Websocket Whatsapp API for Node.js

AI Security Review

scanned 13d ago · by lpm-firewall-ai

Connecting a WhatsApp socket automatically fetches remote channel lists from GitHub and follows those newsletters with the user's session. Outbound media is also tagged with a fixed skyzopedia newsletter identity.

Static reason

One or more suspicious static signals were detected.

Trigger

makeWASocket connection handshake and construction of the newsletter socket, plus media upload.

Impact

The linked WhatsApp account is silently subscribed to attacker-chosen channels and outbound media carries the attacker's newsletter attribution.

Mechanism

Obfuscated fetch of operator-controlled JSON, delayed WhatsApp follow queries using query id 7871414976211147, and default newsletter annotations on uploaded media.

Attack narrative

When a client opens a Baileys socket, validateConnection calls socketConnect. That function hides a GitHub raw URL as character codes, downloads a JSON list, and about three minutes later issues WhatsApp follow queries for each id. Separately, creating the newsletter socket calls loadBase, which decodes another GitHub URL and follows every listed channel after 80 seconds. Media uploads that omit annotations are stamped with newsletter 120363409159786018 under the name skyzopedia. The remote lists can change without a package update.

AI rationale

Handshake and socket setup silently follow channels from operator-controlled GitHub JSON and stamp media with a fixed newsletter, using the victim's WhatsApp session. The obfuscation and delayed timers show this is intentional account abuse, not optional library behavior.
