The shipped JavaScript cannot establish the downloaded binary's behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-01T11:57:21.365Z - **Finished:** 2026-08-01T11:57:45.521Z - **Download time:** 260 ms - **Static scan time:** 91 ms - **AI review time:** 23804 ms - **Total time:** 24156 ms ## Security analysis ### Published attack-surface review - **Summary:** Postinstall downloads a checksum-pinned native payload, extracts it, and makes it launchable through per-user desktop integration. The shipped JavaScript cannot establish the downloaded binary's behavior. - **Trigger:** npm installation; later user launch of francois. - **Impact:** A release-hosted binary is placed on disk and registered as a desktop application during installation. - **Evidence paths:** package.json, install.js, manifest.json, lib/desktop.js, bin/francois.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-01T11:57:45.521Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote native payload staging with desktop registration - **Rationale:** This is a disclosed, checksum-verified remote-binary installer rather than confirmed malware, but it stages an uninspectable native payload during postinstall and deliberately bypasses macOS quarantine. That warrants a warning, not a publish block. - **Files touched:** install.js, manifest.json, lib/platform.js, lib/desktop.js, vendor/, ~/Applications, ~/.local/share/applications/francois.desktop, ~/.local/share/icons/hicolor/128x128/apps/francois.png - **Network endpoints:** https://github.com/antoine-gmnz/francois/releases/download/v0.17.4/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall install.js., install.js downloads a platform archive from GitHub releases during install., install.js extracts the remote archive into vendor/ and registers its executable with the OS., install.js removes macOS com.apple.quarantine from the downloaded payload., lib/desktop.js creates per-user desktop launchers and a Windows HKCU uninstall entry. - **Evidence against:** manifest.json pins release asset names and SHA-256 digests., install.js verifies the archive digest before extraction., No source evidence of credential harvesting, data exfiltration, or AI-agent configuration writes., The network download and desktop integration are disclosed in README.md. ## Public findings ### 1.
