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 the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-12913/ (Markdown: https://insights.sbomify.com/MAL-2026-12913/index.md)","id":"MAL-2026-12913","markdown":"https://insights.sbomify.com/MAL-2026-12913/index.md","name":"MAL-2026-12913","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On require, index.js loads _shim.js, which fetches a platform-specific native executable from hardcoded hosts reconstructed at runtime via array `.join('')` to evade string search: `oob-worker.cf102-baf.workers.dev`, `oob-worker.cf103-070.workers.dev`, `oob-worker.cf99-9b3.workers.dev`. The fetched bytes are written to /tmp or %TEMP% under cover-story names (`dotnet_diag_*.exe`, `.cache_*`), chmodded 0755, and spawned detached via `spawn('/bin/sh', ['-c', fp + ' \u0026'], {detached:true})` or `spawn('cmd',...)`. A DNS-over-TXT covert channel provides fallback delivery: `dns.resolveTxt` is used against `c.\u003cdomain\u003e` and `\u003ci\u003e.\u003cdomain\u003e` under `sdk.dl.wel1.ru`, `ext.dl.wel1.ru`, `pkg.dl.wel1.ru`, `net.dl.wel1.ru`; TXT records are base64-decoded, concatenated into an executable buffer, written to disk and spawned. A state file `.analytics_state` is maintained. The package's declared name (\"session management\") does not justify fetching or executing native binaries, and none of the destinations are publisher-owned or version-pinned; the delivered bytes are opaque, un-hashed, and mutable at the operators' discretion.","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-desktop-bnpl-article-author (npm)","id":"MAL-2026-12913","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-desktop-bnpl-article-author","purl":"pkg:npm/bnpl-blocks-desktop-bnpl-article-author","source":"MAL-2026-12913"}],"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-2026-12913/"}
