Cybersecurity and Ransomware in the Structural Steel Industry: What to Watch For and How to Prevent Attacks

29 Apr 2025

By Colleen Blackmore-Doucette, President

In an age where digital technology is central to operations, the structural steel industry is not immune to cyber threats. From CAD drawings to supply chain logistics, nearly every aspect of a modern steel fabrication business involves data. Unfortunately, this makes the industry an increasingly attractive target for cybercriminals—particularly those deploying ransomware.

What Is Ransomware?

Ransomware is a type of malicious software that encrypts a victim’s files or systems, effectively locking users out until a ransom is paid. In many cases, even paying the ransom does not guarantee full data recovery or future protection. Structural steel companies—like many in the construction and manufacturing sectors—are often vulnerable due to limited IT infrastructure and a reliance on legacy systems.

Why the Structural Steel Industry Is at Risk

  1. Legacy Systems and Equipment
    Older machinery and software often lack modern security features. These systems can be easy entry points for cyber attackers.
  2. High-Value Intellectual Property
    Shop drawings, 3D models, and engineering documents are valuable. If compromised, they can delay projects or be sold to competitors.
  3. Time-Sensitive Operations
    Construction timelines are strict. Attackers know that a disruption could cost millions, making companies more likely to pay to resolve issues quickly.
  4. Third-Party Vulnerabilities
    Partnerships with general contractors, vendors, and logistics providers create an interconnected ecosystem. One weak link can expose everyone in the chain.

Warning Signs of a Cyber Threat

  • Unusual Account Activity: Logins from unknown IPs or irregular hours.
  • Slow or Non-Responsive Systems: Especially when accompanied by unfamiliar processes running in the background.
  • Ransom Notes or Pop-Ups: Often the first clear sign of ransomware.
  • Unauthorized File Access: Changes to sensitive files or missing data.
  • Unexplained Network Traffic: Especially to countries or IP ranges outside of your regular business scope.

How to Prevent Cyber Attacks

  1. Employee Training
    Human error is one of the leading causes of breaches. Regularly train staff to recognize phishing emails, suspicious links, and best practices for password security.
  2. Use Multi-Factor Authentication (MFA)
    Implement MFA for all critical systems. Even if credentials are stolen, MFA can block unauthorized access.
  3. Back Up Your Data Regularly
    Maintain secure, offline backups of key data. Test your backups periodically to ensure they can be restored quickly.
  4. Update and Patch Systems
    Regularly update software and firmware on all computers, machinery, and networked equipment to close known vulnerabilities.
  5. Install Endpoint Protection
    Invest in antivirus and anti-malware tools for all devices, including those used on the shop floor.
  6. Secure Your Network
    Use firewalls, network segmentation, and VPNs. Limit access to sensitive information based on roles and responsibilities.
  7. Develop an Incident Response Plan
    Have a documented plan for responding to cyberattacks. Know who to call, what to isolate, and how to communicate with stakeholders.

The structural steel industry is increasingly dependent on digital tools and workflows. With that dependency comes new risks. Proactively investing in cybersecurity isn’t just an IT issue—it’s a business continuity imperative.

Don’t wait for a breach to highlight your vulnerabilities. Start taking action today to protect your systems, your people, and your projects.
