Summary

Malicious code in tailwind-animate-kit (npm)

Details

tailwind-animate-kit (2.0.6, 2.0.7, 2.0.8) 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 keinsell-jh 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 Review

Independent AI assessment: manual_review. LPM AI review remains unresolved.

The inspected package code appears to generate Tailwind styles from Animate.css data, with no confirmed attack behavior. The active style-generation path invokes an unresolved runtime dependency, so its behavior cannot be verified.

Static reason

No blocking static signals were detected.

Trigger

Using the exported Tailwind plugin to generate styles.

Impact

The helper's behavior cannot be assessed from the available source, so this review cannot establish that the full active path is benign.

Mechanism

The plugin invokes a PostCSS helper whose source could not be inspected in this snapshot.

AI rationale

Evidence

package.jsonplugin.jssrc/motion.js

Independent scan evidence

public snapshot

AI called this Manual Review at 84.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json declares @jasperquinn/postcss-motion-helpers as a runtime dependency.
The exported plugin reaches buildStyles, which invokes the helper through PostCSS while generating styles; the helper source was unavailable in the supplied snapshot.

Evidence against

The inspected plugin and style code builds Tailwind CSS output from Animate.css data and showed no confirmed attack behavior.
