@zyrennofficiall/baileys@5.4.0
A WebSockets library for interacting with WhatsApp Web.
AI Security Review
scanned 2h ago · by lpm-firewall-aiThe package automatically follows hard-coded publisher-selected WhatsApp channels when its socket is created, using the user's account. This is an unauthorized account action and warrants blocking publication.
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 socket; the top-level follow runs when the connection opens, and four more follows are scheduled during newsletter socket construction.
Impact
Subscribes the user's WhatsApp account to channels the user did not choose.
Mechanism
Calls WhatsApp newsletter-follow operations for hard-coded channel IDs. The top-level follow can be disabled with autoFollow: false, but the four scheduled follows are unconditional.
Attack narrative
Socket creation triggers follows of publisher-selected WhatsApp channels through the user's account: one when the connection opens and four more scheduled by the newsletter socket. The top-level follow has an opt-out, but the four scheduled follows are unconditional. This performs account actions toward targets chosen by the publisher without the user's request.
AI rationale
The package automatically follows hard-coded publisher-selected WhatsApp channels when its socket is created, using the user's account. This is an unauthorized account action and warrants blocking publication.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The default connection config sets autoFollow to true.
- When the socket connection opens, makeWASocket follows a hard-coded publisher-selected WhatsApp channel.
- Socket construction reaches makeNewsletterSocket, which schedules automatic follows of four additional hard-coded newsletter IDs using WhatsApp's FOLLOW query.
- The preinstall script only checks that Node.js is version 20 or later.
Evidence against
- The package describes itself as a WhatsApp Web library, so connecting to WhatsApp is expected.
- The top-level auto-follow behavior has an opt-out, though the four scheduled newsletter follows do not use it.
