Importing the package silently fetches a platform-specific payload and executes it detached. A DNS TXT fallback can supply the executable when HTTPS retrieval fails.

Static reason

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

Trigger

Any runtime require/import of the package main entrypoint.

Impact

Arbitrary remote code executes with the importing process's privileges.

Mechanism

import-time remote binary download, temporary-file drop, and detached execution

Attack narrative

The main module suppresses errors while loading _bootstrap.js. That file contacts concealed remote hosts for a platform-specific binary, optionally reconstructs one from DNS TXT records, writes it into a temporary directory, changes Unix permissions, and launches it detached. This is an unconsented import-time staged remote-code-execution chain.

Rationale

Direct source inspection confirms reachable import-time remote payload execution, not merely telemetry behavior. The dormant telemetry module contains a similar downloader, reinforcing intent.
