cyberdark-baileys@2.1.6
Blacklord Bail - WhatsApp Web socket library based on Baileys, with branded pairing, rainbow console banner and auto-connect support
AI Security Review
scanned 3h ago · by lpm-firewall-aiThe package automatically uses the consumer’s WhatsApp account to join a publisher-chosen group and follow a publisher-chosen channel when a socket connects. This is an unrequested account action, 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
A consumer creates the package’s default socket and its WhatsApp connection reaches the open state.
Impact
The user’s WhatsApp account joins the publisher-selected group and follows its channel without a request.
Mechanism
The code uses hard-coded invite and channel IDs unless overridden, then calls groupAcceptInvite and newsletterFollow automatically.
Attack narrative
Creating the default socket installs an event handler that joins a hard-coded WhatsApp group and follows a hard-coded channel once the connection opens. These account actions use the consumer’s authenticated WhatsApp socket and occur without an explicit request; they repeat on reconnects.
AI rationale
The package automatically uses the consumer’s WhatsApp account to join a publisher-chosen group and follow a publisher-chosen channel when a socket connects. This is an unrequested account action, so the package is malicious.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The default socket setup arms automatic WhatsApp group joining and channel following, using publisher-selected hard-coded targets when no override is configured.
- When the socket connection opens, the code calls groupAcceptInvite and newsletterFollow without a user request.
- The package’s default makeWASocket constructor reaches the communities socket setup that installs this behavior.
Evidence against
- The package describes itself as a WhatsApp Web socket library, so creating sockets and connecting to WhatsApp are expected features.
- The auto-connect behavior can be overridden through configuration or environment variables, but otherwise uses its hard-coded defaults.
