--- _-= Per source details. Do not edit below this line.=-_ ## 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. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-03-aioutil3 Reasons (based on the campaign): - clones-real-package - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
