Which versions of gaarf-node are malicious?

The following npm versions of gaarf-node are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate gaarf-node if I installed it?

gaarf-node establishes remote access, so treat any host that installed it as fully compromised. Isolate the machine, remove the package, rotate all credentials it could reach, and rebuild from a trusted image rather than cleaning in place — a backdoor may have planted additional persistence.

I already installed gaarf-node — how do I know if it already compromised me?

If gaarf-node 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 gaarf-node part of a known attack campaign?

Yes — gaarf-node is associated with the IN-MAL-2026-018339 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 gaarf-node across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for gaarf-node (version 1.0.0).

npm uninstall gaarf-node

What this malware does

The package's postinstall script runs automatically on npm install and collects host identifiers (os.hostname(), platform, arch, node version, package name, npm lifecycle event) and POSTs them as JSON to the hardcoded remote host ze0buq23.instances.poc.jchunt.top at path /gaarf-node. The package name impersonates Google's ads-api-report-fetcher (gaarf) project referenced in source.txt, while package.json self-labels as a Security research canary. The destination domain is unrelated to the impersonated Google project, and the outbound beacon fires with no user consent as a lifecycle side effect of installation.
