The New AI Attack Surface: 3 AI Security Predictions for 2026

**AI security roadmap (2026): three imminent attack vectors.** The report forecasts three high-risk AI-native threats—(1) indirect injection/data poisoning where inputs to LLMs (RAG sources, documents, tool outputs) become executable instructions, (2) MCP/toolchain poisoning that deposits backdoors or malicious dependencies into AI-generated code, and (3) agent-to-agent taint propagation where trusted inter-agent communication enables lateral movement—illustrating enterprise scenarios, technical mechanisms, and a call to shift security focus to runtime protections, asset discovery, and validation of data and tool integrations.
