DHS Secretary Mullin: No Evidence Incident Was Cyberattack or AI-Caused

The signal here is procedural, not conclusive: DHS is publicly separating what it has found from what it is still testing, which keeps both the cyber and AI explanations formally open even as it pushes back on early speculation. That distinction matters for operators and insurers exposed to AI-linked incident narratives, since attribution drives liability and disclosure decisions long before any technical consensus forms. Whether the review narrows to a conventional cause or keeps the cyber option live is the open question worth tracking.
