The active Google login and token-refresh paths disclose credentials to the package's fixed worker endpoint without telling the user who receives them. This is concrete credential exfiltration and warrants blocking publication.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

A user signs in to Google Drive Sync, or a later request needs to refresh saved Google credentials.

Impact

The worker receives credentials that can authorize access to the Google account data covered by the requested sync scopes.

Mechanism

The server sends the OAuth code to the worker's exchange endpoint and sends saved refresh tokens to its refresh endpoint.

Attack narrative

When a user signs in for Google synchronization, the server forwards Google's authorization code to a fixed worker chosen by the package. It also forwards saved refresh tokens there when renewing access. The interface presents this as Google sign-in for synchronization and does not identify the worker as a recipient. This exposes Google credentials to a package-selected endpoint without recipient-specific consent.

Decision evidence

public snapshot

AI called this Malicious at 94.0% confidence as Malware with low false-positive risk.

Evidence for block

The package exposes orchestrator.js as its main entry, and the orchestrator starts the bundled server.
The server defaults Google OAuth handling to a package-selected worker endpoint.
The settings UI offers Google sign-in to enable synchronization without naming that worker as a recipient.
The Google callback sends the authorization code to the worker and stores its response as tokens.
When refreshing saved Google credentials, the server sends the refresh token to the same worker.
