AI Security Review

scanned 3d ago · by lpm-firewall-ai

Source inspection confirms that socket creation activates an automatic follow of a hardcoded channel when the connection opens. This is a publisher-selected account action, so the package should be blocked.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

The caller creates a socket and its WhatsApp connection opens.

Impact

The connected account is made to follow the selected channel without an explicit caller request.

Mechanism

The socket setup registers a connection handler that schedules a follow of a hardcoded channel ID.

Attack narrative

Creating a socket registers a handler that runs when the WhatsApp connection opens. The handler follows a channel whose ID is hardcoded in the package; the caller’s configuration does not select or enable that action. This causes an unrequested change to the connected account.

AI rationale

Evidence

lib/index.jslib/Socket/index.jslib/Utils/auto-follow.js

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

The package entrypoint exports the socket factory used to create WhatsApp connections.
Creating a socket unconditionally registers the automatic follow behavior.
When the connection opens, the handler schedules a follow and calls the account action with a fixed channel ID.
The fixed channel is embedded in the package and does not depend on the caller’s configuration.
