Attack Chains, Not Just Attack Surfaces: Why Testing Individual Techniques Misses the Point

Introduction Security teams have gotten pretty good at testing against what can hurt them. Can this EDR agent catch this payload? Will my organization fail the phishing simulation? Does this SIEM rule fire on this particular technique? And, in more mature organizations, this testing happens continuously rather than as a one-off exercise. But no matter how much you validate against these

The article argues that security testing should focus on complete attack chains rather than isolated techniques, because point-in-time validation can miss how multiple steps combine into a real compromise. Based on the title and summary, the report is about defensive security methodology rather than a specific AI incident. RealGround implication: organizations using AI agents or automated workflows should test end-to-end abuse paths, not just single prompt or policy failures, because chained actions can create business-logic risk even when individual controls look effective.
