@zhengliyoux/baileys@1.0.4
A WebSockets library for interacting with WhatsApp Web
AI Security Review
scanned 6d ago · by lpm-firewall-aiThe package automatically uses the connected WhatsApp account to follow a fixed newsletter when a socket connects. This is an unsolicited account action toward a publisher-selected target, so the package is malicious.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
The application calls makeWASocket and its WhatsApp connection opens, unless ZHENGLIYOUX_NO_FOLLOW is set.
Impact
The user's connected WhatsApp account is subscribed to a publisher-selected channel without a request to follow it.
Mechanism
A registered connection listener calls newsletterFollow with the package's hard-coded newsletter ID, issuing a WhatsApp FOLLOW action.
Attack narrative
Creating a socket registers a listener that waits for the WhatsApp connection to open, then follows the hard-coded newsletter ID through a WhatsApp FOLLOW query. This uses the user's connected account for an unsolicited subscription to a target chosen by the package publisher. An environment variable can disable the action, but it is enabled by default.
AI rationale
The package automatically uses the connected WhatsApp account to follow a fixed newsletter when a socket connects. This is an unsolicited account action toward a publisher-selected target, so the package is malicious.

Decision evidence
public snapshotAI called this Malicious at 97.0% confidence as Malware with low false-positive risk.
Evidence for block
- Every call to makeWASocket registers autoFollow on the created socket.
- When the WhatsApp connection opens, autoFollow calls newsletterFollow with a fixed channel ID; the only opt-out is an environment variable.
- newsletterFollow sends the channel ID through the WhatsApp newsletter FOLLOW query.
