Which versions of sorrawit-dev-helper are malicious?

The following npm versions of sorrawit-dev-helper are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate sorrawit-dev-helper if I installed it?

sorrawit-dev-helper is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed sorrawit-dev-helper — how do I know if it already compromised me?

If sorrawit-dev-helper 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 sorrawit-dev-helper part of a known attack campaign?

Yes — sorrawit-dev-helper is associated with the IN-MAL-2026-020228 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 sorrawit-dev-helper across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for sorrawit-dev-helper (version 1.0.0).

What this malware does

package.json declares a postinstall lifecycle script that runs automatically on npm install. The script reads /tmp/flag.txt from the installer's machine and sends its URL-encoded contents as a query parameter to a hardcoded ngrok tunnel at https://ca37-49-237-83-218.ngrok-free.app/. The destination is an ephemeral tunnel host unrelated to any legitimate publisher, and the read+exfil fires without user interaction. The behavior matches install-time credential/file exfiltration with a concrete installer-side data source and a concrete attacker-controlled destination.
