Security through obscurity is dead, and AI delivered the fatal blow

THE AI ANGLE
Accelerating vulnerability discovery and exploit generation across obscure systems while failing to produce reliable defensive patches

AI agents are rendering 'security through obscurity' obsolete by uncovering vulnerabilities in legacy code, open-source libraries, and industrial control systems while enabling attackers to rapidly craft exploits. Meanwhile, AI-driven remediation lags behind, with studies showing automated patches fail to resolve flaws or introduce new vulnerabilities more than half the time. This shift emphasizes to computing faculty that obscure implementations cannot substitute for robust architecture, and that defensive engineering must prioritize upstream process improvements over reactive patching.

THE TEACHING ANGLE
Students can examine the defensive asymmetry highlighted by AI's high competence in discovering vulnerabilities and reverse-engineering exploits versus its 26 to 56 percent failure-prone track record in generating functional patches.
