Detect Graphql Abuse
Detection and response methodology for GraphQL endpoint abuse - introspection and field-suggestion schema reconnaissance, batching and alias abuse to bypass rate limits and brute force login or OTP mutations, and depth and complexity attacks that exhaust the backend. Maps to MITRE ATT&CK T1190, with T1595, T1110, and T1499.003. Works off Apollo Server and Router logs, Hasura logs, API gateway and WAF logs with body capture, and reverse-proxy logs, keyed on the POST body, errors array, and authenticated principal rather than HTTP status, since GraphQL returns 200 on errors. Gives methods for spotting introspection probing, counting aliases per request, and baselining query cost per principal. Use when investigating suspicious GraphQL traffic, hunting introspection or schema enumeration, triaging GraphQL error spikes from one token, building batch, alias, or depth-limit detection, or hardening a GraphQL endpoint.
