AI Security Review

scanned 2d ago · by lpm-firewall-ai

The runtime source establishes an automatic follow of a package-selected newsletter on connection, an unrequested authenticated account action. This supports blocking the package; the install-time Node version check does not explain or authorize that 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

The WhatsApp connection reaches the open state.

Impact

The account is made to follow a publisher-selected newsletter without a user-requested action.

Mechanism

The newsletter socket decodes a hardcoded newsletter identifier and sends a follow query using the account's authenticated connection.

Attack narrative

When the connection opens, the package decodes a fixed newsletter identifier and issues a follow query. The newsletter socket is instantiated in the exported socket stack, and the query travels through the authenticated WhatsApp service path. This performs an account action the caller did not request.
