WhatsApp Web API Library

AI Security Review

scanned 2d ago · by lpm-firewall-ai

Creating and connecting the default WhatsApp socket automatically fetches remote newsletter IDs, then follows and mutes them on the user's account. The action is maintainer-controlled and unconsented.

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

User calls the default makeWASocket API and the WhatsApp connection opens.

Impact

Unauthorized modification of the connected WhatsApp account's newsletter subscriptions.

Mechanism

Remote-configured automatic WhatsApp newsletter follow and mute.

Attack narrative

At runtime, the default socket layer includes the newsletter socket. Once a WhatsApp session opens, it waits 30 seconds, downloads newsletter identifiers from the maintainer's GitHub URL, then follows and mutes every valid identifier through WhatsApp queries. The remote list lets the publisher change the accounts affected without a package update or caller opt-in.

Rationale

Source establishes a remote-controlled, automatic account-action chain that follows and mutes newsletters for a connected user. The install hook is benign, but does not mitigate this runtime behavior.
