It also enumerates process.env keys and filters them against a broad credential-name regex set (token, secret, key, password, aws, azure, gcp, npm, ssh, private, credential, jwt, bearer, stripe, db, mysql, postgres, mongo, redis). The collected payload is POSTed to api.telegram.org via a hardcoded Telegram Bot API token and chat_id (1064260758). A secondary DNS-based side channel base64-encodes host/user/CI fields and issues a `dns.resolve` against a `\u003cencoded\u003e.dc-callback.example.com` subdomain as a fallback for environments that block HTTPS to Telegram. The package presents itself as a byted/commerce materials module and a `security research / dependency confusion PoC`; the self-label does not change that the traced behavior harvests installer host and credential reconnaissance and ships it off-host to attacker-controlled channels without consent.","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 byted-commerce-materials (npm)","id":"MAL-2026-16326","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":"byted-commerce-materials","purl":"pkg:npm/byted-commerce-materials","source":"MAL-2026-16326"}],"products":null,"published":"2026-09-21","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-2026-16326/"}
