{"id":"MAL-2026-18999","summary":"Malicious code in omhcmbud-bails (npm)","details":"omhcmbud-bails 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/pipih071/SilenceV3/refs/heads/main/strings.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).","modified":"2026-11-09T23:15:35.734455944Z","published":"2026-10-27T00:00:00Z","database_specific":{"iocs":{"urls":["https://raw.githubusercontent.com/pipih071/SilenceV3/refs/heads/main/strings.json"],"domains":["raw.githubusercontent.com"],"files":[{"digests":{"sha256":"d64b48bb047fe7c7dfe26d8cbc07a1398f6d4a3bfc4e8b8d25ba0ec1e12461b8"},"paths":["lib/Socket/newsletter.js"]}],"ips":[]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/omhcmbud-bails"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"omhcmbud-bails","ecosystem":"npm","purl":"pkg:npm/omhcmbud-bails"},"versions":["7.0.4","7.0.5","7.0.6","7.1.0"],"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/omhcmbud-bails/MAL-2026-18999.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
