MAL-2026-18086

Summary: Malicious code in tailwindcss-animatemotion (npm)

Details: tailwindcss-animatemotion (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 doublekk61 on 2026-09-28. src/motion.js:5 requires the private scoped package @aaron205whitmore/postcss-animate-utils, 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 (f1875d701acced7256cfa2d34bc1ced617af4ac7f4568414d547f8525e989e70) Package [email protected] (npm) contains no observed behavior consistent with a supply-chain attack. No install-time or import-time network fetch-and-execute, no credential or environment-variable harvesting, no writes to installer secret paths, no lifecycle scripts performing privileged or destructive actions, and no hardcoded attacker-controlled endpoints were identified in the shipped files.
