## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious payload is present in the inspected snapshot. The install hook can retrieve an unverified platform archive from a remote endpoint.

- **Trigger:** npm automatically runs postinstall during package installation.

- **Impact:** A compromised endpoint or network path could supply a staged native payload; no confirmed attack behavior was available for inspection.

- **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-22T10:36:37.778Z

### AI review details

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

- **Mechanism:** The bootstrap disables TLS certificate verification, follows redirects, downloads an archive, and extracts it into node\_modules.

- **Rationale:** The automatic, unauthenticated remote binary staging path is a concrete supply-chain risk, but the inspected source does not prove malicious payload behavior or exfiltration.

- **Files touched:** .platform-bootstrap-work, node\_modules, bin/.onecode

- **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The package automatically runs a postinstall script., Postinstall invokes the platform bootstrap routine., The bootstrap downloads a platform archive from a raw-IP HTTPS endpoint while disabling certificate verification and follows redirects., The downloaded archive is extracted and installed without an integrity check.

- **Evidence against:** The inspected JavaScript contains no credential harvesting, exfiltration, or destructive actions., The downloaded binary is launched only when the user invokes the onecode command; its contents are not available in this snapshot.
