Summary
Malicious code in gaarf (npm)
Details
The package's postinstall lifecycle script runs automatically on npm install and collects installer host identifiers (os.hostname(), platform, arch, Node version, package name, lifecycle event) and POSTs them to the hardcoded host n8wx863s.instances.poc.jchunt.top at path /gaarf. The destination is not the installer's infrastructure and is not caller-configurable. The package name 'gaarf' matches the short name of google/ads-api-report-fetcher, so installs are most likely typos of that package; the beacon fires on those mistaken installs and reports the mistyping host to a third-party endpoint.
Decision reason
OpenSSF Malicious Packages via OSV confirms gaarf@3.2.1 as malicious (MAL-2026-14236): Malicious code in gaarf (npm)
