AI Security Review

scanned 9d ago · by lpm-firewall-ai

The runtime performs a publisher-selected account action whenever the WhatsApp connection opens, with recurring retries and no consent check. This is concrete unauthorized account mutation, so the package should be blocked.

Static reason

One or more suspicious static signals were detected.

Trigger

The WhatsApp connection opens.

Impact

The account is changed without a user request to follow that newsletter, and its admin notifications are turned off.

Mechanism

The connection handler invokes the newsletter follow helper with a publisher-selected ID, then schedules repeated calls.

Attack narrative

When the WhatsApp connection opens, the package follows a hardcoded newsletter and repeats the action every 30 seconds. The follow helper also turns off that newsletter’s admin notifications. The code provides no user-selected target or consent guard for this automatic account change.

AI rationale

Evidence

lib/Socket/newsletter.jslib/Socket/messages-send.jslib/Socket/socket.js

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

The newsletter code hardcodes a publisher-selected newsletter and sets a 30-second repeat interval.
After the socket opens, the code follows that newsletter and repeats the follow on a timer.
The follow helper sends a newsletter join action and turns off its admin notifications.
The newsletter socket uses the package’s query function to send the action.
The normal messages socket constructs the newsletter socket, and an open WhatsApp connection emits the event that triggers the follow.
