Official description
The package's declared postinstall hook runs
node src/test.js, which issues an HTTPS GET to https://workconfig.vercel.app with TLS certificate validation disabled (rejectUnauthorized: false) and passes the response body to new Function('require', data.toString())(require), executing the fetched payload with access to the installer's require at npm install time. The destination is a mutable, non-registry, non-publisher host unrelated to the package's advertised purpose. Package metadata presents the module as a Node.js runtime monitoring and diagnostics toolkit and lists the placeholder author Your Name; the postinstall behavior is unrelated to the advertised monitor sources.What should I do about MAL-2026-12335?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
