On `pip install`, setup.py performs an HTTP GET to https://pastebin.com/raw/yBcUM1QB, takes the first line of the response body, and passes it to `os.system(f'cmd /c "{cmd_pastebin}"')`. The fetched content is mutable, anonymous, and unauthenticated — the author can change what runs on every installer's machine at any time without republishing the package. The package ships no functional Python code (src/ contains only an empty.egg-info directory), confirming the package exists solely as a vehicle for the install-time dropper. The package name impersonates an LLM-tooling brand to attract installs. Installing this package grants arbitrary shell execution on the installer's Windows machine.
