It fetches attacker-selected newsletter IDs and follows them through the consumer's WhatsApp session. - **Trigger:** Creating a newsletter socket, followed by the built-in 80-second delay. - **Impact:** The package can alter the user's WhatsApp newsletter subscriptions without an explicit follow request. - **Evidence paths:** lib/Utils/messages-media.js, lib/Socket/newsletter.js, lib/Types/Newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-10T11:54:33.186Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote list fetch followed by automatic WhatsApp newsletter follows. - **Attack narrative:** When a consumer creates a newsletter socket, the package calls loadBase. After 80 seconds, that function decodes and fetches a GitHub-hosted JSON list, then invokes the WhatsApp newsletter follow query for every remotely supplied ID. The operation is silent and catches errors, so it can change the logged-in account's subscriptions without a user request. - **Rationale:** This is a concealed, remotely controlled account-action mechanism unrelated to normal media handling. The direct call path from socket construction to automatic follows makes the behavior concrete. - **Files touched:** lib/Utils/messages-media.js, lib/Socket/newsletter.js, lib/Types/Newsletter.js - **Network endpoints:** https://raw.githubusercontent.com/Fyxzpediaa/Deobfuscated-Tools/main/AVg.json, @s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** A delayed hidden routine decodes a remote GitHub URL and fetches JSON., Each remote JSON item causes a follow request using its supplied ID., Newsletter socket creation invokes that routine with its WhatsApp query function and the follow query ID. - **Evidence against:** No credential harvesting or local secret exfiltration was found in the inspected files., Install hooks only enforce the Node version and print a banner., The other network and file operations inspected support WhatsApp media handling. ## Affected versions and remediation This report applies to @fyxzpediaa/baileys@9.0.0. - Avoid installing @fyxzpediaa/baileys@9.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
