Summary

Malicious code in tailwindcss-visual-kit (npm)

Details

tailwindcss-visual-kit (0.0.0-stage, 1.3.6) 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 johnsmith0821 on 2026-10-09. 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 unresolved runtime dependency in its style-generation path. Because its source could not be verified, the dependency behavior remains unresolved; the available source does not establish an attack.

Static reason

No blocking static signals were detected.

Trigger

Using this package’s Tailwind plugin to build styles.

Impact

The unresolved helper behavior prevents confirming whether this code path is benign; no specific harmful effect was established.

Mechanism

The plugin invokes a PostCSS helper while generating motion styles, but the helper’s source was unavailable for inspection.

AI rationale

Evidence

package.jsonplugin.jssrc/motion.js

Independent scan evidence

public snapshot

AI called this Manual Review at 78.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest declares @jasperquinn/postcss-motion-helpers as a runtime dependency.
The Tailwind plugin reaches the motion module through its style-building path.
The motion module imports the helper and passes its result to PostCSS as a plugin; the helper’s source could not be verified.

Evidence against

The inspected package code uses the helper while generating PostCSS styles; no attack behavior was established in the inspected code.
