{"id":"MAL-2026-18867","summary":"Malicious code in @ndikafath/baileys (npm)","details":"@ndikafath/baileys is a fork of the Baileys WhatsApp Web library that silently subscribes the installer's own WhatsApp account to WhatsApp Channels chosen by the publisher. When the socket connects, code in lib/Socket/newsletter.js sends the WhatsApp w:mex FOLLOW query for a list downloaded at runtime from https://raw.githubusercontent.com/neofetch25/ID-Channel/refs/heads/main/idChannel.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).","modified":"2026-11-09T23:15:22.433585542Z","published":"2026-10-27T00:00:00Z","database_specific":{"iocs":{"ips":[],"urls":["https://raw.githubusercontent.com/neofetch25/ID-Channel/refs/heads/main/idChannel.json"],"domains":["raw.githubusercontent.com"],"files":[{"digests":{"sha256":"0ed027964ac3d42e01310f210b734f17d97dc15648201931d89ea56d4e17e2f2"},"paths":["lib/Socket/newsletter.js"]}]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@ndikafath/baileys"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"@ndikafath/baileys","ecosystem":"npm","purl":"pkg:npm/%40ndikafath/baileys"},"versions":["1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@ndikafath/baileys/MAL-2026-18867.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
