Summary: Malicious code in f0-data-constructor (npm)

Details: Source: amazon-inspector (23fc7101aab5c7172a2ab40e0e1ce62dbd251d5301f5efb5f4c30cab065bb5cd) The package's preinstall hook auto-executes index.js on `npm install`. The script imports `https` and `os`, collects `os.hostname()`, `os.platform()`, `os.arch()`, `os.homedir()`, and `dns.getServers()`, and POSTs the JSON payload to the hardcoded host `rb6etzw0lznpijvfl5m5ujmyrpxhl99y.oastify.com` at path `/hit`. oastify.com is Burp Collaborator out-of-band infrastructure; the subdomain uniquely identifies the operator's Collaborator session. The behavior matches a dependency-confusion / typosquat reconnaissance beacon: no documented package purpose, no consent, and the collected fields exist solely to identify the installer host to the operator.
