Vertex AI 紅隊 導覽 (Platform 導覽)
Complete red team walkthrough for Google Vertex AI: testing prediction endpoints, 模型 Garden assessments, Feature Store probing, and exploiting Vertex AI 代理s and Extensions.
Vertex AI is Google 雲端's unified ML platform, providing access to Gemini models, open-source models through Model Garden, custom model hosting, Feature Store (for structured feature serving), Vertex AI Search (RAG), and Extensions (工具使用). Each component presents attack surfaces that differ from AWS and Azure equivalents due to GCP's IAM model and architecture choices.
Phase 1: IAM and Service Account Reconnaissance
GCP's IAM model uses project-level, folder-level, and organization-level policies. Vertex AI 權限 are grouped under the aiplatform.* IAM 權限.

Vertex AI prediction endpoints serve deployed models via REST and gRPC APIs. 測試 focuses on 輸入 validation, model manipulation, and 輸出 data leakage.

Model Garden provides access to hundreds of foundation models (open-source and proprietary). 安全 concerns include deploying models with known 漏洞, inadequate 安全 訓練, and misconfigured access.

Vertex AI Feature Store serves feature values for ML models. If feature definitions contain sensitive data (customer attributes, behavioral signals, financial metrics), the Feature Store becomes a data exfiltration target.

Vertex AI Extensions allow models to interact with external APIs and tools. Like Bedrock 代理, this creates tool abuse attack surfaces.
