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.

No hash or signature verification is performed. A second copy of the dropper is shipped in lib/telemetry.js (labeled as an 'Analytics SDK') using the same shape with split-string API names such as require('child_'+'process') and fs['chmod'+'Sync']; it is not wired into the current entry point but stages the same capability. The destination hosts are not first-party to the package, and the string-splitting plus DNS-TXT channel are anti-analysis tradecraft rather than legitimate telemetry configuration.","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 bnpl-blocks-atom-bnpl-popup (npm)","id":"MAL-2026-12885","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":"bnpl-blocks-atom-bnpl-popup","purl":"pkg:npm/bnpl-blocks-atom-bnpl-popup","source":"MAL-2026-12885"}],"products":null,"published":"2026-08-05","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-2026-12885/"}
