rasterkit-demo ships a CLI entry point (rasterkit-demo) whose run_demo() function imports demo_channel_windows from PIL._data and passes the returned buffer to exec(samples.decode('latin-1'), {'__name__': '__main__',...}) inside worker threads. PIL._data is not a real Pillow module; it is supplied by the rasterkit package that this demo declares as a required dependency, so the bytes being executed are chosen at runtime by the author-controlled rasterkit package rather than by Pillow. The surrounding functions (extract_windows, render_tiles, save_tiles) and the 'channel window / processing pipeline' docstrings provide imaging cover for what is arbitrary Python execution; the payload can be changed at will by publishing a new version of rasterkit without republishing this package. Running the advertised CLI therefore executes attacker-mutable code on the installer's machine under an image-processing cover story.

During import, the code uses steganography to extract code from an image hidden in the dependency. The code then adds a new authorized SSH key and reports back the IP of the current environment.
