What Happened?
A quarterly threat report from a major industrial cybersecurity firm indicates a 50% increase in cyberattacks targeting Operational Technology (OT) systems within the manufacturing sector during Q3 2025 compared to the previous quarter. Ransomware remains the dominant threat.
Business Impact
Attacks on OT systems can halt production lines, damage expensive machinery, compromise product quality, and potentially create unsafe working conditions. The financial impact of downtime in manufacturing is often immediate and substantial.
Why It Happened
Increased connectivity between IT and OT networks (IT/OT convergence), coupled with legacy OT systems lacking modern security controls, creates a fertile ground for attackers. Ransomware groups specifically target manufacturers due to the high cost of operational disruption.
Recommended Executive Action
Prioritize investments in OT visibility and security monitoring solutions. Ensure strict network segmentation between IT and OT environments using firewalls and demilitarized zones (DMZs). Develop and regularly test OT-specific incident response plans.
