The destination is assembled at call-time from a numeric array rather than appearing as a plain-text literal, which is a deliberate concealment technique on the message-send code path where WhatsApp session data and outbound message content are handled. Obfuscated construction of a non-first-party destination inside the messaging pipeline of a WhatsApp client library is the shape of session/message exfiltration to an author-controlled endpoint.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in @sahril2nd/baileys (npm)","id":"MAL-2026-16105","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"@sahril2nd/baileys","purl":"pkg:npm/%40sahril2nd/baileys","source":"MAL-2026-16105"}],"products":null,"published":"2026-09-09","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-16105/"}
