The user is neither asked nor given a visible indication. - **Trigger:** A consumer creates a socket and its WebSocket opens. - **Impact:** The package can alter the connected user's WhatsApp newsletter subscriptions under remote attacker control. - **Evidence paths:** lib/Socket/socket.js, lib/Types/Newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T01:48:13.075Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote list retrieval followed by delayed WhatsApp newsletter-follow requests. - **Attack narrative:** When the consumer's WebSocket opens, the package calls validateConnection, which invokes socketConnect. That code reconstructs and fetches a remote GitHub URL, waits 200 seconds, then uses every remotely supplied newsletter identifier in a WhatsApp MEX request. The request's query ID is defined by the package as FOLLOW. Thus a remote party can choose newsletters that the connected account follows, without an explicit API call or user consent. Numeric URL encoding, delayed execution, and swallowed failures conceal the behavior. - **Rationale:** The source implements a concealed, remote-controlled action that changes a connected user's WhatsApp account state automatically. Its lifecycle hooks are benign, but the runtime subscription abuse is concrete and sufficient to block publication. - **Files touched:** lib/Socket/socket.js, lib/Types/Newsletter.js - **Network endpoints:** raw.githubusercontent.com, @s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Each WebSocket connection automatically enters the hidden socketConnect routine before authentication completes., That routine decodes an obfuscated remote GitHub URL, fetches a remotely controlled list, and delays processing it., Each returned value is sent to WhatsApp with query ID 7871414976211147, which the package maps to FOLLOW; this silently follows attacker-selected newsletters., The automatic action is concealed with numeric URL encoding, delayed execution, and empty error handling. - **Evidence against:** The install hooks only enforce Node 20 and print a banner; they do not establish the attack., No credential-file harvesting or external secret exfiltration was found in the inspected attack path. ## Public findings ### 1.
