speed-hashes @0.1.0

Summary

setup.py defines a custom install command (NativeInstall) that runs on pip install. After the normal install step, a base64 literal (_COMPAT_PAYLOAD) is decoded and passed to exec(compile(...)) under cover-story names (_configure_native_bindings, NativeInstall) mimicking native-extension setup. The decoded Python code, on Linux, downloads an opaque binary from github.com/totti2188/8gp1Q7iZD3h4VW/releases/download/v1.3A/something to /tmp/something, chmods it 0755, and spawns it detached. Publisher metadata references github.com/nickolasburr/fast-hashes, which does not match the download source. The install lifecycle auto-executes attacker-controlled code fetched from a non-publisher GitHub account, yielding remote code execution on the installer's host.
