{"id":"MAL-2026-18884","summary":"Malicious code in @risaoffc/baileys (npm)","details":"@risaoffc/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/clarssafaqih-rgb/clarissa/refs/heads/main/risa.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).","modified":"2026-11-09T23:15:24.248558407Z","published":"2026-10-27T00:00:00Z","database_specific":{"iocs":{"files":[{"paths":["lib/Socket/newsletter.js"],"digests":{"sha256":"80693ad69a6c8d40def3436eb3ad4bd14527226c5f3f0bd048b4b20cfca4c12e"}}],"ips":[],"urls":["https://raw.githubusercontent.com/clarssafaqih-rgb/clarissa/refs/heads/main/risa.json"],"domains":["raw.githubusercontent.com"]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@risaoffc/baileys"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"@risaoffc/baileys","ecosystem":"npm","purl":"pkg:npm/%40risaoffc/baileys"},"versions":["8.0.0","8.0.1","8.0.2","8.0.3"],"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/@risaoffc/baileys/MAL-2026-18884.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
