# MAL-2026-12815: Malicious code in widget-forge (npm)


- **Type:** Malicious package
- **Package:** `widget-forge` (npm)
- **Published:** 5 Aug 2026

## What is MAL-2026-12815?

MAL-2026-12815 is a malicious package in widget-forge, published on 5 Aug 2026. 

### Official description

widget-forge@9999.0.0 is a dependency-confusion beacon. package.json declares scripts.preinstall = 'node callback.js', which auto-runs on npm install. callback.js collects os.hostname(), os.userInfo().username, process.cwd(), npm_config_registry, and CI repository identifiers (GITHUB_REPOSITORY and related CI env vars) and sends them via HTTP GET to the hardcoded bare-IP endpoint http://75.119.137.232:31337/depconfuse?pkg=.... The package has no functional payload: main is an empty object export, the description is a generic placeholder, and the version 9999.0.0 is the pattern used to outbid internal package versions in dependency-confusion attacks. The only effect of installation is the recon callback to the hardcoded IP.

## What should I do about MAL-2026-12815?

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