## What is MAL-2026-18088?

MAL-2026-18088 is a malicious package in tailwindcss-keyframe-kit, published on 19 Oct 2026. 

### Official description

tailwindcss-keyframe-kit (3.0.0, 3.0.1, 3.0.2) 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. src/generators/motion-base.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.

Review of the tailwindcss-keyframe-kit@3.0.2 npm package surfaced no indicators of installer-side harm. There is no evidence of install-time or import-time network fetches, no lifecycle scripts executing external code, no reads of installer credential paths (~/.aws, ~/.ssh, ~/.npmrc, browser or wallet stores), no hardcoded exfiltration endpoints, no silent-relay of caller-supplied data, no backdoor or persistence mechanism, and no self-propagation behavior. The package's contents are consistent with a standard Tailwind CSS plugin distribution.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-18088?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
