The payload is launched later by the user-facing CLI. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 96.0% - **Started:** 2026-08-14T14:37:23.624Z - **Finished:** 2026-08-14T14:38:17.067Z - **Download time:** 255 ms - **Static scan time:** 202 ms - **AI review time:** 52985 ms - **Total time:** 53443 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall retrieves an unsigned native archive, bypasses platform warning controls, and installs desktop integration. The payload is launched later by the user-facing CLI. - **Trigger:** npm install executes postinstall; later \`francois\` launches the extracted executable. - **Impact:** A remote native binary is installed outside normal browser-originated platform warnings and registered for desktop launch. - **Evidence paths:** package.json, install.js, lib/desktop.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-08-14T14:38:17.067Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle-fetched native payload with explicit OS security-warning bypass. - **Rationale:** This is a concrete lifecycle-installed native payload designed to evade platform reputation and quarantine warnings. It warrants a warning, rather than a block, because the inspected code does not mutate a foreign/broad AI-agent control surface or show theft/exfiltration. - **Files touched:** manifest.json, vendor/, ~/Applications/Francois.app, ~/.local/share/applications/francois.desktop - **Network endpoints:** https://github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall runs a downloader that explicitly bypasses SmartScreen/Gatekeeper protections for an unsigned binary., Install lifecycle downloads a remote platform archive, verifies a package-supplied hash, extracts it, and registers the payload with the OS., macOS postinstall recursively removes the quarantine attribute from the downloaded payload. - **Evidence against:** Default download host is fixed to GitHub and the archive hash is pinned in manifest.json., No source evidence of credential collection, file harvesting, or outbound exfiltration., The downloaded binary is not executed until a later user CLI launch. ## Public findings ### 1.
