Dangling DNA: The Most Overlooked Attack Surface In The AI Era
Akamai Technologies, Friday, January 16th, 2026
Today's organizations are focused on securing large language models (LLMs), mitigating prompt injection, and governing agentic browser behavior. But one of the most consequential artificial intelligence (AI)-era attack vectors is not directly related to AI models - it sits quietly inside your Domain Name System (DNS).
As AI agents increasingly rely on DNS and HTTP to navigate the web, they inherit decades-old security risks from these mature protocols. A forgotten DNS record pointing to an abandoned cloud resource can become a weapon: When attackers reclaim that resource, they gain control of a trusted subdomain that AI agents will thoughtlessly follow.
This blog post explains why dangling DNS is now a critical AI security threat and how platforms like Akamai DNS Posture Management help mitigate these risks.
