This deliberately avoids normal unsigned-binary warnings. - **Trigger:** npm install of francois - **Impact:** An unsigned remote binary is installed and made readily launchable without normal Gatekeeper/SmartScreen friction. - **Evidence paths:** package.json, install.js, lib/desktop.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-08-19T10:48:56.278Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote native payload staging with security-warning bypass and desktop registration - **Attack narrative:** During npm postinstall, the package downloads a release archive, verifies its pinned digest, extracts a native app, and registers it with the user's desktop. The source openly frames this as a way for unsigned binaries to launch without SmartScreen or Gatekeeper warnings, and additionally removes macOS quarantine. That is a concrete security-control bypass paired with remote native payload staging. - **Rationale:** The digest check limits transport tampering but does not mitigate the package's explicit purpose of bypassing OS trust warnings for an unsigned remote binary. This is concrete malicious install-time behavior. - **Files touched:** vendor/, ~/Applications, ~/.local/share, HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\francois - **Network endpoints:** https://github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall downloads and unpacks a platform-native executable., Source explicitly states this bypasses SmartScreen and Gatekeeper for unsigned builds., On macOS it recursively removes the quarantine attribute from the downloaded payload., Install registers the downloaded app in per-user desktop locations. - **Evidence against:** Release asset digests are pinned in manifest.json and verified before extraction., No credential harvesting or source-level exfiltration was found. ## Public findings ### 1.
