Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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 binary is written to /tmp or %TEMP% under disguised names (.cache_\u003crnd\u003e, dotnet_diag_\u003crnd\u003e.exe), chmodded to 0755, and spawned detached via /bin/sh -c or cmd.exe /c start. No hash or signature verification is performed and the destinations have no relation to the package's stated purpose. Destination hostnames, DNS resolver domains, and sensitive API names (child_process, chmodSync) are assembled at runtime from split string fragments to evade static analysis, and a hidden-dot stamp file with cover-story labels ('analytics_state', 'telemetry') plus an EXPIRE_SEC re-run gate is used. A parallel dropper implementation is bundled in lib/telemetry.js using dynamic child_process import, base64 chunk assembly, /bin/sh spawn, and chmodSync 0755, framed as an 'analytics SDK'.","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-radio (npm)","id":"MAL-2026-12888","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-radio","purl":"pkg:npm/bnpl-blocks-atom-bnpl-radio","source":"MAL-2026-12888"}],"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-2026-12888/"}
