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

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.
