## Source: kam193 (cb06e8bed4bc80c83b203abcee07556086a0c41f2b52d72d4a3b3740ddfa95d0)
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.
