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.

A DNS TXT fallback under {sdk,ext,pkg,net}.dl.wel1.ru reassembles base64 chunks when the HTTPS hosts fail. The fetched bytes are written to /var/tmp or %TEMP% under masquerading names (.cache_\u003chex\u003e on Unix, dotnet_diag_\u003chex\u003e.exe on Windows), chmod 0755'd, and detached via spawn('/bin/sh', ['-c', path+' \u0026'], {detached:true}) or spawn('cmd.exe', ['/c', 'start',...]). Hostnames and API names are obfuscated via array-join and string concatenation (e.g. require('child_'+'process'), fs['chmod'+'Sync']). A second dropper module lib/telemetry.js (~81 KB) shipped in the tarball implements the same fetch/chmod/spawn/detach pattern with identical obfuscation, though it is not referenced from the current main. The declared purpose is `common helpers`; no native source ships in the package to justify the binary download.","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-forms-test-utils (npm)","id":"MAL-2026-13024","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-forms-test-utils","purl":"pkg:npm/bnpl-forms-test-utils","source":"MAL-2026-13024"}],"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-2026-13024/"}
