AI gateway credential misuse
AI gateways concentrate model access, billing, and downstream identity. This guide explains the investigation problem when a credential may be shared, leaked, or resold, including what gateways preserve, what they replace, and which evidence can distinguish an operational change from misuse.
What makes gateway misuse hard to investigate?
A gateway receives one request and creates another. The upstream provider may see the gateway but not the downstream user, session, or client. Rate, IP, and model changes are useful clues, not attribution.
What should an operator do next?
Preserve the relevant time window, attach customer and deployment context, and make the smallest reversible response that contains credible risk. Record why a case opened so another investigator can reproduce the decision.
Where does this approach fail?
Behavioral metadata cannot identify intent or permission by itself. Legitimate launches, failover, automation, and registered relays can resemble misuse. Treat the output as a ranked investigation queue, then resolve authorization with stronger identity and reconciliation evidence.
Frequently asked questions
Should every unusual gateway pattern be blocked?
No. Use reversible controls and verification unless credential-state or identity evidence supports stronger action.
Does InferTrail read prompts or responses?
No. The investigation design uses provider-visible metadata and customer context, with content collection governed separately if a customer requires it.
What is the right first action?
Open a verification case, preserve evidence, and check credential state before making a destructive enforcement decision.
