## Security analysis

### Published attack-surface review

- **Summary:** Installation automatically executes a shell pipeline. It exfiltrates the local account name to an external endpoint.

- **Trigger:** npm install (postinstall lifecycle)

- **Impact:** Discloses the installing user's local account identity to a third party.

- **Evidence paths:** package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-13T22:03:01.648Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** pipes whoami output into curl POST

- **Attack narrative:** On installation, npm runs the package's postinstall command. The command obtains the current local username with whoami and pipes it to curl, which POSTs the value to a remotely hosted ngrok endpoint without user interaction.

- **Rationale:** The only package file defines an automatic install-time identity-exfiltration command. This is concrete unauthorized data exfiltration.

- **Files touched:** package.json

- **Network endpoints:** 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 a postinstall lifecycle hook., The hook sends the installing user's whoami output to an external ngrok URL.
