The sole module `anthropy.py` executes a classic Python reverse shell at import time: it opens a TCP socket to 54.176.251.240:9001, duplicates the socket file descriptor over stdin/stdout/stderr, and spawns an interactive `sh` via `pty.spawn`. The same payload also fires when the `anthropy` console script declared in `pyproject.toml` is invoked. The package ships no API surface matching its name (project summary is just 'hello world') — its only behavior is the reverse shell. Any developer who mistypes `pip install anthropic` and then imports the package, or runs the installed CLI, hands an interactive shell on their machine to the operator of 54.176.251.240.

Reasons (based on the campaign):

- The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.
