Malicious clone of legitimate "license" package. When using the find_by_key function, the malicious code from strongly obfuscated files is loaded. It then at least collects data from cryptowallets and password managers and exfiltrate them to a hardcoded remote location.

Prior version 0.1b2, the malicious code was hosted externally and downloaded when triggered.
