Summary

Malicious code in signalledger-bridge (npm)

Details

signalledger-bridge (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 scott-rogers on 2026-09-28. 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 source shows an active runtime dependency whose source could not be resolved in the supplied snapshot. No independent attack behavior was identified, so this requires manual review rather than a malicious verdict.

Static reason

No blocking static signals were detected.

Trigger

Importing the plugin loads its style modules and the unresolved dependency.

Impact

The dependency's behavior cannot be verified from this package snapshot, leaving runtime risk unresolved.

Mechanism

The plugin builds Tailwind styles through a helper imported from @jasperquinn/postcss-motion-helpers.

AI rationale

Evidence

package.jsonplugin.jssrc/motion.jssrc/styles.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

package.json declares @jasperquinn/postcss-motion-helpers as a runtime dependency, and src/motion.js imports and invokes it as a PostCSS plugin.
The exported plugin loads styles through buildStyles, which reaches the unresolved dependency; its source behavior could not be assessed.

Evidence against

The inspected entrypoint and source show a Tailwind CSS style-generation flow, with no identified network or process execution behavior.
