AI Security Review

scanned 7d ago · by lpm-firewall-ai

Source inspection confirms an automatic account action: the normal socket constructor follows a fixed publisher-selected newsletter. This is concrete unauthorized account mutation, so publication should be blocked.

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

Calling the package’s socket constructor starts the follow routine; it also retries after the connection opens.

Impact

The authenticated account is subscribed to a publisher-selected channel without the caller choosing that target.

Mechanism

The routine sends a follow query for a hard-coded newsletter ID through the WhatsApp network.

Attack narrative

The public socket constructor reaches the newsletter socket, which starts a background routine that follows a fixed channel when the socket is created and again after connection opens. The routine retries if needed. This changes the authenticated account’s subscriptions without the caller selecting the channel.
