If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The destination host and the `os`/`dns`/`process` module names are obfuscated in `lib/c5df9a.js` and `lib/b4ce8f.js` using char-code byte arrays (`String.fromCharCode`) and loaded via `module.constructor._load` instead of plain `require`, concealing both the APIs and the C2 destination. The obfuscation and DNS-label-encoded channel are inconsistent with the package's presentation as a shared web assets helper.","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 @shared-web/assets (npm)","id":"MAL-2026-16283","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":"@shared-web/assets","purl":"pkg:npm/%40shared-web/assets","source":"MAL-2026-16283"}],"products":null,"published":"2026-09-18","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-2026-16283/"}
