@zanxiky/baileys@1.1.0
A WebSockets library for interacting with WhatsApp Web — iky fork of Baileys
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package silently follows a hard-coded publisher newsletter after ordinary socket creation. This uses the user's WhatsApp account for an action the user did not request, which meets the account-action abuse rule.
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 message socket; the follow is scheduled 150 seconds later.
Impact
Uses the user's WhatsApp account to follow the publisher's chosen newsletter without a request to follow it.
Mechanism
The newsletter socket decodes a hard-coded newsletter ID and sends a FOLLOW mutation through WhatsApp's w:mex query.
Attack narrative
When the normal message socket is created, it constructs a username socket and then a newsletter socket. That socket schedules a request for 150 seconds later, decodes a hard-coded newsletter ID labeled “About Iky,” and sends a WhatsApp FOLLOW mutation. This performs an account action toward a publisher-selected target without the user requesting the follow.
AI rationale
The package silently follows a hard-coded publisher newsletter after ordinary socket creation. This uses the user's WhatsApp account for an action the user did not request, which meets the account-action abuse rule.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- Socket creation schedules a delayed follow request for a hard-coded newsletter labeled “About Iky.”
- The scheduled request decodes the pinned newsletter ID and sends a FOLLOW mutation to WhatsApp.
- The default message socket factory constructs the username socket, which constructs the newsletter socket and triggers the timer.
Evidence against
- The preinstall script only checks the Node.js major version and exits when it is below 20.
- The package describes itself as a WhatsApp Web library, so its WhatsApp protocol traffic otherwise fits its purpose.
