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 fetching or executing remote content were observed, no reads of installer credential paths (~/.aws, ~/.ssh, ~/.npmrc, browser profiles) or environment scraping, no hardcoded exfiltration endpoints, no obfuscated payloads, and no silent-relay of caller-supplied data. Behavior is consistent with a small Tailwind CSS animation utility package.\n","affected":[{"package":{"name":"animate-tailwind-kit","ecosystem":"npm","purl":"pkg:npm/animate-tailwind-kit"},"versions":["3.0.1","3.0.4"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"package_integrity":[{"filename":"animate-tailwind-kit-3.0.1.tgz","hashes":{"sha1":"88faebd44596191d322acd778b417a96599e047b","sha512_sri":"sha512-/0GO+26xCLn8Mr35XAU2bLJXlRF4yS9x/X/mi9FOrHGIV+4r346l+R0InRsGoj5kOHkd1AACm6YAQj6vKjBoXg=="}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/animate-tailwind-kit/MAL-2026-18065.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/animate-tailwind-kit/v/3.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/animate-tailwind-kit/v/3.0.4"}],"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-2026-022384","import_time":"2026-10-29T14:37:06.589221787Z","modified_time":"2026-10-29T14:25:54Z","sha256":"13c04524c3a3794d7e6fe909621fcc9521081c11230330a97dfb8b83a3c48e81","source":"amazon-inspector","versions":["3.0.1"]},{"id":"IN-MAL-2026-022374","import_time":"2026-10-29T14:37:06.233057894Z","modified_time":"2026-10-29T14:24:31Z","sha256":"b8fff3160d492e2390af5e937dad42639cafb3cdaa5dad6e0bf3bd4f175478c7","source":"amazon-inspector","versions":["3.0.4"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"pkgwarden","contact":["https://pkgwarden.com"],"type":"FINDER"}]}
