Factory Droid CLI - AI-powered software engineering agent
AI Security Review
scanned 22d ago · by lpm-firewall-aiThe installer has a conditional credential exposure risk: it uses a substring hostname check and follows redirects while forwarding NPM_TOKEN. The matching scoped binary packages and lack of source evidence for an unrelated destination keep this at suspicious rather than malicious.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation when the platform binary is unavailable and the fallback downloads it.
Impact
A lookalike destination could receive the npm token under those conditions; an actual unrelated destination is not established by the inspected source.
Mechanism
The installer obtains a tarball URL from registry metadata, follows redirects, and attaches NPM_TOKEN to requests whose hostname contains the substring “npmjs.org”.
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall fallback fetches a tarball URL supplied by npm registry metadata and passes it to the request helper.
- The request helper attaches NPM_TOKEN when the hostname contains “npmjs.org” and follows redirects recursively, so a lookalike hostname can receive the token if the fallback is triggered.
- The fallback runs when the platform binary is unavailable; source does not establish that this release sends the token to an unrelated host.
Evidence against
- The manifest pins platform binaries to matching 0.241.0 releases under the @factory scope.
- The installer writes the extracted binary into its own bin directory and links it to the package’s droid shim.

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