This is an unconsented credential-exfiltration chain. - **Rationale:** Direct source inspection confirms an install-time cloud-credential harvesting and exfiltration command. There is no benign package functionality to offset this behavior. - **Files touched:** package.json - **Network endpoints:** http://169.254.170.2/v2/credentials/, https://mourner-slot-explicit.ngrok-free.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json defines an automatic postinstall hook., The hook fetches from a link-local cloud credentials endpoint., It pipes the fetched response to an external ngrok host via curl POST. - **Evidence against:** No other package files or legitimate runtime functionality are present. ## Public findings ### 1.
