, and employee awareness, you can take meaningful steps to protect your operations, your data, and your reputation.
