The installer deliberately suppresses platform download-security signals. - **Trigger:** npm install runs the postinstall hook. - **Impact:** A remote native payload is placed in the user environment with OS security warnings bypassed and persistent launch entries created. - **Evidence paths:** package.json, install.js, lib/desktop.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-09-01T09:26:29.329Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote native payload installation, quarantine removal, and desktop registration. - **Attack narrative:** On npm installation, the postinstall script builds a GitHub release URL from its embedded manifest, downloads and extracts a platform archive, and installs it into vendor. It explicitly states that this delivery route avoids SmartScreen and Gatekeeper for an unsigned binary, and it additionally removes macOS quarantine metadata. It then creates per-user desktop integration, including a macOS Applications bundle, Linux desktop entry, or Windows shortcuts and registry entries. The embedded checksum only authenticates the archive against a value controlled by the same published package. - **Rationale:** This is a lifecycle bootstrapper for a remote unsigned native payload that deliberately bypasses operating-system download protections and persists it in user launch surfaces. The behavior is concrete and automatic at install time. - **Files touched:** vendor/, ~/Applications/Francois.app, ~/.local/share/applications/francois.desktop, ~/.local/share/icons/hicolor/128x128/apps/francois.png, HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\francois - **Network endpoints:** https://github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall hook runs the installer., The installer explicitly describes bypassing SmartScreen and Gatekeeper for an unsigned binary., At install time it downloads and extracts a release archive, then removes macOS quarantine attributes., It registers the downloaded payload with per-user desktop launch surfaces. - **Evidence against:** The archive is checked against a SHA-256 value included in the package manifest., No source evidence shows credential collection or secret exfiltration. ## Public findings ### 1.
