Summary
Malicious code in gaarf-node (npm)
Details
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.
Decision reason
