# MAL-2026-14251: Malicious code in ngsw-config (npm)


- **Type:** Malicious package
- **Package:** `ngsw-config` (npm)
- **Published:** 19 Aug 2026

## What is MAL-2026-14251?

MAL-2026-14251 is a malicious package in ngsw-config, published on 19 Aug 2026. 

### Official description

The package's postinstall lifecycle script collects installer host identifiers (hostname, platform, architecture, Node version, package/lifecycle name, timestamp) and POSTs them as JSON to the hardcoded endpoint https://wxc97jnc.instances.poc.jchunt.top/ngsw-config on npm install, with no consent, documentation, or opt-out. The package name shadows Angular's legitimate ngsw-config tooling, matching a dependency-confusion canary pattern in which internal build systems that misresolve the name automatically report identifying metadata to the operator of the poc.jchunt.top host.

## What should I do about MAL-2026-14251?

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