Summary
Malicious code in giantswarm (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (75f3a244f2761c56347f695897a491d23ab04cafe1e5b0e46fd7d0d2c993f828)

The package declares a preinstall hook (node index.js) that runs automatically on npm install. index.js collects host reconnaissance — hostname, platform, arch, home directory, username/uid/gid/shell, whoami, id, and cwd — and POSTs the collected data as JSON to a hardcoded Burp Collaborator subdomain at https://w305i20ui5s5476lc3b998z28tek2bq0.oastify.com/detox56. The package ships with empty description, author, and license fields and no functional code beyond the beacon. The unscoped name giantswarm impersonates the Giant Swarm vendor namespace, consistent with a dependency-confusion attack targeting private @giantswarm/* scopes.
