Adversaries with SYSTEM access to a host may attempt to access Local Security Authority (LSA) secrets, which can contain a variety of different credential materials, such as credentials for service accounts.[1][2][3] LSA secrets are stored in the registry at HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets. LSA secrets can also be dumped from memory.[4]
Reg can be used to extract from the Registry. Mimikatz can be used to extract secrets from memory.[4]

| DS0017 | Command | Command Execution |
| DS0024 | Windows Registry | Windows Registry Key Access |
Monitor processes and command-line arguments for program execution that may be indicative of credential dumping. Remote access tools may contain built-in features or incorporate existing tools like Mimikatz. PowerShell scripts also exist that contain credential dumping functionality, such as PowerSploit's Invoke-Mimikatz module,[33] which may require additional logging features to be configured in the operating system to collect necessary information for analysis.
