AI Security Review

scanned 4d ago · by lpm-firewall-ai

The package performs an unrequested, publisher-selected account action after login, which is concrete attack behavior. The preinstall script is only a Node version check and does not change this runtime finding.

Static reason

One or more suspicious static signals were detected.

Trigger

A successful WhatsApp login opens the connection.

Impact

The user's account is changed by subscribing to a publisher-selected newsletter.

Mechanism

The socket checks subscription status and sends a follow query for the package-selected newsletter without a user consent check.

Attack narrative

After login succeeds, the socket calls an automatic subscription routine. That routine targets a hard-coded newsletter and issues a follow query if the account is not already subscribed. The inspected path shows no user consent guard for this account action.

AI rationale

Evidence

lib/Socket/socket.js

Network endpoints1

Decision evidence

public snapshot

AI called this Malicious at 97.0% confidence as Malware with low false-positive risk.

Evidence for block

After successful login, the socket automatically starts a default-newsletter subscription check.
The target newsletter ID is hard-coded, and the code subscribes the account when it is not already subscribed.
The subscription is sent through a WhatsApp query; no user consent check guards this account action.

Evidence against

The preinstall hook only checks the Node.js major version and exits on versions below 20.
The inspected subscription path does not establish credential exfiltration or remote code execution.
