## What is MAL-2026-12493?

MAL-2026-12493 is a malicious package in utility-kit-ts, published on 5 Aug 2026. 

### Official description

The package's default export getPlugin issues a fetch to the hardcoded bare-IP URL https://31.97.137.157:45000/icons/109 and passes the returned data.credits field to the Function constructor, then invokes the compiled function with require, module, process, Buffer and other Node primitives bound in. Any code the remote host returns executes in the caller's Node.js process with full library privileges. A separate function setDefaultModule constructs a plausible cdnjs/font-awesome URL from an icon-domain map but is never called from any export, serving as decoy alongside the actual bare-IP eval sink. The package is advertised in its README as a zero-dependency TypeScript utility toolkit, but package.json declares dependencies (@primno/dpapi for Windows DPAPI unwrap, better-sqlite3, node-machine-id, socket.io-client, request) that are inconsistent with utility helpers and are pre-staged for the fetched payload to require — the building blocks of a credential/browser-cookie stealer.

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-2026-12493?

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