WhatsApp Web API Library

AI Security Review

scanned 3h ago · by lpm-firewall-ai

Normal use silently changes the user's WhatsApp account by following and muting remotely chosen newsletters. The remote list lets the publisher change targets after installation.

Static reason

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

Trigger

A consumer creates a socket and its WhatsApp connection opens.

Impact

Unconsented account subscriptions and persistent changes to the user's WhatsApp newsletter state.

Mechanism

Remote-controlled automatic newsletter follow and mute actions.

Attack narrative

The exported socket construction reaches the newsletter socket. After a WhatsApp connection opens, the package waits 30 seconds, downloads a publisher-controlled list of newsletter IDs, then follows and mutes each valid ID through the authenticated session. This is not exposed as an opt-in feature or configuration option, and the remote list makes the target set changeable without a package update.

Rationale

The package contains a concrete, hidden runtime action that mutates a user's WhatsApp account using a remotely controlled target list. This warrants blocking despite the benign Node-version preinstall check.
