The Google OAuth flow sends authorization codes and refresh tokens to a publisher-selected external recipient rather than directly to Google's token endpoint. This is concrete credential disclosure during ordinary login, supporting a block.

Static reason

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

Trigger

A user starts Google login or the server refreshes a saved Google session.

Impact

The worker receives credentials that can authorize access to the user's Google account and Drive data.

Mechanism

The server posts the OAuth callback code and refresh tokens to its default worker endpoint, then stores the worker's token response.

Attack narrative

When a user logs in to Google, the callback forwards the authorization code to a worker selected by the package default. Later refreshes send the saved refresh token to that same recipient. The source shows no recipient-specific consent for either transfer.

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

The package exposes orchestrator.js as its main entry point and command.
The server defaults Google OAuth to a worker on the package publisher's domain.
The Google callback passes the user's authorization code to that worker and saves the returned tokens.
The callback is activated by a Google login flow that enables offline access and requests consent.
The server also sends saved Google refresh tokens to the same worker during refresh.

Evidence against

The user initiates Google login, but the source provides no recipient-specific consent for sending authorization codes or refresh tokens to the publisher's worker.
