Pypykatz Credentials Dumping Activity via Registry
Detects the usage of 'pypykatz' to obtain stored credentials. Adversaries may attempt to extract credential material from the Security Account Manager (SAM) database through Windows registry where the SAM database is stored. The rule specifically looks for the execution of 'pypykatz.exe' or 'python.exe' with command-line arguments indicating 'live' and 'registry' access, which are common parameters for dumping credentials from the live registry hive.
