droid@0.227.0
Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe postinstall behavior is package-local binary setup and the network fallback is for declared platform binaries. Static inspection found no concrete malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
npm postinstall or an explicit droid command invocation.
Impact
No confirmed credential theft, external control-surface mutation, persistence, or destructive action was found.
Mechanism
The installer selects a platform dependency, optionally downloads its npm tarball, and links the local bin/droid shim to that binary.
AI rationale
The postinstall behavior is package-local binary setup and the network fallback is for declared platform binaries. Static inspection found no concrete malicious behavior.
Evidence
bin/droid

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json invokes install.js only as a postinstall hook.
- The installer obtains a platform binary from declared optional dependencies or the npm registry and links it only into this package's bin path.
- The installer attaches NPM_TOKEN only when the parsed request hostname contains npmjs.org.
- The command shim passes user arguments to the selected platform binary.

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