The payload is persisted and registered with OS launch surfaces. - **Trigger:** npm install runs the postinstall hook. - **Impact:** Executes a remotely hosted native application after installation and makes it discoverable through desktop integration. - **Evidence paths:** package.json, install.js, manifest.json, lib/desktop.js, lib/platform.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T21:40:51.443Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** download, checksum-verify, unpack, de-quarantine, and register native payload - **Attack narrative:** On npm postinstall, the package fetches a platform-native archive from GitHub, verifies only a package-bundled digest, extracts it, and on macOS removes quarantine metadata. It then registers the resulting app in user desktop/OS integration surfaces. Its own source states that the npm path is intended to avoid SmartScreen and Gatekeeper checks for unsigned builds. - **Rationale:** The automatic native-payload install is explicitly designed to bypass host download-security controls, then persists the payload through OS integration. Digest checking does not mitigate the package author’s intentional delivery of that unsigned payload. - **Files touched:** install.js, manifest.json, lib/platform.js, lib/desktop.js, vendor/, ~/Applications, ~/.local/share/applications, ~/.local/share/icons, HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall, HKCU\\Software\\Classes\\AppUserModelId - **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:** package.json runs install.js automatically via postinstall., install.js downloads a platform-native archive during install and extracts it to vendor/., install.js explicitly states its purpose is to bypass SmartScreen/Gatekeeper quarantine behavior for unsigned binaries., install.js removes macOS com.apple.quarantine recursively from the installed payload., lib/desktop.js registers the downloaded app in per-user OS launch surfaces. - **Evidence against:** manifest.json pins GitHub release asset names and SHA-256 digests., install.js verifies each downloaded archive against the bundled SHA-256 before extraction., No credential harvesting or package-source exfiltration was found. ## Public findings ### 1.
