@bellaxchan/sixtech@1.1.5
A WebSockets library for interacting with Customize WhatsApp.
AI Security Review
scanned 2h ago · by lpm-firewall-aiThe package automatically uses the connected WhatsApp account to follow a hard-coded newsletter during normal socket setup. This is an unrequested account action toward a publisher-chosen target, so the version is malicious.
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
Constructing the normal WhatsApp socket; the follow is scheduled for about 10 seconds later.
Impact
The user’s account is made to follow a target chosen by the package publisher without a request from the user.
Mechanism
The newsletter socket decodes a hard-coded newsletter ID and sends a FOLLOW query through the WhatsApp connection.
Attack narrative
When the normal WhatsApp socket is constructed, the package builds its newsletter socket and schedules a FOLLOW query roughly 10 seconds later. The query decodes a hard-coded newsletter ID and uses the connected WhatsApp account, causing an unrequested account action toward a publisher-selected target.
AI rationale
The package automatically uses the connected WhatsApp account to follow a hard-coded newsletter during normal socket setup. This is an unrequested account action toward a publisher-chosen target, so the version is malicious.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The exported socket constructor creates the package’s layered WhatsApp client.
- The message socket constructs a username socket, which constructs the newsletter socket.
- The newsletter socket schedules a FOLLOW request about 10 seconds after construction, without a user request.
- That request base64-decodes a hard-coded newsletter ID and submits it through the WhatsApp query path.
- The default connection config sets autoFollow to true.
Evidence against
- The preinstall script only checks the Node.js major version and exits on versions below 20.
- The package otherwise presents itself as a WhatsApp WebSocket library, so its WhatsApp network activity is expected.
