{"id":"MAL-2026-18966","summary":"Malicious code in dibosockets (npm)","details":"dibosockets 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 the channel ID(s) 120363403828324716@newsletter, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).","modified":"2026-11-09T23:15:31.399316375Z","published":"2026-10-27T00:00:00Z","database_specific":{"iocs":{"urls":[],"domains":[],"files":[{"digests":{"sha256":"34801125545955bd542a9e09c7ea34ec134535e86484ff0585a0e344144bb763"},"paths":["lib/Socket/newsletter.js"]},{"digests":{"sha256":"50816cf9d9d94ae34c12ef95f84fd72d46e5b9e0962920db3e2f72129bf9a9ca"},"paths":["lib/Socket/newsletter.js"]}],"ips":[]}},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dibosockets"},{"type":"WEB","url":"https://www.ox.security/blog/phantomsub-malicious-npm-campaign-secretly-adds-users-to-whatsapp-spam-channels/"}],"affected":[{"package":{"name":"dibosockets","ecosystem":"npm","purl":"pkg:npm/dibosockets"},"versions":["1.0.2","1.0.4","1.0.5","1.0.6","1.0.7","1.0.8","1.0.9","1.1.0"],"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/dibosockets/MAL-2026-18966.json"}}],"schema_version":"1.9.2","credits":[{"name":"CyberXYZ","contact":["https://cyberxyz.io"],"type":"FINDER"}]}
