AI Security Review
scanned 2h ago · by lpm-firewall-aiThe default socket construction schedules a follow of a hard-coded WhatsApp newsletter through the user's session, without consent. This is an unrequested account action toward a publisher-selected target and meets the malicious account-action rule.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Calling makeWASocket(config) constructs the default socket; the follow is scheduled for 10 seconds later.
Impact
The user's authenticated WhatsApp account may be made to follow the selected newsletter without their request.
Mechanism
makeNewsletterSocket decodes a hard-coded newsletter ID and sends it with the FOLLOW query, without a user request or consent check.
Attack narrative
When an application creates the package's default WhatsApp socket, the constructor chain reaches makeNewsletterSocket. It schedules a FOLLOW request for a hard-coded newsletter ID after 10 seconds and sends it through the WhatsApp query path. This uses the user's account for an action toward a target selected by the package publisher, without an explicit request.
AI rationale
The default socket construction schedules a follow of a hard-coded WhatsApp newsletter through the user's session, without consent. This is an unrequested account action toward a publisher-selected target and meets the malicious account-action rule.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package entry point exports makeWASocket, whose default socket construction builds the communities and business layers.
- That default construction reaches makeMessagesSocket, which creates makeUsernameSocket; makeUsernameSocket creates makeNewsletterSocket.
- makeNewsletterSocket schedules an unconditional FOLLOW request after 10 seconds for a hard-coded, base64-encoded newsletter ID.
- The follow is sent through the WhatsApp w:mex query path using the socket query.
- The preinstall script only rejects Node versions below 20; it does not explain or gate the automatic follow.
Evidence against
- The package describes itself as a WebSocket library for interacting with WhatsApp, and newsletter-follow functionality fits that purpose when requested by the caller.
- The package has a preinstall hook, but its script only checks the Node.js version.
