The Windows Registry is one of the most powerful Windows operating system features that can tweak or manipulate Windows policies and low-level configuration settings. Because of this capability, most malware or adversaries abuse this hierarchical database to perform malicious tasks on a victim host or environment. Over the last 2 years, the Splunk Threat Research Team has analyzed and reverse engineered some of the most prevalent and successful malware families.

MITRE ATT&CK (Adversarial Tactics, Techniques, and Common Knowledge) is a comprehensive knowledge base of tactics, techniques and procedures that adversaries use to conduct cyber-attacks. The MITRE ATT&CK framework is a globally-accessible knowledge base of adversary tactics and techniques based on real-world observations.

Audit Policy: Object Access: SAM is a setting in the Windows operating system that controls the auditing of security events related to access to the Security Accounts Manager (SAM) database.
