Malicious code in cardano-addresses-docs (npm)

package.json declares a preinstall hook (node index.js) that runs automatically on npm install. index.js collects host identifiers (os.hostname(), os.userInfo(), homedir, DNS servers, __dirname, full package.json) and reads /etc/passwd and /etc/hosts from the installer's machine, then HTTPS-POSTs the JSON payload to swsusmhg43tobo96re8dwn0vomudi46t.oastify.com — a Burp Collaborator out-of-band domain. The package has empty author, empty description, no real functionality, and a name impersonating the legitimate cardano-addresses Cardano library — consistent with a dependency-confusion / typosquat reconnaissance payload.
