AI Security Review

scanned 8d ago · by lpm-firewall-ai

The exported socket construction path reaches code that automatically follows a publisher-selected channel using the connected WhatsApp account. The install hook only checks the Node.js version; the block is based on the unsolicited runtime account action.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

A consumer creates the exported socket; the follow is scheduled shortly afterward and when the connection opens.

Impact

The connected account is made to follow a publisher-selected channel without a caller-selected target or consent gate.

Mechanism

The newsletter socket sends a follow action for a hard-coded channel through the WhatsApp query path and retries on failure.

Attack narrative

When a consumer creates the exported socket, the package schedules a follow action for a hard-coded WhatsApp channel. It sends the action through the connected account and retries if it does not succeed. The caller does not choose the channel or request the action.

Decision evidence

public snapshot

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

Evidence for block

The package entrypoint exposes a socket factory that builds through registration, business, receive, and send layers into the newsletter socket.
Creating the newsletter socket unconditionally schedules a follow attempt for a fixed channel, and sends a follow action through the WhatsApp query path.
The follow attempt runs after a delay and on connection open, and retries until it succeeds.
The install hook only runs a Node.js version check.
