It then installs desktop-launcher integration for that payload. - **Trigger:** npm postinstall - **Impact:** An unreviewed remote native application can run with the installing user's permissions. - **Evidence paths:** package.json, install.js, lib/desktop.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-08-26T17:39:40.037Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Downloads, unpacks, de-quarantines, and registers an unsigned native payload. - **Attack narrative:** During installation, the package fetches a release archive from GitHub, verifies it only against a checksum bundled in the package, extracts it, and installs it as a desktop application. Its source states that this delivery route is intended to avoid SmartScreen and Gatekeeper checks for an unsigned build. On macOS it also removes the quarantine attribute. This is a concrete attempt to bypass operating-system trust protections while installing a remote native payload. - **Rationale:** The package performs install-time delivery and registration of an unsigned native payload while explicitly evading platform security checks. The bundled checksum does not address the intentional trust-control bypass. - **Files touched:** install.js, manifest.json, vendor/, lib/desktop.js, ~/Applications/Francois.app, ~/.local/share/applications/francois.desktop - **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 postinstall hook downloads and unpacks a platform binary., The installer explicitly bypasses SmartScreen and Gatekeeper protections for an unsigned build., On macOS it removes the quarantine attribute from the downloaded payload., The lifecycle installer registers the downloaded app in user desktop locations. - **Evidence against:** The downloaded archive is checked against a SHA-256 value in the bundled manifest., Plugin installation requires an explicit command and leaves plugins disabled. ## Public findings ### 1.
