Why Strong DMARC Policies Are Critical In The Age Of AI Driven Impersonation
Proofpoint, March 27,2026
Artificial intelligence has dramatically changed the economics of cybercrime. What once required time, research, and human effort can now be automated, scaled, and optimized by generative AI (GenAI).
Nowhere is this shift more evident and more dangerous than in email‑based impersonation attacks. With AI‑powered tools, attackers can generate highly convincing emails in seconds, mimicking tone, writing style, and contextual awareness with unsettling accuracy.
At the same time, emerging 'vibe coding' tools are lowering the barrier to building malicious infrastructure. Attackers can rapidly generate realistic phishing websites designed to harvest credentials or distribute malware, without traditional development expertise.
