The published tarball contains no install scripts and no network code; the payload lives in the private dependency, which was not retrieved. Twenty-six such packages under seventeen accounts were published between 2026-07-28 and 2026-10-09.\n\n---\n_-= Per source details.

No install-time, import-time, or runtime code paths that would harm an installer were identified.\n","affected":[{"package":{"name":"tailwind-animatecss-kit","ecosystem":"npm","purl":"pkg:npm/tailwind-animatecss-kit"},"versions":["2.0.6"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"package_integrity":[{"filename":"tailwind-animatecss-kit-2.0.6.tgz","hashes":{"sha1":"c44fe4e900c9aa7ed9f3b34db58dcb25e53bd8fa","sha512_sri":"sha512-0MPZq9NJ0DQykBhAzQ7VbJkwHEGDJ5Swmsh+TZw1Vs2bxqn3TFwtlq4xM8wikrscGPccyEGiIUs0nYSbedL/ug=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/tailwind-animatecss-kit/MAL-2026-18079.json"}}],"references":[{"type":"ADVISORY","url":"https://osv.dev/vulnerability/MAL-2026-17665"},{"type":"ADVISORY","url":"https://osv.dev/vulnerability/MAL-2026-17666"},{"type":"ADVISORY","url":"https://osv.dev/vulnerability/MAL-2026-17667"},{"type":"WEB","url":"https://pkgwarden.com/incidents/fake-interview-tailwind-plugins-npm-october-2026/"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/tailwind-animatecss-kit/v/2.0.6"}],"database_specific":{"iocs":{"files":[{"note":"require of private scoped dependency @jasperquinn/postcss-motion-helpers","paths":["src/motion.js"],"source":"PACKAGE_ARCHIVE"}]},"malicious-packages-origins":[{"id":"IN-MAL-2026-022394","import_time":"2026-10-29T14:37:06.971918172Z","modified_time":"2026-10-29T14:27:07Z","sha256":"d2169471f3936bdf235ec90cf6878b5383d67cb74f013cdcc470365328aa97a3","source":"amazon-inspector","versions":["2.0.6"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"pkgwarden","contact":["https://pkgwarden.com"],"type":"FINDER"}]}
