Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe flagged primitives implement a conventional platform-specific CLI binary installer. Source inspection found no concrete malicious chain, foreign control-surface mutation, credential exfiltration, or destructive behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall; the droid command at user invocation.
Impact
Installs or links the CLI's own native executable; no confirmed persistence outside the package or data exfiltration.
Mechanism
platform binary resolution, fallback download, and package-local shim linking.
AI rationale
The flagged primitives implement a conventional platform-specific CLI binary installer. Source inspection found no concrete malicious chain, foreign control-surface mutation, credential exfiltration, or destructive behavior.

Decision evidence
public snapshotAI called this Clean at 93.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json runs postinstall via install.js.
- install.js can fetch a version-pinned platform package from registry.npmjs.org if optional dependencies are absent.
- install.js writes the extracted platform binary and replaces only its own bin/droid shim.
Evidence against
- Network access is limited to npm registry metadata/tarball retrieval for the package's own platform binary.
- NPM_TOKEN is sent only when the destination hostname includes npmjs.org; no other secret collection or exfiltration is present.
- Lifecycle mutations are confined to package-local bin/droid and a temporary backup.
- platform.js uses system commands only for CPU AVX2 detection.
- bin/droid executes the resolved package-owned platform binary from an explicit platform-package mapping.
- No AI-agent configuration, shell profile, credential-store, or foreign-project writes occur; PATH guidance is printed only.

Install Time Lifecycle Scripts

Install-time code downloads an unverified remote native executable, stages it locally, activates an executable path, and exposes it to process execution.

Unverified Remote Native Payload Install
Install-time source downloads a native archive from a fixed external host without transport verification, extracts it, and installs an executable payload.
