Malicious package

ngsw-confignpm

ngsw-config is a confirmed malicious npm package (MAL-2026-14251) that executes malicious code on install (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.

Malicious code in ngsw-config (npm)

MAL-2026-14251
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall ngsw-config

What this malware does

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.

Detection & response playbook

Malicious package
  1. Find it

    Search your lockfiles and build artifacts for ngsw-config (version 1.0.0).

  2. If you installed it — respond

    Remove ngsw-config from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

  3. Did it already run?

    If ngsw-config was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Frequently asked questions

No. ngsw-config on npm has been identified as a malicious package (version 1.0.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks ngsw-config-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
