Summary
Malicious code in animate-tailwind-kit (npm)
Details
animate-tailwind-kit (3.0.1, 3.0.4) 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 johnxia1997 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.
Independent LPM AI assessment
Manual ReviewIndependent AI assessment: manual_review. LPM AI review remains unresolved.
The inspected package source shows a Tailwind CSS plugin and no install lifecycle script, but a required runtime dependency is unresolved and is called during style generation. Its behavior cannot be cleared from the available source, so manual review is appropriate.
Static reason
No blocking static signals were detected.
Trigger
Tailwind invokes the plugin callback while building styles.
Impact
The helper's behavior cannot be assessed from the available source, so a clean verdict is not supported.
Mechanism
Style generation loads `@jasperquinn/postcss-motion-helpers` and calls it through PostCSS; the dependency source was unavailable in the supplied snapshot.
AI rationale
The inspected package source shows a Tailwind CSS plugin and no install lifecycle script, but a required runtime dependency is unresolved and is called during style generation. Its behavior cannot be cleared from the available source, so manual review is appropriate.
Evidence
src/motion.js
Independent scan evidence
public snapshotAI called this Manual Review at 83.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The manifest declares `@jasperquinn/postcss-motion-helpers` as a runtime dependency.
- The plugin calls `buildStyles` during Tailwind plugin execution, and style generation invokes the helper.
- The available source snapshot does not include that dependency's source, so its behavior remains unresolved.
Evidence against
- The inspected manifest lists lint and test scripts, with no install lifecycle script shown.
