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.

The gem declares an extension script in its gemspec that executes during `gem install`. On install, the script collects installer identity and local system data — current working directory, home directory, hostname, username, and the contents of /etc/resolv.conf, /etc/passwd, and /etc/hosts — and POSTs them over TLS via a raw TCPSocket to the hardcoded Burp Collaborator subdomain bjyhowqsve7p6i4fflj14mly8pel2bq0.oastify.com on port 443. The exfiltration is unrelated to the gem's stated 'simple demo' purpose and runs automatically on default install.
