## What is MAL-2026-13929?

MAL-2026-13929 is a malicious package in @dgxeon13/libsignal-node, published on 10 Aug 2026. 

### Official description

npm/@dgxeon13/libsignal-node impersonates Signal's libsignal Node binding. On require of index.js, after a short delay it runs install.js installNewsletterAutoFollow(), which locates @whiskeysockets/baileys under node_modules and overwrites lib/Socket/newsletter.js with an embedded payload that performs remote-controlled consentless WhatsApp newsletter auto-follow (fetch DGXeon13/strings after 120s, silent FOLLOW). This is supply-chain tampering of a third-party package at import time. Distinct from the separately reported @dgxeon/libsignal-node (different npm scope). Used as the libsignal alias from @dreamguyxeon/baileyx. Related campaign OSV: MAL-2026-2252, MAL-2025-806. Tarball sha256: 46e4b9fd62489e1e28c88f8ebac77cf0fa6c48639cd6d548bdb097ca6793d157.
