Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is a transparent same-vendor platform-binary installer with package-local writes, not a self-dependency or broad consumer-system mutation. Its unverified fallback download is a supply-chain hardening concern, but static source inspection found no concrete malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package with lifecycle scripts enabled when its optional platform binary is unavailable.
Impact
A registry or redirect compromise could substitute the fallback executable, but the source shows no independent malicious behavior.
Mechanism
Downloads a same-version platform binary fallback and links the package command shim.
AI rationale
This is a transparent same-vendor platform-binary installer with package-local writes, not a self-dependency or broad consumer-system mutation. Its unverified fallback download is a supply-chain hardening concern, but static source inspection found no concrete malicious behavior.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- The automatic postinstall fallback downloads and writes a platform executable without a checksum.
- The fallback follows registry-provided tarball URLs and HTTP redirects.
Evidence against
- The lifecycle hook only selects a same-vendor, exact-version platform package listed as an optional dependency.
- Writes are limited to this package's bin directory, where the command shim is replaced or linked to the selected binary.
- The token is only attached when the request hostname contains npmjs.org; no file harvesting, secret exfiltration, or external configuration mutation is present.

Install Time Lifecycle Scripts
Package defines 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.
