@bil-rgb/baileys@1.0.1
A WebSockets library for interacting with WhatsApp Web — bil-rgb fork of Baileys
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe standard socket creation path automatically follows a hard-coded publisher-selected WhatsApp newsletter using the user's authenticated account. This is an unrequested account action.
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
Creating the standard WhatsApp socket; the action runs after a 150-second delay.
Impact
Changes the user's WhatsApp account by subscribing it to the publisher's chosen channel without consent.
Mechanism
Decodes a hard-coded newsletter JID and sends a WhatsApp newsletter FOLLOW query.
Attack narrative
Creating the normal socket stack reaches makeNewsletterSocket, which schedules a follow request 150 seconds later. It decodes a hard-coded newsletter identifier labeled “My Channel” and sends the FOLLOW operation over the user's WhatsApp connection, changing the account without an explicit request.
AI rationale
The standard socket creation path automatically follows a hard-coded publisher-selected WhatsApp newsletter using the user's authenticated account. This is an unrequested account action.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- Constructing the normal socket stack reaches makeNewsletterSocket through makeMessagesSocket and makeUsernameSocket.
- makeNewsletterSocket schedules a follow request 150 seconds after creation, without an explicit user request.
- The follow target is hard-coded in Base64, decoded, and labeled “My Channel”; the code sends it with the FOLLOW operation.
Evidence against
- The preinstall script only checks the Node.js major version and exits on unsupported versions.
- The newsletter request uses the existing WhatsApp query mechanism.
