High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% @modss/baileys is a renamed fork of the Baileys WhatsApp Web library published 2026-09-01 and 2026-09-02 under a scope created the same day. lib/Socket/newsletter.js sets NEWSLETTER\_LIST\_URL to https://raw.githubusercontent.com/Dayyy-19/Anu/main/Newsletter.json. On every connection.update with connection === 'open', autoFollowConfiguredNewsletters() fetches that list and issues an executeWMexQuery FOLLOW for each id on the user's own authenticated WhatsApp session, caching followed ids in session/followed-newsletters.json. An Indonesian comment in the file explains that the list lives on GitHub so channels can be added or removed without redeploying the code, i.e. the follow targets are publisher-controlled at runtime. All three published versions carry the identical handler. The package also aliases its libsignal dependency to @modss/libsignal, which pkgwarden read as a plain rename with no malicious content. No credential or session-key theft was observed, and the dead-drop URL was not requested by pkgwarden. All versions were fetched from the npm registry and read by hand on 2026-09-03. Same remote-dead-drop shape as MAL-2026-15819 (@mrlegendbot/baileys) and MAL-2026-13932 (my-auto-follow). ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall, preinstall - **Dependencies:** 23 - **Optional dependencies:** 0 - **Peer dependencies:** 3 - **Development dependencies:** 12 - **Published dependency-graph edges:** 26 ### Published dependency entries - @cacheable/node-cache \* (Dependency) - @hapi/boom \* (Dependency) - @modss/libsignal ^1.0.0 (Dependency) - @whiskeysockets/eslint-config github:whiskeysockets/eslint-config (Dependency) - async-mutex \* (Dependency) - axios \* (Dependency) - cache-manager \* (Dependency) - figlet \* (Dependency) - fs \* (Dependency) - gradient-string 2.0.2 (Dependency) - jimp 0.22.12 (Dependency) - lodash \* (Dependency) - lru-cache \* (Dependency) - moment-timezone \* (Dependency) - music-metadata \* (Dependency) - os \* (Dependency) - p-queue \* (Dependency) - path \* (Dependency) - pbjs ^0.0.14 (Dependency) - pino \* (Dependency) - protobufjs \* (Dependency) - readline \* (Dependency) - ws \* (Dependency) - audio-decode \* (PeerDependency) - better-sqlite3 ^11.0.0 (PeerDependency) - link-preview-js \* (PeerDependency) ## Package metadata - **Package:** @modss/baileys - **Ecosystem:** npm - **Version:** 1.0.1 - **License:** MIT - **Version published:** 2026-09-02T00:26:07.951Z - **Package first seen:** 2026-09-03T15:48:06.979Z - **Package last seen:** 2026-09-04T06:20:06.873Z - **Known versions:** 3 - **Latest version:** 1.0.2 - **Appeal under review:** No - **Description:** Websocket Whatsapp API for Node.js - **Author:** Dayyy - **Maintainers:** modss - **Keywords:** whatsapp, websocket, api, nodejs, baileys, wabot, proto, whatsapp-websocket - **Runtime engines:** node: \>=20.0.0 - **Artifact files:** 109 - **Artifact unpacked size:** 5,680,652 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Issues]() - [OSV advisory]() - [PACKAGE]() - [ADVISORY]() - [ADVISORY]() - [WEB]()
