The source expressly frames this path as bypassing platform download-reputation protections. - **Trigger:** npm installation runs postinstall. - **Impact:** An unconsented install executes a downloaded unsigned native payload and creates per-user OS integration. - **Evidence paths:** package.json, install.js, manifest.json, lib/desktop.js, uninstall.js, bin/francois.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T03:33:36.974Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote native payload installation with security-control evasion and desktop persistence. - **Attack narrative:** On npm postinstall, install.js downloads a release archive from GitHub, verifies its package-supplied hash, extracts the native application, and on macOS recursively removes com.apple.quarantine. It then creates OS-visible application integration: Start Menu/registry entries on Windows, a ~/Applications bundle on macOS, or Linux desktop/icon entries. Comments explicitly state the installer exists to avoid SmartScreen and Gatekeeper behavior for unsigned builds. - **Rationale:** The lifecycle script installs an opaque native payload and intentionally evades platform trust controls without an explicit user command. Hash pinning limits transit tampering but does not mitigate the package-author-controlled payload or the bypass behavior. - **Files touched:** install.js, manifest.json, lib/platform.js, lib/desktop.js, vendor/, assets/icon.png - **Network endpoints:** https://github.com/antoine-gmnz/francois/releases/download/v0.17.12/ ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs install.js as postinstall., install.js downloads and extracts a native app during installation., install.js explicitly aims to bypass SmartScreen/Gatekeeper and removes macOS quarantine., lib/desktop.js persists the downloaded app in OS launch surfaces. - **Evidence against:** manifest.json pins per-platform SHA-256 hashes., No source evidence of credential harvesting or data exfiltration., Cleanup code removes the package-owned desktop integration. ## Public findings ### 1.
