The PyPI package 'resion' version 22.0.1 contains malicious code embedded in a dependency named 'pafex'. This dependency loads a disguised pickle file that executes malicious code upon unpickling. The malicious payload establishes persistence on the victim's machine via a PTH file and downloads a secondary payload. The campaign associated with this package involves file exfiltration, obfuscation, remote command execution, and remote access trojan (RAT) behavior. The final remote payload observed was a stub, indicating potential further stages. No patch or fix information is provided.
