# MAL-2026-18062: Malicious code in sc-wizard (npm)


- **Type:** Malicious package
- **Package:** `sc-wizard` (npm)
- **Published:** 20 Oct 2026

## What is MAL-2026-18062?

MAL-2026-18062 is a malicious package in sc-wizard, published on 20 Oct 2026. 

### Official description

package.json declares the package's only dependency `ltidisafe` as a direct HTTPS tarball URL (`https://ltidi.storage.googleapis.com/depenconf/ltidisafe-4.0.1.tgz`) rather than a registry version range. On `npm install`, npm fetches that URL and installs whatever bytes it returns, executing any lifecycle scripts contained in the fetched tarball — unpinned, integrity-unchecked, and outside the npm registry's publish controls. The shipped `index.js` is an empty stub, so the manifest-declared off-registry URL is effectively the entire install-time payload. The dependency source is a mutable third-party storage bucket; whoever controls that URL controls code running on the installer's machine at install time. The high version number (`99.9.1`) relative to a short, generic name is consistent with a dependency-confusion lure intended to win resolution against an internal `sc-wizard` package.

The OpenSSF Package Analysis project identified 'sc-wizard' @ 99.9.1 (npm) as malicious.

It is considered malicious because:

- The package communicates with a domain associated with malicious activity.

## What should I do about MAL-2026-18062?
