: Adversaries now routinely use Large Language Models (LLMs) to craft hyper-personalized phishing and plausible deepfakes, achieving significantly higher compromise rates than traditional methods.

The global Critical Infrastructure Protection (CIP) Market is projected to reach approximately , driven by rising digitalization and the urgent need to secure interconnected assets. 1. The Evolving Threat Landscape in 2026

Critical Information Infrastructure (CII) refers to the computer resources, networks, and digital assets so vital that their incapacitation or destruction would have a debilitating impact on national security, the economy, public health, or safety. As we move further into 2026, these systems—ranging from electrical grids and water treatment plants to financial networks and telecommunications—are facing an unprecedented era of disruption.

: The objective has shifted from simple data theft to taking systems offline. Attack campaigns targeting CI surged by 87% in early 2025 .

Critical Information Infrastructures Security: Safeguarding the Backbone of Modern Society : Adversaries now routinely use Large Language Models

: Persistent actors like "Volt Typhoon" maintain long-term access inside infrastructure, using "living-off-the-land" (LOTL) techniques to stay undetected and ready for activation during a future crisis.

: Over 97% of identity-based attacks target password-based authentication. Attackers now use legitimate credentials to bridge the gap between enterprise IT and operational technology (OT). The Evolving Threat Landscape in 2026 Critical Information

Protecting CII is complicated by several inherent weaknesses in how these systems were built and maintained: Key competencies for critical infrastructure cyber-security
