Summary

Malicious code in tailwindcss-motionanimate (npm)

Details

tailwindcss-motionanimate (1.0.1) 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 @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 source follows a CSS plugin path, but a required helper on that active path has unresolved registry source. This prevents a clean verdict without independently establishing malicious behavior.

Static reason

No blocking static signals were detected.

Trigger

The Tailwind plugin callback runs during Tailwind configuration processing.

Impact

The helper's behavior cannot be assessed from this snapshot, so the runtime review is incomplete.

Mechanism

The callback builds styles, and that path invokes the unavailable helper as a PostCSS plugin.

AI rationale

Evidence

src/motion.jspackage.jsonplugin.js

Independent scan evidence

public snapshot

AI called this Manual Review at 98.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json declares @jasperquinn/postcss-motion-helpers as a required runtime dependency.
src/motion.js imports and invokes that helper to build PostCSS output; its source was unavailable for inspection.
plugin.js reaches the style-building path when the Tailwind plugin runs.

Evidence against

The inspected entry point and source describe generating Tailwind CSS styles; no attack behavior was identified in those excerpts.
