Campaign includes a chain of dependencies that finally exfiltrate sensitive environment variables to a hardcoded GitHub repository as exfiltration target, and in specific environments also start a reverse shell. It appears to be targeting specifically one GitHub project, where the front-end package was included in a PR.
