It's a clone of "loguru" package which on import loads a second-stage script from loguru[.]guru. This makes a few checks and downloads the next stage, which is a code obfuscated with PyArmor with unclear behaviour.

The way the malicious code has been embedded could be called a "sophisticated" threat. The code is in the _logger.py in two places: the payload in L2242 as a long string constraint of only whitespaces, which are then transformed into bits and bytes, and later compiled and executed using "types.FunctionType" during initialisation of Core class.
