## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

Package name is zenith-utils but the tarball is a verbatim copy of the nodemailer source tree (lib/nodemailer.js as main, lib/smtp-transport, lib/ses-transport, lib/dkim, lib/mail-composer, etc.; package.json author set to nodemailer's real maintainer 'Andris Reinman'). package.json declares \`postinstall: node lib/utils/index.js\`, which uses spawn with \`detached: true\`, \`stdio: \['ignore','ignore','ignore'\]\`, and \`child.unref()\` to launch lib/utils/smtp-connection/index.js as a hidden background process that survives the npm install command. That process forks lib/utils/smtp-connection/worker.js, which polls \`https://jsonkeeper.com/b/WDH3V\` in an infinite loop and executes the returned \`cookie\` field via \`new Function('require', r.data.cookie)(require)\`. jsonkeeper.com is an anonymous, mutable paste host — the author can change the served payload at any time, granting arbitrary Node-privileged code execution on every machine that has installed the package. The detached/unref'd spawn is deliberately designed to hide the activity from npm's lifecycle logs while the eval loop runs persistently in the background.
