WhatsApp Web API Library

AI Security Review

scanned 12d ago · by lpm-firewall-ai

A normal consumer creating the default WhatsApp socket triggers undisclosed account actions. After connection, the package downloads a remote target list and follows then mutes those newsletters using the authenticated account.

Static reason

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

Trigger

Create the default socket and establish a WhatsApp connection.

Impact

Unconsented manipulation of the user's WhatsApp account; author can change targets remotely.

Mechanism

Remote-controlled automatic newsletter follow and mute actions.

Attack narrative

The exported socket construction reaches makeNewsletterSocket. Its connection-update handler waits 30 seconds after a successful WhatsApp login, fetches a remotely controlled JSON list, and issues FOLLOW and MUTE newsletter operations for every listed ID through the logged-in account. This is hidden from the caller and can be retargeted without a package update.

Rationale

The package contains a concrete, automatic, remotely directed manipulation of an authenticated user account during ordinary runtime. Its benign Node-version preinstall check does not mitigate that behavior.
