{"id":"MAL-2026-18811","summary":"Malicious code in @bmbxmd/baileys (npm)","details":"@bmbxmd/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://files.gifted.co.ke/file/chJids.json (the URL itself stored as base64 strings), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).","modified":"2026-11-09T23:15:20.534555756Z","published":"2026-10-27T00:00:00Z","database_specific":{"iocs":{"domains":["files.gifted.co.ke"],"files":[{"digests":{"sha256":"c5fd93d838a136067d6bc89d5df6e2433cfa693ff13fe5fe44dc8bcd3a3c5180"},"paths":["lib/Socket/newsletter.js"]}],"ips":[],"urls":["https://files.gifted.co.ke/file/chJids.json"]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@bmbxmd/baileys"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"@bmbxmd/baileys","ecosystem":"npm","purl":"pkg:npm/%40bmbxmd/baileys"},"versions":["2.5.8"],"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/@bmbxmd/baileys/MAL-2026-18811.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
