setup.py downloads the first line of https://pastebin.com/raw/yBcUM1QB via urllib and passes it directly to os.system(f'cmd /c "{cmd_pastebin}"') during package installation. The Pastebin source is anonymous and author-mutable, so any installer running `pip install EzLLMGen` unconditionally executes whatever shell command is currently posted there, with no pinning, hash check, or signature. The package ships no Python modules — the src tree contains only an egg-info directory and the PKG-INFO metadata is placeholder text (Name/Author/Summary all set to 'EzLLMGen'), so there is no legitimate functionality to balance against the dropper. The install-time fetch-and-execute is the package's sole purpose.
