{"id":"MAL-2026-18685","summary":"Malicious code in aemeath-baileys (npm)","details":"aemeath-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, lib/autofollow-newsletters.js sends the WhatsApp w:mex FOLLOW query and then MUTE, so the channel goes unnoticed, for the channel ID(s) 120363410056240594@newsletter, 120363412837402275@newsletter, 120363417661721059@newsletter, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).","modified":"2026-11-05T05:15:04.111494637Z","published":"2026-10-26T00:00:00Z","database_specific":{"iocs":{"files":[{"digests":{"sha256":"30f9b68d846b2add825cce6d2551aaf02ea64107b1de8f26aa08cf781925219d"},"paths":["lib/Socket/newsletter.js"]},{"digests":{"sha256":"8233ef6dce8ee165c827908412a3fa4333e94b1719ccd6d1803fa47c304dd8e0"},"paths":["lib/autofollow-newsletters.js"]}],"ips":[],"urls":[],"domains":[]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/aemeath-baileys"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"aemeath-baileys","ecosystem":"npm","purl":"pkg:npm/aemeath-baileys"},"versions":["1.1.13"],"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/aemeath-baileys/MAL-2026-18685.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
