@axo_cuy/baileyss@1.0.0
A WebSockets library for interacting with WhatsApp Web.
AI Security Review
scanned 2h ago · by lpm-firewall-aiThe package silently follows a hard-coded WhatsApp channel when its normal socket is created, using the user's account for an action they did not request. The preinstall hook is only a Node.js version check, but it does not mitigate the automatic runtime 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 normal socket through the package's runtime API; the action is scheduled for 10 seconds later.
Impact
The user's account follows a channel they did not choose or request.
Mechanism
The newsletter socket decodes a hard-coded channel ID and submits a FOLLOW query through the WhatsApp connection.
Attack narrative
When the ordinary socket factory builds the newsletter layer, a timer schedules a WhatsApp FOLLOW query for the hard-coded channel 120363412451922209@newsletter. It uses the user's connected account without an explicit request, promoting a target selected by the package publisher.
AI rationale
The package silently follows a hard-coded WhatsApp channel when its normal socket is created, using the user's account for an action they did not request. The preinstall hook is only a Node.js version check, but it does not mitigate the automatic runtime account action.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- Creating the normal messages socket constructs the username and newsletter socket layers, reaching the newsletter setup automatically.
- Newsletter socket construction schedules a follow action after 10 seconds for a hard-coded channel ID that decodes to 120363412451922209@newsletter.
- The follow request is sent through the WhatsApp query protocol over the user's connected account.
- The preinstall script only checks whether Node.js is version 20 or newer.
Evidence against
- No install-time collection or unrelated network contact was identified.
- The package is a WhatsApp WebSocket library, so its WhatsApp connection and user-invoked account operations fit its stated purpose.
