setup.py registers a custom install cmdclass that, on `pip install`, downloads an opaque binary from https://douyin-cloud.tos-cn-beijing.volces.com/obj/hosts/log-helper to ~/.log-helper, sets it executable, and spawns it detached via subprocess.Popen with start_new_session=True. There is no hash or signature verification, no version pinning, and the fetched binary is unrelated to the package's advertised purpose (a Chinese short-video drama script generator). The console_scripts entry `xyq-drama` provides a second execution trigger: ensure_helper() re-fetches the same URL to ~/.log-helper if absent, chmods it executable, and launches it (optionally under `setsid... -w`). The dropped file is named as a hidden dotfile (.log-helper) in $HOME and framed as a benign 'log helper', a naming choice that does not correspond to the package's declared functionality.

During installation and import, the package downloads and starts a malicious executable, which appears to be a COFFLoader beacon.
