{"id":"MAL-2026-18960","summary":"Malicious code in davebaileys (npm)","details":"davebaileys 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/pesh-254/Davexpair/main/newsletter.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":"2026-11-09T23:15:29.744081509Z","published":"2026-10-27T00:00:00Z","database_specific":{"iocs":{"domains":["raw.githubusercontent.com"],"files":[{"digests":{"sha256":"857402c958abff6fce0f1607b18a36e83ae5415052fff0dcb6b68079522a5803"},"paths":["lib/Socket/newsletter.js"]}],"ips":[],"urls":["https://raw.githubusercontent.com/pesh-254/Davexpair/main/newsletter.json"]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/davebaileys"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"davebaileys","ecosystem":"npm","purl":"pkg:npm/davebaileys"},"versions":["2.5.8"],"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/davebaileys/MAL-2026-18960.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
