On macOS it also removes quarantine metadata. - **Trigger:** npm install - **Impact:** Executes an externally hosted unsigned binary and creates per-user desktop integration. - **Evidence paths:** package.json, install.js, manifest.json, lib/desktop.js - **Review source:** ai\_review - **Reviewed:** 2026-08-25T20:54:29.009Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote native payload install with SmartScreen/Gatekeeper evasion - **Attack narrative:** Installing the package runs a postinstall hook that downloads a platform-native archive from GitHub, extracts it, and registers it with the operating system. The source expressly frames npm delivery as a way to avoid SmartScreen and Gatekeeper and additionally strips macOS quarantine metadata. Although it validates the archive against a bundled SHA-256 value, that does not mitigate the intentional security-control bypass or establish trust in the fetched native payload. - **Rationale:** The source implements an install-time remote native payload chain explicitly designed to evade OS download protections, followed by persistence-like desktop registration. This is concrete malicious install behavior, not merely a normal downloader. - **Files touched:** install.js, manifest.json, lib/platform.js, lib/desktop.js, vendor/, ~/Applications, ~/.local/share/applications, HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall - **Network endpoints:** https://github.com/antoine-gmnz/francois/releases/download/v0.35.1/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Postinstall downloads and installs a native release payload., Source explicitly says npm download is used to bypass SmartScreen and Gatekeeper., It removes macOS quarantine attributes from the installed payload., Install persists desktop/OS integration per user. - **Evidence against:** Archive SHA-256 is checked against the bundled manifest., No credential harvesting or source-level exfiltration found., Extension installation is explicit and remains disabled by default. ## Public findings ### 1.
