AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The source contains a concrete, automatic and remotely directed modification of a user's WhatsApp account rather than a package-aligned feature invoked by the caller. The install hook is benign, but it does not mitigate the runtime abuse.

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 WhatsApp socket and its connection opens.

Impact

Unconsented modification of the user's WhatsApp newsletter subscriptions with concealed notifications.

Mechanism

remote-controlled automatic newsletter follow-and-mute actions

Attack narrative

At runtime, the newsletter socket registers a connection-open listener. Thirty seconds after a user connects their WhatsApp account, it fetches a JSON list from the maintainer's GitHub content URL. Each valid newsletter ID is then sent through WhatsApp follow and mute operations. This is not exposed as a user-requested API action and lets the remote list change subscription targets without a new package release.

Decision evidence

public snapshot

AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.

Evidence for block

The runtime socket layer fetches a remotely controlled newsletter-ID list and follows each listed channel.
It installs this action on every successful WhatsApp connection, delayed 30 seconds, without caller opt-in.
The package mutes channels after following them, concealing the unsolicited account changes.

Evidence against

The preinstall hook only rejects Node versions below 20.
The dynamic import and ffmpeg spawn are media-processing helpers, not this behavior's delivery mechanism.
No credential or local-file harvesting was found in the inspected lifecycle and newsletter paths.
