→Detect XXE exploitation attempts against WSO2 API Manager Management Console by matching HTTP interactions triggered via out-of-band (OOB) DNS/HTTP callbacks (interactsh_protocol: http)
→Confirm exploitation by checking the response body for the WSO2-specific error string 'Failed to install the generic artifact type', indicating the XXE payload was processed by the Management Console

·Both matcher conditions must be satisfied simultaneously (matchers-condition: and) — an OOB HTTP callback AND the specific body string must both be present to confirm exploitation, reducing false positives
·Affected versions are WSO2 API Manager through 3.1.0 and API Microgateway 2.2.0; the XXE attack surface is the Management Console component ↗
