Attackers are developing increasingly sophisticated techniques for hijacking target servers, while evading detection. One such technique that has become progressively more common is registry modification. The registry is a key component of the Windows operating system. It has a hierarchical database called “registry” that contains settings, options, and values for executables. Once the threat actor gains access to a machine, they can use reg.exe to modify their account to obtain administrator-level privileges, maintain persistence, and move laterally within the environment. The searches in this story are designed to help you detect behaviors associated with manipulation of the Windows registry.
