AI Security Review

scanned 3mo ago · by lpm-firewall-ai

The hidden, remote-controlled account modification is concrete runtime behavior, not a scanner-only similarity signal. The install hook itself is benign, but normal package use activates the malicious routine.

Static reason

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

Trigger

Application creates the default socket and its WhatsApp connection reaches open.

Impact

Modifies the user's authenticated WhatsApp subscriptions without consent.

Mechanism

remote-controlled hidden WhatsApp newsletter follow/mute actions

Attack narrative

The default socket stack includes newsletter.js. On every successful connection, it waits 30 seconds, fetches a package-author-controlled list, and follows then mutes each listed newsletter using the user's authenticated WhatsApp session. This is concealed account-state manipulation unrelated to the requested socket operation.

Decision evidence

public snapshot

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

Evidence for block

lib/Socket/newsletter.js fetches a developer-controlled GitHub URL after a WhatsApp connection opens.
It treats the fetched array as newsletter JIDs, then issues FOLLOW and MUTE actions without caller consent.
lib/Socket/messages-send.js constructs this newsletter layer; lib/Socket/index.js exposes that stack as makeWASocket.

Evidence against

engine-requirements.js preinstall only enforces Node.js 20+.
No credential or environment harvesting was found in inspected entrypoints.
messages-media.js network and ffmpeg features are user-invoked media handling.
