Why it matters
The lethal-trifecta framing gives defenders a simple design heuristic for preventing prompt-injection-driven data exfiltration in AI agents, but this item is primarily course-marketing with no new technical depth.
A YouTube short from Practical DevSecOps explains the "lethal trifecta" for AI agents — access to private data, exposure to untrusted content, and a way to send data out — noting that combining all three in one agent lets a single prompt injection exfiltrate data. The clip, promoting the Certified Agentic AI Security Expert course, credits the term to Simon Willison (2025) and recommends removing at least one of the three legs in every workflow.
