AI Security Review

scanned 10d ago · by lpm-firewall-ai

Importing the package automatically retrieves a platform-specific remote binary, stores it in a temporary directory, and executes it detached. The payload source may be switched through DNS TXT records.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Any runtime require/import of index.js, including the README's documented require call.

Impact

Arbitrary code execution as the consuming application's user.

Mechanism

import-time remote binary download, drop, chmod, and detached execution

Attack narrative

Requiring index.js silently imports _helpers.js. Its top-level run() downloads a binary selected by OS/architecture from obfuscated Workers hosts, falling back to base64 DNS TXT data from .ru domains. It writes the bytes to a temporary executable path and launches it detached with /bin/sh or cmd.exe; no hash, signature, or user opt-in is present.

Rationale

This is a concrete import-time remote payload execution chain unrelated to the advertised React type/component package. The lack of install hooks does not mitigate execution on ordinary package use.
