Certified - AI Security Audio Course

This episode examines indirect and cross-domain prompt injections, which expand the attack surface by embedding malicious instructions in external sources such as documents, websites, or email content. Unlike direct injection, where the attacker provides inputs to the model directly, these threats exploit retrieval or integration features that feed information into the AI system automatically. Learners preparing for certification exams must understand the mechanics of these attacks, which occur when contextual data bypasses normal user input validation and reaches the model unchecked. The relevance lies in recognizing how indirect vectors can compromise confidentiality, integrity, and availability in AI environments, and why they present challenges that differ from classical injection risks.

The applied discussion highlights scenarios such as a retrieval-augmented generation pipeline that fetches poisoned documents or a plugin that receives hidden instructions from a web source. Best practices include validating all retrieved data, implementing layered content filters, and designing workflows with isolation boundaries between model prompts and external data. Troubleshooting considerations emphasize how reliance on untrusted content sources creates cascading failures that are difficult to diagnose. For exam preparation, candidates must be able to articulate both the theoretical definitions and the operational defenses, making indirect prompt injection an essential area of study for AI security professionals.
