## What is MAL-2026-6580?

MAL-2026-6580 is a malicious package in loadutils, published on 29 Jun 2026. 

### Official description

Package `loadutils` is a typosquat of the widely-used webpack helper `loader-utils`. The shipped README documents the loader-utils API (`urlToRequest`, `interpolateName`, `getHashDigest`), but `src/index.js` instead exports a `debug`-style logger — name, documentation, and implementation do not align. On import, `src/index.js` executes `require('debug-glitzs')` at the top level, but `debug-glitzs` is not declared in `dependencies`, `peerDependencies`, or `optionalDependencies`; whatever resolves to that name in the installer's tree runs in the Node.js process as soon as `loadutils` is required. `package.json` additionally declares `lessload@^1.0.1` as a runtime dependency that is never referenced in `src/` and is unrelated to either the logger code or the advertised loader-utils API, pulling further unaccounted code into the installer's dependency tree on `npm install`. The `contributors` metadata also impersonates a well-known maintainer (`Kiko Beats` paired with an unrelated homepage `alphacointech1010.com`), reinforcing the deceptive packaging.

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-2026-6580?

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