## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall retrieves a platform-native payload, extracts it, and registers it as a desktop application. It deliberately removes macOS quarantine from the downloaded payload.

- **Trigger:** npm installation

- **Impact:** Executes and persists an unsigned remote application outside the package directory.

- **Evidence paths:** package.json, install.js, manifest.json, lib/desktop.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-17T22:11:19.550Z

### AI review details

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

- **Mechanism:** remote native payload download, extraction, quarantine removal, and desktop registration

- **Attack narrative:** On npm install, the package builds a GitHub release URL from its bundled manifest, downloads a native archive, verifies an author-controlled hash, extracts it to vendor/, and registers the resulting app with the OS. On macOS it recursively removes the quarantine attribute from the payload, explicitly facilitating launch of an unsigned app outside normal browser download protections.

- **Rationale:** This is concrete install-time delivery and persistence of a native executable with explicit security-control bypass behavior. The bundled checksum provides integrity only relative to the package author and does not mitigate that behavior.

- **Files touched:** install.js, manifest.json, lib/desktop.js, vendor/

- **Network endpoints:** https://github.com

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** postinstall automatically downloads and extracts a native executable., Install code explicitly bypasses macOS quarantine and promotes unsigned app launch., Lifecycle install registers persistent per-user desktop integration.

- **Evidence against:** Archive SHA-256 is checked against a value shipped in manifest.json before extraction.
