francois@0.17.4

Mission control for your Claude Code fleet — installs the Francois desktop app without an installer.

AI Security Review

scanned 14d ago · by lpm-firewall-ai

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.

Static reason

One or more suspicious static signals were detected.

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.

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.

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

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.
