Summary

Malicious code in tailwind-kinetic (npm)

Details

tailwind-kinetic (2.0.6, 2.0.8) 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 keinsell-jh on 2026-09-28. src/motion.js:5 requires the private scoped package @aaron205whitmore/postcss-animate-utils, 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 uses the unresolved dependency in its runtime style-generation path. Since its source was unavailable, the dependency's behavior cannot be resolved from this inspection; this is not evidence of a confirmed attack.

Static reason

No blocking static signals were detected.

Trigger

Tailwind invokes the package plugin callback to build styles.

Impact

The dependency's potential effects remain unknown; the inspected source does not establish an attack.

Mechanism

Style generation calls a PostCSS utility from a runtime dependency whose source was unavailable for inspection.

AI rationale

Evidence

package.jsonsrc/motion.jsplugin.js

Independent scan evidence

public snapshot

AI called this Manual Review at 94.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest declares @aaron205whitmore/postcss-animate-utils as a runtime dependency.
The motion module imports that dependency and invokes it while building the PostCSS processor.
The plugin entrypoint reaches style building when Tailwind invokes the plugin callback.

Evidence against

The dependency source could not be inspected, so its runtime behavior and safety remain unresolved.
