AI Security Review
scanned 7d ago · by lpm-firewall-aiThe package automatically uses the connected WhatsApp account to follow newsletters chosen by a remote list controlled by the publisher. This is an unsolicited 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
Normal construction of the message socket, followed by the user's WhatsApp connection opening.
Impact
Uses the connected account to follow targets chosen by the package publisher without the user's request.
Mechanism
The newsletter socket fetches a Base64-obscured channel list from raw.githubusercontent.com, then sends WhatsApp MEX follow requests for each listed newsletter ID.
Attack narrative
When normal message-socket construction reaches the newsletter socket, it fetches a publisher-controlled list of newsletter IDs. Once the user's WhatsApp connection opens, it schedules follow requests for every listed ID through the authenticated WhatsApp connection, without requiring the user to request or approve those follows.
AI rationale
The package automatically uses the connected WhatsApp account to follow newsletters chosen by a remote list controlled by the publisher. This is an unsolicited account action, so the package is malicious.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package's main export points to its JavaScript client entry point.
- Constructing the message socket constructs the username socket, which constructs the newsletter socket.
- The newsletter socket decodes a hard-coded URL for a remote channel list.
- The socket fetches that list automatically and accepts newsletter IDs from it.
- After the WhatsApp connection opens, it schedules follow requests for each listed ID without an explicit user request.
Evidence against
- The package is a WhatsApp Web client, and it provides an explicit newsletter-follow API.
- The observed follow requests go to WhatsApp through its normal MEX query mechanism; the separate remote request retrieves the list of targets.
