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 uses the helper in its CSS generation path, but the required dependency source was unavailable for review. This unresolved executable dependency warrants manual review; it does not establish malicious behavior.

Static reason

No blocking static signals were detected.

Trigger

Tailwind invokes the exported plugin callback during stylesheet processing.

Impact

The helper's behavior cannot be assessed from the available source snapshot.

Mechanism

The callback generates styles through src/motion.js, which imports and calls the unresolved helper dependency.

AI rationale

Evidence

package.jsonsrc/motion.jsplugin.js

Independent scan evidence

public snapshot

AI called this Manual Review at 86.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest declares @jasperquinn/postcss-motion-helpers as a required runtime dependency.
src/motion.js imports that helper and invokes it while creating the PostCSS processor.
The plugin entrypoint reaches style generation when Tailwind invokes the plugin callback.
