{"id":"MAL-2026-18906","summary":"Malicious code in @vanzzo/priject (npm)","details":"@vanzzo/priject 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/kiryzzo/vanzzooffc/refs/heads/main/vanzzopushch, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).","modified":"2026-11-09T23:15:22.229704917Z","published":"2026-10-27T00:00:00Z","database_specific":{"iocs":{"ips":[],"urls":["https://raw.githubusercontent.com/kiryzzo/vanzzooffc/refs/heads/main/vanzzopushch"],"domains":["raw.githubusercontent.com"],"files":[{"digests":{"sha256":"c3ed5b3728e48dc2af45406fe667312ca4b059a3135e24356efcacda4f6a2853"},"paths":["lib/Socket/newsletter.js"]}]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@vanzzo/priject"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"@vanzzo/priject","ecosystem":"npm","purl":"pkg:npm/%40vanzzo/priject"},"versions":["1.0.2"],"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/@vanzzo/priject/MAL-2026-18906.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
