AI Security Review
scanned 2d ago · by lpm-firewall-aiThe runtime source establishes an automatic, publisher-selected account action on connection, which is concrete attack behavior under the review policy. The normal WhatsApp destination does not make that unsolicited subscription user-authorized.
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 consumer creates a socket and its WhatsApp connection opens.
Impact
The user’s account is changed by subscribing to a publisher-selected newsletter without consent to that specific action.
Mechanism
A connection callback decodes a package-selected newsletter identifier and sends a follow query without a caller-provided target.
Attack narrative
Creating a socket leads to an automatic follow request when the WhatsApp connection opens. The callback supplies a fixed, encoded newsletter identifier and sends the follow operation through the authenticated WhatsApp protocol. This changes the consumer’s account by subscribing it to a package-selected newsletter without consent to that action.
AI rationale
The runtime source establishes an automatic, publisher-selected account action on connection, which is concrete attack behavior under the review policy. The normal WhatsApp destination does not make that unsolicited subscription user-authorized.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- When the WhatsApp connection opens, the socket decodes a fixed newsletter identifier and automatically sends a follow request.
- The request sends the follow operation and its newsletter identifier through the WhatsApp protocol query.
- The package exports makeWASocket, which constructs the socket layers containing this connection callback.
- The default socket connects to WhatsApp Web, matching the destination of the account action.
Evidence against
- The request uses the package’s normal authenticated WhatsApp connection; the inspected code does not show an unrelated recipient or credential transfer.
