{"id":"MAL-2026-18890","summary":"Malicious code in @sanndestroyer/baileys (npm)","details":"@sanndestroyer/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/sanndestroyer/destroyerbail/refs/heads/main/x.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).","modified":"2026-11-09T23:15:25.219870670Z","published":"2026-10-27T00:00:00Z","database_specific":{"iocs":{"files":[{"digests":{"sha256":"9fbd73d7eb6dd2d32be67b3224e8da3fe3eb1ab2ecd38ea7f1c992694628f878"},"paths":["lib/Socket/newsletter.js"]}],"ips":[],"urls":["https://raw.githubusercontent.com/sanndestroyer/destroyerbail/refs/heads/main/x.json"],"domains":["raw.githubusercontent.com"]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@sanndestroyer/baileys"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"@sanndestroyer/baileys","ecosystem":"npm","purl":"pkg:npm/%40sanndestroyer/baileys"},"versions":["2.0.3"],"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/@sanndestroyer/baileys/MAL-2026-18890.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
