AI Security Review
scanned 2d ago · by lpm-firewall-aiThe runtime performs an automatic, publisher-selected account action when the connection opens. The preinstall hook is only a Node.js version check, but it does not mitigate the unsolicited follow behavior.
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
A socket created with the package connects successfully.
Impact
The authenticated account is subscribed to a publisher-selected newsletter without the user requesting that action.
Mechanism
The newsletter socket decodes a hard-coded newsletter identifier and sends a follow query to WhatsApp.
Attack narrative
Creating a socket reaches the newsletter socket through the package’s exported socket constructor. Once the connection opens, the newsletter code decodes a fixed identifier and sends a follow query to WhatsApp. This changes the authenticated account’s subscriptions without a caller-selected target or an explicit request to follow that newsletter.
AI rationale
The runtime performs an automatic, publisher-selected account action when the connection opens. The preinstall hook is only a Node.js version check, but it does not mitigate the unsolicited follow behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- Importing the package exposes its socket constructor, which flows through the socket layers to the newsletter socket.
- The newsletter socket waits for an open connection, then decodes a hard-coded newsletter identifier and issues a follow request without caller input or consent.
- The request is sent through the WhatsApp service query mechanism.
- The package has a preinstall hook, but its script only checks the Node.js version.
Evidence against
- The preinstall hook only checks whether Node.js is version 20 or newer and exits on older versions.
