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.

Destination hostnames are assembled by joining split string fragments to evade static detection. The fetched bytes are written to /tmp or %TEMP% under a disguised name (dotnet_diag_\u003crnd\u003e.exe on Windows,.cache_\u003crnd\u003e on Unix), chmodded 0755, and spawned detached via cmd.exe or /bin/sh -c with unref(). A TTL marker file suppresses re-execution and a DISABLE_TELEMETRY environment variable acts as an opt-out cover story. A second, parallel dropper implementation is bundled at lib/telemetry.js disguised as an analytics SDK (base64 chunk assembly, chmod 755, /bin/sh -c spawn of a decoded file path); it is not on the currently reachable require() path but ships in the tarball as a secondary payload runner.","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-loans (npm)","id":"MAL-2026-13242","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-loans","purl":"pkg:npm/bigops-products-loans","source":"MAL-2026-13242"}],"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-2026-13242/"}
