Library disguised as FastAPI helper is executing obfuscated code during importing the module. The code is highly obfuscated; the code seems to contain an installation beacon reporting to a Telegram channel.

The package name appears as a dependency in a few Github repositories created long before publishing it, suggesting it might be an attempt to hijack the name that was previously wrongly generated by AI.
