MAL-2026-1289 Malicious code in aioutil3 (PyPI)

This is a malicious clone of legitimate python-utils. The modified code introduces a function that silently exfiltrates given data to a hardcoded location. What is interesting, during the analysis the remote domain did not exist and the malicious code was not called in the package, suggesting preparation for the further attack.
