Updated Date: 2026-05-13 ID: 78df1df1-25f1-4387-90f9-c4ea31ce6b75 Author: Teoderick Contreras, Splunk Product: Splunk Enterprise Security

Description

Windows services are often used by attackers for persistence, privilege escalation, lateral movement, defense evasion, collection of data, a tool for recon, credential dumping and payload impact. This Analytic Story helps you monitor your environment for indications that Windows registry are being modified or created in a suspicious manner.

Why it matters

Windows Registry is one of the powerful and yet still mysterious Windows features that can tweak or manipulate Windows policies and low-level configuration settings. Because of this capability, most malware, adversaries or threat actors abuse this hierarchical database to do their malicious intent on a targeted host or network environment. In these cases, attackers often use tools to create or modify registry in ways that are not typical for most environments, providing opportunities for detection.
