The flagged signals are generic occurrences of the literal string 'POST' across the minified dist/index.js (lines 245-247, 679, 16066) without corroborating evidence of a hardcoded attacker C2 endpoint, install-time exfiltration, or credential harvest. No install/postinstall lifecycle hooks were identified that would auto-execute network behavior on `npm install`. Keyword co-occurrence in a minified rollup bundle is the weakest evidence shape and is consistent with normal HTTP client code in a CLI scaffolder. Routing for human review to confirm the destinations of those POST calls are documented Mastra endpoints rather than attacker infrastructure.\n\n## Source: ghsa-malware (12df16ee90f6c59f31e4b0b71f2dbf3a0b046e17ecae5e13399b69fec9f3c563)\nAny computer that has this package installed or running should be considered fully compromised.
