How do I remediate cardano-addresses-docs if I installed it?

Remove cardano-addresses-docs from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

What this malware does

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.
