Which versions of swnwall are malicious?

The following npm versions of swnwall are flagged malicious: 1.2.10. Treat any of these as compromised.

How do I remediate swnwall if I installed it?

Remove swnwall 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 swnwall — how do I know if it already compromised me?

If swnwall 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 swnwall part of a known attack campaign?

Yes — swnwall is associated with the IN-MAL-2026-020075 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 swnwall across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for swnwall (version 1.2.10).

What this malware does

On require/import, index.js invokes initialize() which spawns loader.js as a detached, hidden background child process (detached: true, windowsHide: true, stdio: 'ignore', unref'd) and records a.pid file to avoid re-spawning. loader.js performs an HTTPS GET against https://api.npoint.io/641d37178a880b1e8b8f (a user-editable JSON hosting service), base64-decodes the code field of the response, and executes the decoded payload via new Function("require",..., decodedCode)(require, __dirname, __filename,...), granting the fetched code full access to Node's require, filesystem, and process APIs on the installer's machine. loader.js additionally monkey-patches Module.prototype.require to force windowsHide on all child_process spawn calls and reroute execSync through a hidden cmd.exe /c, concealing further child-process activity. The remote payload is mutable and attacker-controllable via the npoint.io endpoint.
