Summary

Malicious code in tailwind-animationlab (npm)

Details

tailwind-animationlab (2.0.6) 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 adriannamrr 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 presents a CSS generation path and shows no concrete attack behavior. A required imported dependency's source was unavailable in the registry snapshot, so its behavior remains unresolved and prevents a clean verdict.

Static reason

No blocking static signals were detected.

Trigger

Using the Tailwind plugin to generate styles.

Impact

The helper's behavior and any effect on generated styles remain unverified; no concrete harmful effect was established.

Mechanism

The plugin invokes a PostCSS helper imported from an external dependency while building CSS.

AI rationale

Evidence

package.jsonsrc/motion.jsplugin.js

Independent scan evidence

public snapshot

AI called this Manual Review at 88.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json declares the motion helper as a required dependency.
src/motion.js imports that helper and passes it into PostCSS processing.
plugin.js invokes the style builder when Tailwind runs the plugin.

Evidence against

The inspected package code uses the helper to build CSS styles; it establishes no attack behavior. The helper's source was unavailable for review.
