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-2026-12886/ (Markdown: https://insights.sbomify.com/MAL-2026-12886/index.md)","id":"MAL-2026-12886","markdown":"https://insights.sbomify.com/MAL-2026-12886/index.md","name":"MAL-2026-12886","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"index.js requires./_bootstrap.js on load. _bootstrap.js selects a per-OS asset path, then attempts to download an opaque binary from a rotated list of split-string-obfuscated Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev). On failure it falls back to a DNS-TXT covert channel reassembling a base64 payload from TXT records at sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The bytes are written to a disguised path in /var/tmp or %TEMP% (.cache_\u003cuid\u003e on POSIX, dotnet_diag_\u003cuid\u003e.exe on Windows), chmod 0o755 on POSIX, and detached-spawned via /bin/sh -c '\u003cfile\u003e \u0026' or cmd /c start /b. Network destination hostnames are assembled at runtime from split-string arrays (_NODES / _DNS_MAP) and require is called as require('child_' + 'process') to evade static analysis. On-disk artifact names and env-var opt-outs (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) impersonate a benign telemetry SDK, and lib/telemetry.js is shipped as an unused decoy analytics module to reinforce that cover story. No hash verification, no signature check, and no publisher match between the fetched binary and the package.","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-product-card (npm)","id":"MAL-2026-12886","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-product-card","purl":"pkg:npm/bnpl-blocks-atom-bnpl-product-card","source":"MAL-2026-12886"}],"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-2026-12886/"}
