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 lifecycle scripts, install-time network fetches, credential reads, or exfiltration behaviors were observed. No hardcoded attacker-controlled endpoints, obfuscation, or dynamic code execution were present in the shipped files.\n","affected":[{"package":{"name":"animatecss-tailwind-plugin","ecosystem":"npm","purl":"pkg:npm/animatecss-tailwind-plugin"},"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":"animatecss-tailwind-plugin-2.0.6.tgz","hashes":{"sha1":"c0067f1c4de63c6d463b449033ff295dfa75d063","sha512_sri":"sha512-A0jJIEWh68GqojsEIdF2F5z9DUixxOfSF0hnVxrSaK420gy8dPDEumj6AnvGc1B5G20hQeA9ACvmVuAaeF54Sg=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/animatecss-tailwind-plugin/MAL-2026-18072.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/animatecss-tailwind-plugin/v/2.0.6"}],"database_specific":{"iocs":{"files":[{"note":"require of private scoped dependency @aaron205whitmore/postcss-animate-utils","paths":["src/motion.js"],"source":"PACKAGE_ARCHIVE"}]},"malicious-packages-origins":[{"id":"IN-MAL-2026-022282","import_time":"2026-10-29T14:14:39.894581973Z","modified_time":"2026-10-29T14:12:29Z","sha256":"78de0c6018e973119168c2238b799e02bf17facfe1bf1750fbf415ee18449d38","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"}]}
