Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource shows a package-aligned binary bootstrapper, not concrete malicious intent. Its unverified install-time native download and execution warrants a warning.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall when the platform optional dependency is unavailable
Impact
A compromised or redirected registry tarball could execute native code during installation.
Mechanism
registry-fetched native binary installation and execution
AI rationale
Source shows a package-aligned binary bootstrapper, not concrete malicious intent. Its unverified install-time native download and execution warrants a warning.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Postinstall can fetch a platform binary from the npm registry when optional dependencies are absent.
- The fetched archive is extracted into bin/ without an integrity check, then the binary is executed for version validation.
Evidence against
- The only fixed network endpoint is npm's registry and the requested package/version comes from the package-owned platform mapping.
- Writes are limited to this package's bin shim/binary; no credential harvesting, agent-config mutation, or destructive behavior was found.

Install Time Lifecycle Scripts
Package defines install-time lifecycle scripts.
