droid@0.195.0
Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package contains a concrete install-time remote native-payload path without explicit payload integrity verification. Its actions are otherwise package-local and no malicious exfiltration, persistence outside the package, or AI-agent control-surface tampering is present.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall when the matching optional platform dependency is unavailable
Impact
A compromised or substituted registry/tarball response could supply code that runs later through the droid command.
Mechanism
registry-mediated native binary download, extraction, and local executable write
AI rationale
The package contains a concrete install-time remote native-payload path without explicit payload integrity verification. Its actions are otherwise package-local and no malicious exfiltration, persistence outside the package, or AI-agent control-surface tampering is present.

Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- postinstall invokes install.js.
- When its optional platform dependency is absent, the installer fetches a registry-selected tarball, extracts a native binary, and writes it executable.
- The fallback does not verify a tarball digest or signature before installing the binary.
Evidence against
- The lifecycle script only changes this package's bin/droid shim or its local bin directory.
- Network bootstrap is limited to the npm registry/tarball URL supplied by its packument.
- NPM_TOKEN is attached only when the current request host includes npmjs.org; no general credential harvesting or exfiltration was found.
- No source writes shell profiles, AI-agent configuration, or other foreign control surfaces.

Install Time Lifecycle Scripts
Package defines install-time lifecycle scripts.
package.jsonView on unpkg9scripts.postinstall = node install.js
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.
