    Summary: Malicious code in tailwind-css-keyframes (npm)

    Details: tailwind-css-keyframes (1.0.7) is a Tailwind CSS plugin from the fake job interview campaign behind MAL-2026-17665 and MAL-2026-17666: the same Animate.css integration template, README and description, published by kinsley_badu on 2026-09-28. src/motion.js:5 requires the private scoped package @jasperquinn/postcss-motion-helpers, which is not readable on the public registry and resolves only with the npm token committed in the lure repository's web/.npmrc, so the code it delivers runs when tailwind.config.js loads the plugin and the dev server starts. 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. Source: amazon-inspector (e859eaecef067fc4ab7faa25927f15ed5158be6f58103f6aea3f151e4ebd9e78) The package contains no behavior indicative of a supply-chain attack against installers. No install-time or import-time network fetches, credential access, environment scraping, or code execution paths were observed. No lifecycle scripts, hardcoded external endpoints, or obfuscated payloads are present.
