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 ReviewIndependent AI assessment: manual_review. LPM AI review remains unresolved.
The package source shows a CSS plugin workflow and no install lifecycle hook, but a selected runtime dependency could not be verified. That unresolved dependency prevents a clean verdict; the inspected source does not establish malicious behavior.
Static reason
No blocking static signals were detected.
Trigger
Importing the plugin loads its style modules; invoking the plugin builds CSS styles.
Impact
The dependency's behavior remains unassessed, so its possible effects cannot be established from the inspected source.
Mechanism
The style code imports the dependency and invokes it as a PostCSS plugin while generating variables; its implementation was unavailable for inspection.
AI rationale
The package source shows a CSS plugin workflow and no install lifecycle hook, but a selected runtime dependency could not be verified. That unresolved dependency prevents a clean verdict; the inspected source does not establish malicious behavior.

Independent scan evidence
public snapshotAI called this Manual Review at 76.0% confidence as Unknown with medium false-positive risk.
AI review observations
- package.json declares @jasperquinn/postcss-motion-helpers as a runtime dependency.
- The plugin builds styles through lib/styles/variables.js, which imports and invokes that dependency.
Evidence against
- The manifest lists lint and test scripts, with no install lifecycle script.
- The inspected code uses the dependency to generate CSS variables; no attack behavior was confirmed.
