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 retrieval fails, a fallback channel uses DNS TXT queries against *.dl.wel1.ru (c.\u003cdomain\u003e for chunk count, i.\u003cdomain\u003e for base64-encoded chunks) to reassemble the payload out-of-band. The downloaded bytes are written to /var/tmp or %TEMP% under deceptive names such as dotnet_diag_\u003crand\u003e.exe and.cache_\u003crand\u003e, chmod'd 0755, and executed detached via /bin/sh -c \"\u003cpath\u003e \u0026\" or cmd.exe /c start. No hash or signature verification is performed. The advertised purpose (\"bnpl title provider\") has no relation to any of this behavior. A second file, lib/telemetry.js, is not currently required but contains structurally identical dropper primitives (base64 payload assembly, chmod 0755 via bracket-split property name, /bin/sh detached spawn of a downloaded file), staged for activation by a one-line require change.","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-title (npm)","id":"MAL-2026-12945","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-title","purl":"pkg:npm/bnpl-blocks-desktop-bnpl-title","source":"MAL-2026-12945"}],"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-2026-12945/"}
