Summary

Malicious code in my-auto-follow (npm)

Details

npm/my-auto-follow is a Baileys WhatsApp Web API fork that embeds undisclosed, remote-controlled consentless newsletter auto-follow behavior. In lib/Socket/newsletter.js, after a session is established the code waits 120 seconds, fetches a JSON list of WhatsApp newsletter JIDs from https://raw.githubusercontent.com/DGXeon13/strings/refs/heads/main/strings.json (attacker-controlled; observed contents include newsletter JIDs), and silently issues newsletterWMexQuery(..., QueryIds.FOLLOW) for each entry with errors swallowed. There is no caller opt-in. Trigger is runtime (makeNewsletterSocket / normal socket path), not install: preinstall only checks Node >= 20. The package also depends on libsignal via the npm alias npm:@dreamguyxeon/libsignal-node@1.0.1 (separate malicious patcher reported alongside this entry). Related DGXeon campaign packages already in OSV include dgxeon-baileys (MAL-2026-2252) and baileys-dgxeon (MAL-2025-806). Tarball sha256 for 1.0.3: 1332d396a2251692c2654fca52620a433a880551500a567ade040e8f01440e68.

my-auto-follow@1.0.6 is a Baileys WhatsApp library fork with two installer-affecting behaviors. First, package.json declares the dependency whatsapp-rust-bridge-baron as git+https://github.com/7ucg/whatsapp-rust-bridge.git with no commit SHA or tag pin; the tarball ships no bundled node_modules for it, so npm install resolves the git URL at install time and executes whatever code and lifecycle hooks the HEAD of that repository contains, entirely outside the installer's version pinning and integrity control. Second, makeNewsletterSocket in the package's default socket construction schedules a 120-second timer that fetches a channel-ID list from https://raw.githubusercontent.com/DGXeon13/strings/refs/heads/main/strings.json (an unpinned mutable branch on a personal GitHub account) and issues WhatsApp newsletter FOLLOW queries for each ID using the caller's authenticated WhatsApp session, inflating the author's channel subscribers using the installer's identity. This behavior is not disclosed in README, and the target list can be changed remotely at any time by whoever controls that repository.
