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 executes attacker-controlled JavaScript with full `require` access under the installer's Node process. A base64-encoded backup endpoint and secret header key are stored in `lib/const.js` (decoding to a second jsonkeeper.com paste URL with an `x-secret-key` header), providing a redundant delivery channel. Because jsonkeeper.com is a mutable public paste site, the served payload can be changed at any moment. The logger API is a cover story for the dropper.","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 notifier-log (npm)","id":"MAL-2026-10153","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":"notifier-log","purl":"pkg:npm/notifier-log","source":"MAL-2026-10153"}],"products":null,"published":"2026-07-10","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-2026-10153/"}
