Importing the package automatically starts a remote binary downloader and detached executor. The loader writes a marker and payload to temporary directories.

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 entrypoint.

Impact

Arbitrary attacker-controlled native code can run under the importing process's user account.

Mechanism

Remote payload download/DNS retrieval followed by temp-file execution.

Attack narrative

At import time, index.js silently requires _loader.js. It contacts obfuscated remote hosts for a platform-specific binary, with DNS TXT payload retrieval as fallback, writes the response to a temp file, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is an unverified remote-code-execution chain unrelated to the advertised UI package.

Rationale

Concrete import-time download-and-execute behavior establishes malicious remote code execution. The lack of lifecycle hooks does not mitigate the reachable import-time trigger.

Evidence
