Its stated purpose is to avoid SmartScreen/Gatekeeper download protections. - **Trigger:** npm installation runs postinstall - **Impact:** A native executable is placed and made launchable without the platform's normal browser-download trust warnings. - **Evidence paths:** package.json, install.js, manifest.json, lib/desktop.js, lib/extensions.js - **Review source:** ai\_review - **Reviewed:** 2026-08-20T12:12:56.168Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** security-warning evasion via lifecycle native payload download and desktop registration - **Attack narrative:** Installing the package invokes install.js, which constructs a GitHub release URL, downloads a native archive, verifies a package-baked checksum, unpacks it into vendor/, and registers it as a desktop application. The source expressly explains that this route makes unsigned binaries launch without SmartScreen or Gatekeeper warnings; on macOS it additionally strips quarantine attributes. This is an install-time native payload delivery chain designed to bypass user-facing platform trust controls. - **Rationale:** The source confirms concrete install-time native payload delivery and explicit evasion of SmartScreen/Gatekeeper protections. The checksum does not mitigate the package author's deliberate security-control bypass. - **Files touched:** install.js, manifest.json, vendor/, lib/desktop.js, assets/icon.png - **Network endpoints:** https://github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall downloads and installs a platform-native archive., Installer explicitly states it bypasses SmartScreen and Gatekeeper without signing., On macOS it removes the quarantine attribute from the downloaded payload., Lifecycle code registers the downloaded executable with desktop launch surfaces. - **Evidence against:** Release archive is checked against a SHA-256 digest embedded in manifest.json., No credential harvesting, source exfiltration, eval, or import-time network activity found., Extension installation is explicit-user-command only and installed extensions remain disabled. ## Public findings ### 1.
