AI Security Review

scanned 9d ago · by lpm-firewall-ai

The exported socket path reaches a default-on connection handler that follows publisher-selected newsletters on the authenticated account. The opt-out does not provide affirmative consent to these account changes.

Static reason

One or more suspicious static signals were detected.

Trigger

The WhatsApp connection opens while autoFollowNewsletters is not explicitly false.

Impact

The account is changed without the user selecting those newsletters.

Mechanism

A connection event schedules FOLLOW requests for each hard-coded newsletter ID.

Attack narrative

When the connection opens, the library schedules FOLLOW requests for eight hard-coded newsletter IDs. This changes the connected account’s subscriptions without the user selecting those newsletters; the behavior is disabled only by explicitly setting autoFollowNewsletters to false.

AI rationale

Evidence

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

Decision evidence

public snapshot

AI called this Malicious at 96.0% confidence as Malware with low false-positive risk.

Evidence for block

The newsletter socket contains eight publisher-selected newsletter IDs and enables automatic following unless explicitly disabled.
When the connection opens, it schedules a FOLLOW request for each selected newsletter.
The exported makeWASocket builds the package socket, and makeMessagesSocket composes the newsletter socket.

Evidence against

The automatic behavior has an explicit opt-out: setting autoFollowNewsletters to false disables it.
