Why it matters
Connectors that combine access to private data, untrusted content, and external communication create the exact conditions attackers exploit to exfiltrate data via indirect prompt injection, a growing risk as AI agents gain more integrations.
PromptArmor outlines a threat model for AI application 'connectors' (such as Confluence and Zendesk integrations), explaining how they expand the attack surface for indirect prompt injection along three pillars: untrusted external data intake, sensitive internal data intake, and downstream actions. The analysis maps these risks to Simon Willison's 'lethal trifecta,' illustrating how a customer support ticket carrying a prompt injection could manipulate an agent into leaking internal knowledge-base articles.
