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, the code queries DNS TXT records at c.\u003cdomain\u003e under *.dl.wel1.ru for a chunk count, iterates 0.\u003cdomain\u003e..N-1.\u003cdomain\u003e, concatenates the returned strings and base64-decodes them into an executable buffer, providing a covert payload channel that bypasses HTTP egress filtering. Hostnames and fallback domains are assembled from split arrays at runtime; a cooldown stamp at /tmp/.analytics_state and DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK short-circuits present a telemetry cover story around the dropper. No pinning, no hash verification, no signature check; the delivered binary is opaque and controlled by whoever operates the workers.dev tenants and the wel1.ru zone. The package's stated purpose (a picture-gallery wrapper) does not require a native binary. Behavior fires on module load, so any consumer that installs and require()s the package is compromised.","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-picture-gallery (npm)","id":"MAL-2026-12936","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-picture-gallery","purl":"pkg:npm/bnpl-blocks-desktop-bnpl-picture-gallery","source":"MAL-2026-12936"}],"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-2026-12936/"}
