2026's critical threats—Lazarus IT Workers operation and AI-driven phishing—unite around a single vulnerability: trust abuse. Adversaries exploit human confidence and institutional relationships rather than pure technical exploits. AI amplifies social engineering at scale, making traditional perimeter-focused security insufficient. Key insight: The most dangerous attacks target organizational trust systems themselves, not infrastructure. Enterprises must shift from assuming trustworthiness to continuous verification of digital identities and source authenticity, particularly for high-value communications and vendor interactions.
