{"id":"MAL-2026-18903","summary":"Malicious code in @teamqadeer1/baileys (npm)","details":"@teamqadeer1/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 and then MUTE, so the channel goes unnoticed, for a list downloaded at runtime from https://raw.githubusercontent.com/Qadeer-Xtech/Qadeer-Xtech/main/follow.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).","modified":"2026-11-09T23:15:16.647606714Z","published":"2026-10-27T00:00:00Z","database_specific":{"iocs":{"files":[{"digests":{"sha256":"2a7ea9113d716011aecdf0022b7a7c1f3b4b070bb8a0ab833f3ae62b37534a8a"},"paths":["lib/Socket/newsletter.js"]}],"ips":[],"urls":["https://raw.githubusercontent.com/Qadeer-Xtech/Qadeer-Xtech/main/follow.json"],"domains":["raw.githubusercontent.com"]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@teamqadeer1/baileys"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"@teamqadeer1/baileys","ecosystem":"npm","purl":"pkg:npm/%40teamqadeer1/baileys"},"versions":["1.0.0","1.0.1"],"database_specific":{"cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@teamqadeer1/baileys/MAL-2026-18903.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
