flashsimplelogger@0.2.0

Summary

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. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2025-07-loquru Reasons (based on the campaign): - typosquatting - obfuscation - clones-real-package - Downloads and executes a remote malicious script.
