Your AI API Supply Chain Has a Security Blindspot — Here's How to Fix It When we talk about AI security, the conversation almost always goes to the model layer: prompt injection, jailbreaking, output manipulation. But there's a quieter, more dangerous attack surface hiding in plain sight — the infrastructure layer between your application and your AI providers. And it's already been exploited. Repeatedly. The Problem: You're Securing the Wrong Layer Here's a thought experiment. Your production app calls OpenAI, Anthropic, and Gemini through an AI gateway.

Let's look at what actually happened in 2026. Blindspot #1: Dependency Bloat = Attack Surface Bloat In March 2026, the TeamPCP threat group executed one of the most sophisticated supply chain attacks in Python history.…
