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.

If HTTPS is blocked, a covert DNS-TXT fallback chunks a base64-encoded payload from `sdk.dl.wel1.ru`, `ext.dl.wel1.ru`, `pkg.dl.wel1.ru`, and `net.dl.wel1.ru`. Destination hostnames and.ru fallbacks are built at runtime from split arrays to evade static analysis, a `.analytics_state` cache stamp suppresses re-runs, and DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK env-var checks provide a telemetry cover story. lib/telemetry.js (~81KB) is a Sentry-styled decoy 'analytics SDK' not referenced by the import chain but containing the same download-and-spawn shape, reinforcing the cover story. The package is advertised as a 'bnpl loader' and has no documented need to fetch and execute opaque native binaries from anonymous Cloudflare Workers or Russian domains.","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-loader (npm)","id":"MAL-2026-13530","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-loader","purl":"pkg:npm/bnpl-blocks-atom-bnpl-loader","source":"MAL-2026-13530"}],"products":null,"published":"2026-08-07","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-2026-13530/"}
