In the world of cyber-physical systems (CPS), we often talk about critical infrastructure as a regional concern: the power grid in one state, the water utility in another. But the geopolitical reality of 2026 has made it clear that some infrastructure is so central to the global economy that its protection is a matter of international stability.
Hacktivist collectives and nation-state actors have recently shown that their targets are not just limited to data theft and IT-centric disruptions. They’re attacking water and power facilities, manufacturing, supply chains, medical technology, and hospitals. And while kinetic conflicts escalate worldwide, these attacks are signaling that the next theater of conflict isn't just physical, it is operational. This is another dramatic escalation that has quickly risen from a concern of private companies into a national security issue, with serious implications that threaten not only global supply chains, but the very foundation of living in a world where the line between digital and physical systems continues to grow thinner.
The Semiconductor Risk: A Global Single Point of Failure
The global economy runs on semiconductors, serving as the foundational hardware that powers the CPS behind modern logistics and global supply chains. An attack on a semiconductor facility's operational technology (OT), no matter where it is located, is, by extension, an attack on the global supply chain. If the OT systems governing the cooling, chemical delivery, or power filtration of a major plants are compromised, the implications stretch far and wide:
Global Lead Times Skyrocket
Semiconductors are essential for the intelligent transportation systems, autonomous vehicles, and supply chain monitoring systems (such as RFID and IoT sensors) that keep goods moving efficiently. An intentional OT disruption at a semiconductor fabrication plant would severely limit the production of these chips, causing the manufacturing lines that rely on them to come to a grinding halt.
Cascading Economic Failures
Modern supply chains are highly integrated and built to emphasize efficiency over resilience; a disruption in the digital systems that produce their foundational components can affect the flow of goods almost instantaneously. Much like the 2024 ransomware attack on the battery manufacturer Varta, which forced multiple facilities worldwide offline for weeks and caused cascading failures, compromising a semiconductor fabrication plant would trigger devastating ripple effects across the automotive, aerospace, medical, and AI sectors.
Severe Real-World Consequences
The stakes go well beyond data loss or temporary technology shortages. Without the chips required to run predictive maintenance platforms or advanced logistics sensors, the flow of essential goods is threatened, meaning medication won't reach hospitals, fresh food could spoil in delayed shipments, and the complex web that powers our modern lives could stumble before we even realize it.
The New Threat Detection Playbook: Pre-positioning for Chaos
The nature of the threat has shifted. We are no longer just seeing smash-and-grab data breaches. Instead, sophisticated actors are focusing on pre-positioning efforts that often are precursors to kinetic warfare, such as infiltrating OT networks to gain unauthorized access. This is often the first step in a larger campaign aimed at sowing chaos, especially in times when political unrest is already elevated.
For a semiconductor fabrication plant, a power fluctuation of even a few milliseconds or a minor compromise in water purity can ruin an entire batch of wafers, potentially costing billions of dollars and months of lost production.
Building Resilience Through a CPS Protection Program
It’s virtually impossible to secure OT networks with legacy technology that was designed with IT in mind first. The current threat landscape has made the traditional air-gap defense irrelevant, and standard IT security solutions often fail to understand the proprietary protocols and safety requirements of OT environments.
This is why a CPS protection program is no longer optional, it is a strategic imperative. Securing modern critical infrastructure such as semiconductor facilities requires a comprehensive, programmatic approach that addresses all necessary areas of the security lifecycle to keep critical operations safe and resilient. A holistic program covers the following foundational pillars:
Deep Visibility (The Foundation)
You cannot protect what you cannot see. A robust CPS program starts with an automated inventory of every CPS asset, understanding their device purpose, communication patterns, and other associated characteristics.
Risk & Vulnerability Management
In OT, you can’t always patch a legacy server conveniently and quickly without causing a potentially significant operational disruption. A CPS protection program identifies which vulnerabilities should be prioritized for the most protection based on business impact, allowing teams to prioritize compensatory controls where patches aren't an option.
Network Segmentation
In flat, unsegmented networks, attackers have an easy path to breach business-critical devices and move laterally across the environment. Effective network segmentation helps untangle the chaos of loose communication policies and imprecise segmentation. By demystifying network communications and segmenting the CPS network, organizations can establish strict policies, reduce their overall risk score, and implement ongoing alerts to catch irregularities if a device deviates from established baselines.
Secure Remote Access
Moving away from unmanaged VPNs is a good start, but traditional IT-centric solutions are ultimately not effective ways to protect remote access to CPS. Organizations need to implement a zero trust framework enhanced with privileged access management (PAM) capabilities. This minimizes the risk of unauthorized users while giving admins full visibility and control over all third-party and internal remote activity. With real-time session oversight, facilities can securely allow smooth, uninterrupted remote logins, cutting down on costly on-site visits, reducing mean time to repair (MTTR), and ensuring regulatory compliance.
Protecting Semiconductor Facilities with a Programmatic Approach
By taking a programmatic approach to cybersecurity, organizations can move from a reactive posture to a proactive, resilient one. With a CPS protection program tailor-made for the needs of unique semiconductor environments, Claroty provides exactly the kind of visibility needed to detect the quiet infiltrations of state actors and the controls to ensure that even under duress, the world’s most critical production lines keep moving.
The digital defense of the semiconductor supply chain starts with securing the cyber-physical systems that sustain it. It’s time to build a shield that is as advanced as the chips it protects.
