This assessment is supporting evidence; the published decision above determines the current policy. No attack was identified. The postinstall downloads the package’s versioned desktop app and verifies its archive checksum before extraction. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-07T20:53:08.363Z - **Finished:** 2026-10-07T20:54:10.502Z - **Download time:** 516 ms - **Static scan time:** 207 ms - **AI review time:** 61415 ms - **Total time:** 62139 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified. The postinstall downloads the package’s versioned desktop app and verifies its archive checksum before extraction. - **Trigger:** npm install runs the postinstall hook; normal app execution requires invoking the francois command. - **Impact:** The intended effect is installing and launching the Francois desktop app; the inspected source did not establish malicious behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T20:54:10.502Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer downloads a release archive, validates its SHA-256 against the shipped manifest, extracts it, and registers per-user desktop integration. - **Rationale:** The install-time download and quarantine handling are explicitly used to install the package’s own desktop application. The fixed versioned release and shipped checksum provide source evidence of package-aligned behavior, with no concrete attack established. - **Files touched:** package.json, install.js, manifest.json, bin/francois.js, lib/desktop.js, lib/extensions.js - **Network endpoints:** https://github.com/antoine-gmnz/francois ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Final policy explanation:** The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. - **Evidence for AI clean decision:** The postinstall hook fetches the Francois release archive and checks it against the SHA-256 value shipped in the package manifest., The shipped manifest selects a versioned release from the package’s own GitHub repository., The launcher starts the installed app when invoked; extension files are stored in the app’s own user directory. - **Evidence against:** The installer permits an environment override of the download base and removes macOS quarantine attributes from the installed payload. ## Affected versions and remediation This report applies to francois@0.34.4. - Review the evidence and your use of francois@0.34.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
