Generative AI Is Erasing Behavioral Tells, Weakening Behavior-Only Detection, Proofpoint Reports
Generative artificial intelligence (AI) is producing phishing emails with improved linguistic quality and personalization, making them harder to detect through behavioral patterns that email filters have historically relied on. Proofpoint demonstrated this trend at its Protect 2026 conference, showing how AI-generated messages now lack the telltale awkwardness and generic templates that once exposed malicious emails.
Why it matters: Email security teams and organizations using behavior-based detection face reduced effectiveness of traditional filtering methods, requiring evaluation of supplementary detection techniques to maintain phishing prevention.
