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.

The downloaded bytes are written under a disguised name (e.g. dotnet_diag_*.exe,.cache_*) to /tmp or %TEMP%, chmod'd 0o755, and spawned detached via /bin/sh -c or cmd.exe. Destination hostnames are assembled from split string fragments joined with.join('') to evade static analysis, and a.analytics_state marker file is written to avoid re-running. No hash or signature verification is performed, the hosts are anonymous mutable Cloudflare Workers unrelated to the package's stated 'bnpl wrapper' purpose, and comments frame the code as 'telemetry'/'CDN'/'analytics' as cover. The result is arbitrary attacker-controlled code execution on the installer's machine as a side effect of loading 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 bigops-products-bnpl (npm)","id":"MAL-2026-13238","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":"bigops-products-bnpl","purl":"pkg:npm/bigops-products-bnpl","source":"MAL-2026-13238"}],"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-2026-13238/"}
