Summary

Malicious code in tailwindcss-animate-catalog (npm)

Details

tailwindcss-animate-catalog (2.0.6, 2.0.7) 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 hackson306623 on 2026-09-28. lib/styles/variables.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 package source connects style generation to a scoped registry dependency whose source is unavailable in this snapshot. That unresolved executable boundary prevents a clean determination, but the inspected source does not establish malicious behavior.

Static reason

No blocking static signals were detected.

Trigger

Tailwind invokes the plugin callback to generate styles.

Impact

The dependency's behavior cannot be determined from this snapshot, leaving its runtime effects unresolved.

Mechanism

Style generation calls buildVariables, which invokes the unresolved scoped dependency as a PostCSS plugin.

AI rationale

Evidence

package.jsonindex.jslib/styles/index.jslib/styles/variables.js

Independent scan evidence

public snapshot

AI called this Manual Review at 91.0% confidence as Unknown with medium false-positive risk.

AI review observations

package.json declares the unresolved registry dependency @jasperquinn/postcss-motion-helpers at ^1.0.1.
Plugin style generation calls buildVariables, which loads and invokes that dependency as a PostCSS plugin; its source is unavailable for review.
