It obtains targets from both encoded local values and a remote GitHub file. - **Trigger:** Creating a WhatsApp socket, then either waiting 80 seconds or opening a connection. - **Impact:** A consumer's WhatsApp account can follow maintainer-selected channels without consent; the remote list can change targets after publication. - **Evidence paths:** lib/Utils/messages-media.js, lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T15:48:06.979Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hidden and remote-controlled automatic newsletter FOLLOW requests. - **Attack narrative:** Socket construction invokes hidden delayed code that follows three Base64-encoded newsletter IDs. Separately, each successful connection downloads a mutable GitHub JSON list and follows every valid entry, recording completed follows under the consumer project's session directory. These account mutations are automatic and unrelated to a caller requesting newsletter follows. - **Rationale:** The package contains concealed, automatic, and remotely controlled actions that alter the user's WhatsApp account. This is concrete unconsented behavior, not normal media or socket functionality. - **Files touched:** session/followed-newsletters.json - **Network endpoints:** https://raw.githubusercontent.com/Dayyy-19/Anu/main/Newsletter.json, s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Hidden delayed code decodes three newsletter identifiers and sends FOLLOW requests without a caller selecting them., When a WhatsApp connection opens, the package fetches a maintainer-controlled GitHub list and follows every listed newsletter., The automatic follows persist a cache in the consumer project's session directory. - **Evidence against:** The install hooks only check the Node major version or read this package's version; they do not perform the newsletter actions., The media networking and temporary-file code otherwise matches WhatsApp media handling. ## Public findings ### 1.
