Which versions of confluent-kafka-javascript are malicious?

The following npm versions of confluent-kafka-javascript are flagged malicious: 0.0.1. Treat any of these as compromised.

How do I remediate confluent-kafka-javascript if I installed it?

confluent-kafka-javascript 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 confluent-kafka-javascript — how do I know if it already compromised me?

If confluent-kafka-javascript 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 confluent-kafka-javascript part of a known attack campaign?

Yes — confluent-kafka-javascript is associated with the GHSA-j28m-58xp-3wgh, IN-MAL-2026-008142 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 confluent-kafka-javascript across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for confluent-kafka-javascript (version 0.0.1).

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall confluent-kafka-javascript

What this malware does

Analysis of this package version produced no static indicator and no traced behavioral findings. The tarball does not exhibit lifecycle-script droppers, credential reads, environment scraping, hardcoded attacker network destinations, or other installer-harm patterns. With no concrete evidence of exfiltration, install-time remote code execution, silent-relay, or backdoor mechanisms in this version's content, there is no basis to block or escalate.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
