Summary
Malicious code in @carvana.authentication-flows/shared (npm)
Details

package.json declares a preinstall hook (node index.js) that runs unconditionally on npm install. index.js imports child_process/os/https, collects host identifiers (os.hostname, os.userInfo, platform, arch, homedir, cwd) and shells out to whoami/id, then POSTs the collected JSON to a hardcoded Burp Collaborator subdomain at https://pleq9pugrugzr4zgyymazmnq0h68u4it.oastify.com/detox56. The package name also impersonates the Carvana org by using a . in the scope (@carvana.authentication-flows/shared), making carvana.authentication-flows a fake top-level npm scope rather than a Carvana-owned namespace. There is no legitimate functionality shipped; the package's sole effect on install is reconnaissance exfiltration to an attacker-controlled out-of-band server.
