Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is a package-aligned native CLI installer with a registry fallback, not a demonstrated malicious chain. Its automatic binary setup is limited to its own launcher and the inspected code contains no concrete exfiltration, persistence, or broad project mutation.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation when the matching optional platform dependency is unavailable.
Impact
A package-local CLI binary is written and linked; no source evidence shows credential theft, foreign-file mutation, or persistence.
Mechanism
Registry fallback for a package-local platform executable.
AI rationale
This is a package-aligned native CLI installer with a registry fallback, not a demonstrated malicious chain. Its automatic binary setup is limited to its own launcher and the inspected code contains no concrete exfiltration, persistence, or broad project mutation.

Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The package runs install.js automatically after installation.
- If its optional platform package is absent, the installer fetches a same-version platform archive from the npm registry and writes its binary locally.
- On Unix, the installer replaces only its own droid launcher with a link to that platform binary.
Evidence against
- The download selects a package from a fixed internal platform mapping and uses the package's own version.
- The only token use is an npm authorization header restricted to npmjs.org; no collection or exfiltration is present.
- Source writes and links files only beneath this package's bin directory, with no foreign configuration or shell-profile mutation.
- No self-dependency, evaluator, obfuscated payload, destructive action, or AI-agent control-surface write was found.

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