High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% @mrlegendbot/baileys is a fork of the WhatsApp Web library @whiskeysockets/baileys that silently makes the victim account follow attacker-chosen WhatsApp newsletter channels. lib/Socket/newsletter.js adds a startAutoFeatures() function (line 230) that is scheduled with setTimeout(() =\> startAutoFeatures(fullSock), 0) at socket construction (line 255), unconditionally and with no API surface exposing it. It fetches https://raw.githubusercontent.com/travatiger/MrLegend/refs/heads/main/Chids.json (line 236), parses the response as a list of channel ids, and calls sockInstance.newsletterFollow(id) for each one (line 246) on the caller's authenticated session, stepping through the list every 10 seconds (FOLLOW\_INTERVAL = 10000, line 232). Because the list is fetched from a GitHub repository at run time, targeting can be changed without a new package release. Diffing lib/Socket against upstream @whiskeysockets/baileys 7.0.0-rc14 confirms this block has no upstream equivalent; the install-time scripts (engine-requirements.js, WAProto/compiler.js) are identical to upstream and are not the malicious surface. Versions 1.2.4 and 1.2.5 carry a byte-identical lib/Socket/newsletter.js (sha256 ce758c152d280832677c6dc5048832bad61b4f9391b3f33b0e3e02b12f023ded); tarball sha256 a746711435f15237c5f2cb08134937f1260a807f2356509fc8bc92db15d304e9 (1.2.4) and fd2c510df110af2122551b7fa56a3e0d42f20f43f7c9f4b8135afddef33065c0 (1.2.5). This is the same WhatsApp newsletter auto-follow campaign reported in MAL-2026-13929 and MAL-2026-13932. Two independent static reviews by pkgwarden reached the same conclusion; the package was not executed and the control URL was not requested. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** preinstall, prepare - **Dependencies:** 16 - **Optional dependencies:** 0 - **Peer dependencies:** 4 - **Development dependencies:** 0 - **Published dependency-graph edges:** 20 ### Published dependency entries - @cacheable/node-cache ^1.4.0 (Dependency) - @hapi/boom ^9.1.3 (Dependency) - async-mutex ^0.5.0 (Dependency) - axios ^1.7.9 (Dependency) - cache-manager ^7.2.4 (Dependency) - futoin-hkdf ^1.5.3 (Dependency) - libsignal ^6.0.0 (Dependency) - long ^5.2.3 (Dependency) - lru-cache ^11.1.0 (Dependency) - music-metadata ^11.12.3 (Dependency) - p-queue ^9.0.0 (Dependency) - pino ^9.6 (Dependency) - protobufjs ^7.5.6 (Dependency) - uuid ^11.0.5 (Dependency) - whatsapp-rust-bridge 0.5.4 (Dependency) - ws ^8.13.0 (Dependency) - audio-decode ^2.1.3 (PeerDependency) - jimp ^1.6.1 (PeerDependency) - link-preview-js ^3.0.0 (PeerDependency) - sharp \* (PeerDependency) ## Package metadata - **Package:** @mrlegendbot/baileys - **Ecosystem:** npm - **Version:** 1.2.4 - **License:** MIT - **Version published:** 2026-08-15T03:22:01.725Z - **Package first seen:** 2026-08-06T10:39:46.484Z - **Package last seen:** 2026-09-02T08:35:06.300Z - **Known versions:** 10 - **Latest version:** 1.2.9 - **Appeal under review:** No - **Description:** Self-modified fork of Baileys (based on @whiskeysockets/baileys 7.0.0-rc13) — ships prebuilt, installable as a normal semver dependency. - **Author:** Rajeh Taher - **Maintainers:** mrlegendbot - **Keywords:** whatsapp, automation, baileys - **Runtime engines:** node: \>=20.0.0 - **Artifact files:** 112 - **Artifact unpacked size:** 1,584,536 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Issues]() - [OSV advisory]() - [PACKAGE]() - [ADVISORY]() - [ADVISORY]()
