The installer’s stated purpose is to avoid browser-origin security markings for unsigned binaries. - **Trigger:** npm install, including transitive lifecycle execution - **Impact:** Unconsented installation and persistence of an externally hosted unsigned executable, then execution through the CLI. - **Evidence paths:** package.json, install.js, manifest.json, lib/desktop.js, lib/platform.js, bin/francois.js - **Review source:** ai\_review - **Reviewed:** 2026-08-11T21:05:44.661Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote native-payload download, extraction, and OS desktop registration - **Attack narrative:** During postinstall, the package constructs a GitHub release URL from its bundled manifest, downloads a platform-native archive, checks a hash supplied by that same package, extracts it, and registers the payload with OS launch surfaces. Its comments expressly frame npm delivery as a way for unsigned binaries to avoid SmartScreen and Gatekeeper browser-origin protections. The installed payload is subsequently launched by the package CLI. - **Rationale:** This is a concrete install-time remote native-payload chain with explicit security-control evasion and per-user OS integration. A bundled hash check does not independently establish trust in the remote executable. - **Files touched:** install.js, lib/desktop.js, lib/platform.js, vendor/, ~/Applications, ~/.local/share/applications, ~/.local/share/icons, HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall - **Network endpoints:** https://github.com/antoine-gmnz/francois/releases/download/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall downloads, extracts, and installs a platform-native binary., Installer explicitly seeks to bypass SmartScreen/Gatekeeper quarantine protections., Install lifecycle creates per-user OS launch integration for the downloaded payload. - **Evidence against:** Archive SHA-256 is checked against the bundled manifest before extraction., No source evidence of credential harvesting or network exfiltration. ## Public findings ### 1.
