If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

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.
