Indirect Prompt Injection and the Lethal Trifecta
Indirect prompt injection plants attacker instructions inside content an agent retrieves or reads (a web page, a PDF, a support ticket) so a benign user triggers an attack. The lethal trifecta is the combination that turns this into real damage: access to private data, exposure to untrusted content, and a channel to send data out. Applied AI interviews probe it because anyone building RAG or tool-using agents has to reason about blast radius, not just clever filters.
