Summary

Malicious code in tailwind-animaflow-kit (npm)

Details

tailwind-animaflow-kit (2.0.6) 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 killerdev1127 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 inspected code follows the package’s stated Tailwind animation purpose, but a directly imported runtime dependency was unresolved and its source could not be reviewed. This leaves a material source gap, so manual review is appropriate.

Static reason

No blocking static signals were detected.

Trigger

Tailwind invokes the plugin callback while processing its configuration.

Impact

The dependency’s behavior could not be verified, so the review cannot establish whether this path is benign.

Mechanism

The callback builds styles through a motion helper that imports and invokes an unavailable dependency.

AI rationale

Evidence

src/motion.jspackage.jsonplugin.js

Independent scan evidence

public snapshot

AI called this Manual Review at 83.0% confidence as Unknown with medium false-positive risk.

AI review observations

The manifest declares an animation utility dependency that could not be resolved for source inspection.
The plugin invokes its style builder when Tailwind runs the plugin callback.
The motion builder imports the unresolved dependency and calls it to create CSS processing behavior.

Evidence against

The inspected entrypoint builds styles and registers them with Tailwind; no separate attack behavior was identified in that path.
