Cyber Attacks Continue to Pose Major Threat to Manufacturing Sector

Cybersecurity is no longer just an IT concern — it’s a business continuity issue. For manufacturers, the stakes are especially high. With increasing reliance on connected equipment, automation, and supply chain integrations, even a minor security breach can disrupt production, halt shipments, and compromise sensitive intellectual property.

Unfortunately, manufacturers continue to experience cyber attacks, often due to legacy technology. IBM’s 2025 X-Force Threat Intelligence Index finds that manufacturing is the top targeted industry for cyberattacks — for the fourth consecutive year. As such, manufacturers cannot afford to delay a review of their cybersecurity protocols.

Why Manufacturers are Prime Targets for Cyber Attacks

Unlike many industries, manufacturers operate within unique risk profiles. Legacy manufacturing equipment was designed with efficiency in mind, not security. Supply chain reliance also creates distinct risks. A single breach in a manufacturer’s vendor network can send ripple effects through systems, halting production or compromising deliveries.

Ultimately, the smallest cyber-related disruptions can translate to significant lost revenue and strained client relationships for manufacturers.

Key Cybersecurity Risks in Manufacturing

There are a variety of common threats employers in the manufacturing space should be aware of, including ransomware attacks, social engineering fraud, phishing attempts, and third-party breaches.

Ransomware attacks are increasingly prevalent, wherein hackers encrypt data or lock down equipment and demand payment for restoration. Manufacturing had the highest number of ransomware cases in 2024, according to IBM’s 2025 X-Force Threat Intelligence Index.

Social engineering fraud is another growing concern, where attackers manipulate employees into transferring funds, sharing credentials, or granting access under the guise of legitimate requests. Unlike purely technical attacks, social engineering exploits human trust — making employee awareness and verification protocols critical.

In addition, phishing  attempts and third-party breaches are on the rise. Employees may be tricked into clicking malicious links, unintentionally opening the door to cyber attackers, and vendors or contractors with access to systems may introduce vulnerabilities.

For example, APT37, known as “Reaper,” is a North Korean hacking group whose focus on cyber-espionage has expanded from South Korean targets to manufacturing industries. Generally, their attacks begin with phishing emails that appear legitimate and contain malicious links or attachments. Users who interact with these emails inadvertently install malware on their systems.

How Manufacturers Can Enhance Cybersecurity Now

Strengthening your cybersecurity strategy requires a proactive, multi-faceted approach. Manufacturers should audit systems, implement controls, and invest in cyber-specific tools and products.

Audit Systems and Vendors

Audit your operational technology and information technology systems to identify outdated equipment, unpatched software, and weak points in your production environment. Review your HR technology systems to ensure employee records and sensitive information are stored securely. Don’t forget to assess your vendors’ cybersecurity measures to ensure they meet your standards.

Implement Controls and Training

Limit system access based on employee roles and regularly review permissions and train your workforce to combat cyber attacks. Employees should understand how to recognize phishing attempts, handle sensitive data, and report suspicious activity.

Invest in Security Tools and Services

Early detection of unusual activity can prevent minor breaches from becoming full-scale crises. Consider investing in monitoring and detection tools — or leveraging a full-service IT solution — to help ensure 24x7x365 protection. At CBIZ, our managed IT services include tailored IT support and consistent security monitoring to help safeguard your organization from cyber attacks.

Having the proper insurance in place can also help manage financial fallout should an incident occur. Proactively secure cyber liability insurance to maximize your protection.

Develop Incident Response Plans

A clear protocol ensures that, if a breach occurs, downtime and losses are minimized. Effective response plans should outline roles and responsibilities, communication procedures, and escalation pathways. Regular testing and tabletop exercises also help ensure employees know how to respond quickly and confidently in the event of an attack.

Connect With CBIZ to Strengthen Your Cybersecurity

While protecting operations is essential, strong cybersecurity can also differentiate manufacturers in the marketplace. Clients and supply chain partners are increasingly scrutinizing security practices, and manufacturers that demonstrate robust protocols are likely to stand out as reliable partners.
